　　TinyXML is an open source parsing XML parsing library, can be used in C + +, can be compiled in Windows or Linux, using TinyXML for C + + XML parsing, simple and easy to use.
The model of this analytic library parses the XML file and then generates the DOM model in memory, which makes it easy to traverse the XML tree.

TinyXML version:tinyxml_2_6_2

Running environment Windows

There are two headers in it. tinystr.h tinyxml.h
Four source files tinystr.cpp tinyxml.cpp tinyxmlerror.cpp tinyxmlparser.cpp
A testing test file xmltest.cpp

Tixmlbase: The base class for the entire TinyXML model. Tixmlattribute: A property that corresponds to an element in XML. Tixmlnode: Corresponds to a node in the DOM structure. Tixmlcomment: Corresponds to the comment in the XML. Tixmldeclaration: Corresponds to the declaration part of XML, namely < versiong="1.0" ?>. Tixmldocument: The entire document that corresponds to XML. Tixmlelement: The element that corresponds to the XML. Tixmltext: Corresponds to the text portion of the XML. Tixmlunknown: Corresponds to an unknown part of XML. Tixmlhandler: Defines some operations for XML. 

To create a simple XML

<?xml version= "1.0" encoding= "UTF-8"?>  <school name= "Computer Academy" >      <class name = "C + +" >          < Student name= "Wang Ling" number= "052140" >              <email>[email protected]</email>              <address> Henan </ address>                   </Student>          <student name= "song June" number= "024561" >              <email>[email protected] </email>              <address> Hebei </address>                   </Student>      </Class>  </school >
