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.
