The C# language, pronounced see sharp, is a superb approach to work with Java and was essentially made by Microsoft as part of Microsoft’s .NET effort. C# has a wonderfully abundant .NET library and in actual fact makes use of XML as its core technology.
In this particular short article I am going to have a general discussion of C# and XML processors, with a quick introduction to DOM tree and XML streams.
Review Of XML Processors
The idea of processing, in the context of an XML document or file, simply means to extract or pull out particular details from the file. Once pulled, this information is commonly employed to create another XML file or simply an HTML file (known as the output), this process is generally referred to as a transformation. Therefore an xml file could be processed to produce an xml or html transformation.
The specific processor which you decide upon for this task is wholly up to, however you should know that not all processors are the same and your choice is very important, the wrong choice could very well influence adversely on your whole venture.
Internet browsers like Microsoft Internet Explorer and Firefox, contain integrated XML processors and can be employed to process XML files, nonetheless they are more difficult to apply since you also need to give them processing instructions with an XSLT document, specifically for the really complicated jobs.
A much more grueling option is to work with C# and Java to write your own processor, although this really is time-consuming and you will need to use the Java or .NET class libraries.
The best option is to use a ready made XML processor, these come in an array of options such as freeware like Syntext Serna to extremely reputable, feature rich commercial grade XML processors for instance Liquid XML Studio.
Processing XML Documents
You need to use either of two approaches to process your XML file referred to as offline processing and online processing. Offline implies you do not have to be connected to your XML source file directly, alternatively you need to load your document, beforehand into memory as a DOM tree.
This is considered as the best way for processing your xml file if your xml is intended to be processed time after time because; whilst you lose memory you will get speed, which is beneficial when it comes to processing.
Online processing implies you have to be linked to your XML source file to be able to process it, consequently this really is really slow, but you do use less memory. This method is much more suited if the processing is incredibly clear-cut or maybe you are only going to process only parts of the file.
Whichever method you engage in to process your XML file, C# is versatile enough to support either method via its .NET library classes.
The basis for the online processing is the XmlReader/XmlWriter abstract classes whilst the System.Xml.XmlDocument class is the basis for offline processing.
To produce your XML document you use an XmlDocument constructor, this can create an empty XML document in memory. Within this XML document you can utilize nodes to build up an XML tree to any complexness or depth which you want, step by step.
After constructing (or loading) an XML tree, you'll be able to navigate over it and change it with XmlDocument's properties.
Finally, there are a variety of selections for processing XML files in C#, including browsers, or you might work with an XML C# tool such as Liquid XML C# tool, which helps save time in making thousands of lines of error free code, straight away from a xml or schema file.

Working With XML in C#
If you're planning to develop and alter xml files, or if you have to deal with XML and C#, you might want to check out .NET, an excellent tool that provides terrific and incredibly easy to use facilities for making use of xml files.
The key benefits of making use of .NET and XML are further boosted with the help of a set of Linq classes this means you might even use them in more general conditions, which happens to be ideal if you aren't that skilled in XML as it makes working with XML far more easier, especially if you are a newbie.
What's especially attractive about Linq is that it uses a back to fundamentals approach in terms of working with XML when compared with other standard protocols like Xpath, DOM, SAX etc simply because these protocols tend to specialise or concentrate on just one particular area of XML, whereas Linq provides a more general and simple method to working with XML.
By way of one good example, let’s examine how Linq deals with a complicated data structure like a tree as a result of XElement.
There's two core XML tags in XElement, <record> and </record>, so basically an opening and closing tag.
The guidelines are very simple and common with other markup languages like html, tags should be in matched pairs and you may nest tags So as an example if you have tag opened with <colour>, you need a closing tag </colour>.
As a side note, you may as well use an XML C# tool to produce C# code out of your xml or xml schema, which is perfect for newcomers or maybe you want to save time and also have correct, error free code.
The only exemption to the matched pair principle is if you make use of an own closing tag like <colour/> which is a tag that closes itself.
So using tags in XElement it is very easy and also straightforward to develop a tree like structure, you can also represent your tree in a program through a class.
The important point is the fact XElement encompasses a Nodes collection which is often useful to store an element’s child elements.
The whole idea about nesting XElements within XElements is pretty straightforward nevertheless , you might also do this in another, more flamboyant means, employing something named an Add method or applying an Add method in a single call.
The subsequent example ought to underscore this;
colour1.Add(colour2,colour3);
It is also possible to construct a list of child objects for placing into multiple XElement if you like or use an XElement constructor as another way to construct your XML tree.
Another way is to apply a nested method in which you use an XElement with children and continue to the levels that you want, this is known as a “functional construction” which, if you format it properly, it will look the same as the tree its is constructing and what’s more, it is also possible to pass it to any method that needs to work with it.
Lastly, you can moreover make use of the Parse and static Load methods to convert your XML into an XElement tree.
The Load method functions by taking your file specification as a URI (or as a TextReader or XmlReader) and parsing the text stream into your XElement tree.
The parse ,technique will work much the same way other than it takes a string of XML tags. The principal point of note is that you could have to manage any ensuing exceptions yourself if your XML is not right, the parsing will not work.
To conclude, there are a variety of possibilities for developing or modifying XML files in C#, as well as manual coding, or you could make use of an XML C# tool such as Liquid XML C# tool, which in turn saves you time in producing thousands of lines of problem free code, instantly from your xml or schema file.

A Review Of C++ Tools Meant For XML Users
XML is undoubtedly an hugely common area of interest among software engineers and also web-developers because it supplies a standardised and uniform way to transport knowledge throughout different programs.
More specifically, xml is the industry-standard for data exchange, through software files in xml format, or even over network connections, these network connections primarily exist for the transaction / connection and so are instantly dumped at the end of a transaction or network connection.
As such xml related tools are continually developing therefore if you intend to build up in xml you should stay up-to-date with all the current most recent tools and releases.
The majority of xml related tools are likely to be designed in Java and released in source code form, on the other hand inspite of the overwhelming prominence of JAVA based tools in the xml enviornment, there are a steady and growing quantity of C and C++ programmers who are right now also working with xml. As a result there are a great assortment of XML tools for the C and C++ programmer.
In this article, I'd like to take a look at a couple of common xml tools for example IDEs and schema designers, as these are usually fairly common tools and some knowledge would be helpful for any XML C++ programmer.
Two Sets Of Tools
There are a couple of tools that tend to be in fact critical and must be in your armoury of xml tools if you want your xml projects to be successful. The first tool falls inside of the heading of “schema designer”, your second incorporates a set of software libraries that enable you to parse and generate xml. These libraries are ingredients that are added to your selected software to allow you to build xml related features.
Creating Your Own Personal Schemas Designer
Should you prefer, it is also possible to style your own schema designer, it’s often known as a dialect designer nevertheless for the purposes of this article, I am going to utilize the phrase “schema designer”.
A schema designer is certainly a fairly basic tool, it’s basically a group of xml tags in conjunction with rules on the way the tags work together. There are 2 common ways for indicating a designer, you can use a DTD (Document Type Definition) as well as XML schema.
My recommendation would be to have a designer which has validation and a syntax checker to ensure your schema is correct, this will save you a lot of time as well as headache down the line, particularly if you have a bad schema with erroneous syntax, in relation to then validating your xml data - it won’t work due to your incorrect schema,
Design Tools
Let’s study design tools, you'll be able to opt for a straightforward text editor however these are usually quite basic and I recommend instead that you check out having a commercial quality xml editor (Liquid XML Editor is not bad) since they have particular capabilities like syntax highlighting and auto-completion which can come in fairly useful.
You will see that design tools fall under three distinct groups. Either an IDE, short for integrated development environment, that is kind of like the Swiss army knife approach because it covers every functionality and tool that you could wish. Or secondly, an xml editor, which I have already mentioned above. The third choice is to write your own personal schema or DTD.
If you are seeking to convert your xml code to C++ you ought to consider working with a XML to C++ tool to generate your code for you, you can obtain more information at http://www.liquid-technologies.com/xmldatabinding/xml-schema-to-cpp.aspx.

A Brief Article To Some Useful C++ Applications
C++ (which often is always spoken as C plus plus, is an addition to C computer programming, which was created in 1979 at Belle Labs, by a coder named Bjarne Stroustrup.
The standard ideas guiding C and C++, is the belief that you can believe in the programmer, sometimes it is equally excellent as well as negative since the compiler will never prohibit you should you do something that might make surprising or even undesirable results. On the flip side it will also not stop you if you attempt something that is unorthodox nevertheless essentially valid.
Because of this it really is critical that in case you are new to C or C++, for you to take your time to understand the code to be able to avoid any problems later on and so that you'll extract yourself if something does go awry.
In the rest of this particular article I am going to pay attention to outlining a couple of crucial C tools that any would be programmer should consider adding to their armoury.
C++ Parser Tools
A parser is a popular C program which enables you read and also interpret your xml document. To make it operate, you need to supply a DTD and your xml document. The objective of the parser is to search for proper format and then to produce your data structure for you.
C++ Validation Tools
There are a couple of types of validation in xml parsers. These are validation and non validating. Somewhat self explanatory, a validating xml parser will authenticate your xml document against your DTD or Schema prior to constructing your data structure, a non validating parser will not likely do this.
The sort of xml parser that you pick will really depend on whether or not you wish to work with a formal DTD or schemas, in case you are, then validation will be fairly critical and you need to opt for a validating parser. If not, then a validating parser is not that important.
C Parser API Models
So that you can interface software with your xml parser, you will have the option of using either of two API models, the document model or event model. The document method parses the xml data and makes what is known as an ‘object’, the object next pulls the contents of the document into a tree structure. The parser will operate on the tree structure approach.
The event model, as the name implies is generated by an occurrence and functions by employing a callback procedure to tell the parser about the structure of the xml data, this is usually at the time of parsing, hence ‘event’ model.
API standards: DOM and SAX
The parser API models cited above have been further developed into specific API standards. The W3C recommends the use of DOM as the standard document API model.
W3C Standards
While you compare functions in parsers and also other XML tools, search for support for W3C suggestions and emerging specifications, like namespaces, XPath, XLink, XInclude, and XInfoset.
Remember XML technologies are generally ageing extremely fast and that support for the primary level of a specification, such as the DOM, may lack fundamental functionality first brought about in level 2 of that specification. If performance in the most current type of a standards is important to your project, opt for your programs accordingly.
If you are wanting to change your xml code to C you must think about making use of a XML to C tool to generate your code for you, you can locate more information at http://www.liquid-technologies.com/xmldatabinding/xml-schema-to-cpp.aspx.

Obtaining The Most Out Of Your XML Schema
This short article will take a look at a few of the more complex approaches to dealing with schema design, thus this post is only suitable for people that have a good understanding of xml and xml schema. If you are a newcomer to xml you need to first acquaint yourself with the fundamentals of xml schema, the w3c school site is a superb place to begin in that respect.
For all those who've been developing for years, you could remember that historically when you wanted to verify your xml data, you had to employ a technique also known as Document Type Definition (DTD).
Practically everyone loathed working with DTD’s because they were so difficult to work with and even more tough to figure out with their alien like syntax and symbols. It’s not really unpredictable that so many folks gave up on using DTD’s to validate xml seeing that it took so much time and was so difficult that many were unable to write correct DTDs.
Thankfully, the W3C realised that DTD was not supporting the cause of xml, as they were very eager for xml to develop into the standard for markup, in particular with regards to digital and the internet.
The W3C solution was to come up with a brand-new way to validate xml, named Xml Schema. It was a much less difficult option for validating your xml and also gave developers the exact same capabilities as DTD but enhanced it substantially making it far more maintainable and extensible.
The schema serves as a blueprint for your xml file, laying down what can and also can't be included in your xml document, for instance what elements and attributes are permitted within your xml document, the values involved with those elements, the order and occurrence and so on. Which means that it’s relatively a lot like a DTD but unlike a DTD, with a schema you can in addition handle data typing, inheritance, database linkage and grouping.
The W3C Working Group at the same time introduced the notion of “document instances” that permits you to connect specific xml documents to a schema and validate your xml document against the rules in the schema.
The specs put forth by the W3C Working Group, most importantly creates a differentiation between “simple” and “complex” elements. This has fundamental considerations for programmers, simple elements can not have other elements or attributes, whereas complex elements can. Complex elements might also function as containers for other elements, that could be either simple or complex elements.
In making your xml schema, a simple type element is expressed by the <xsd:simpleType> and a complex type element is expressed by the <xsd:complexType> statement.
To be able to present simple elements in your schema, the correct way might be to use the <xsd:element> statement.
Regarding complex types, we have an additional step further than declaring the complex type, you ought to declare the type through the element, give it a name and then use this new type in the same <xsd:element> statement as per a simple element.
I really hope this article has given you some insight into xml and xml schemas, you can find out more information at w3c or w3c schools, both of which are excellent resources for grasping xml and comprehending the standard.

Why Should You Utilize XML?
Document creators and editors seem to be driven to work with XML simply because it offers a methods for describing documents, separate from of platform or software program dependancies and / or restrictions.
XML documents are able to be used for print, the world wide web or some other document method. This kind of flexibility supports information system designers to employ XML, as they are able adopt one set of specifications, tools and methods for handling documents, no matter their different syndication targets.
Online and offline print writers work with XML given that it can describe extremely structured organizations of data, as well as produce to paper as well as publish to the Web, without sacrificing document construction.
Companies that take up XML as their main document format, as opposed to an HTML or even a word processor type system, will unquestionably realize a substantial decrease in their document processing fees as well as receive improved control over the generation, sending as well as overall look of their documents. Additionally they receive a massive set of tools that provides document management and processing support which aren't available for HTML or word processor formats.
XML documents can be altered to match the needs of end users. It is extremely easy to use a couple of different style sheets to an XML document to output to several types or to manipulate information many different groups.
To illustrate, a writer will want to offer only the workouts found in a document or possibly only the theoretical components. Providing a document is adequately described, the writer can produce any view of document content that they wish.
This particular element allows for numerous procedures to generate significantly different views of the same content for other uses. When possible, content re-use saves a companies funds and also would make authors more cost-effective. XML supports and also encourages these types of processes by being variable and also modular.
XML doesn't have a set number of tags or elements, as HTML does, yet it is extensible, enabling the document developer to define purposeful tags. By utilizing XML, coders can develop a markup language that is definitely designed for their purpose. XML permits developers to create their own individual set of tags that will clearly match their demands.
Therefore while a great many folks don't need tags that support mathematical equations (MathML), setting up software programs on the internet (OSD), additionally, the swapping of financial data (OFX), mathematicians, software developers and finance companies might need such special tags.
XML lets you distinguish content from format. The layout of the XML document is actually inside a standalone style sheet. This splitting up enables you to quickly sustain and update formatting as demands change.
To illustrate the positive aspects of breaking up structure from display, we can look at a commonplace predicament which can easily happen in large and small offices on a typical basis. A document is crafted that will be wanted in several output formats, web browser, PDF and user guides.
Making use of old fashioned strategies, a different document would most likely need to be developed for each document type. By isolating structure from format, no more than one source document is necessary.
This is the actual effect of structured documents. Practicing to detache structure from format is essential to crafting superior implementation of the power of XML.

A Overview Of XML DOM As Well As Its Uses
In this article I'll try and demonstrate the nature not to mention basis for XML DOM. I shall accomplish this by breaking up XML DOM into two parts, XML and DOM. I will then wrap up by addressing the significance of xml as well as providing a bit of context into its worth.
XML stands for Extensible Markup language and as the name implies, XML can be described as markup language, it lets you split data from the format or structure(design) of a document.
In summary it's a means of moving huge files gathered from one system to another one within a standardised way which allows the collecting system to have the ability to read and comprehend the data as well as present it as it had been supposed to be presented.
In brief, XML gives a vastly adopted standard way of representing text and data inside a format which can be processed with little human or machine intelligence. Data prepared in XML could be exchanged across platforms, languages, and applications, that can be employed with a wide range of computer programming resources and utilities.
Okay, having discussed XML, lets plunge right into DOM. DOM is an acronym and stands for Document Object Model. Similar to XML, DOM is actually independent and certainly not tied to any platform or language, DOM gives a means of accessing and altering XML documents in addition to setting some document objects for XML.
A great way to think about XML DOM is to think about a tree with branches, consider the numerous elements and tags as the branches and also child elements or tags( and their joining attributes) as the twigs. XML DOM helps you view your xml document graphically, as a tree and adjust your elements, and attributes through this DOM tree.
If you wish to change the tree, say by adding or getting rid of some of the branches or twigs, something which is in fact fairly common for web programmers, that can be done possibly by yourself, or you may work with an xml editor which has an xm parser, to accomplish it for you.
Many good xml editors ought to be appropriate for the majority of the more popular languages, such as Asp, Javascript, Visual Basic, among others. Some of the better xml editors can also be used to check the syntax of the XML as needed, referred to as xml validation in most xml editors, so do check that your chosen xml editor has an xml validation function.
Loading your XML document straight into your XML DOM so that you may make your tree is also very painless. To be able to load an entire XML file utilize the load( ) method, to load a text string work with the loadXML( ) method.
Now that we have talked about both XML and DOM, I would like to conclude by exploring just why it is significant and why software engineers might want to employ it.
Throughout the early days of the internet, online browsers and sites had been really easy, using bare html, standardisation was not a obstacle and so websites could be viewable in very much the same way regardless of the browser being utilized.
On the other hand with the beginning of the wireless internet as well as the ensuing explosion in wireless / portable systems from laptops, smartphones, tablets and other such products, the need to make sure compatibility between diverse browsers and devices grew to be increasingly important.
The answer came with the creation of new languages and specs such as XHTML, XSL and XML, the latter becoming the most vital and beneficial advancement of them all.
XML made it possible for web designers to clearly define data without the need of instructing the web browser just how to show the data, contrary to HTML, which both defines the data and also informs the browser the correct way to present it.
XML data can certainly be viewed on just about any platform or browser due to the fact it is a uncomplicated text file with absolutely no predefined tags, letting the coder to delineate data any number of ways.
XML stands for Extensible Markup language and as the name implies, XML can be described as markup language, it lets you split data from the format or structure(design) of a document.
In summary it's a means of moving huge files gathered from one system to another one within a standardised way which allows the collecting system to have the ability to read and comprehend the data as well as present it as it had been supposed to be presented.
