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.
