Use of TinyXML2

The recent project requires XML, and then a simple study of XML, in this simple description of the XML element parsing process, learning examples from the

http://blog.csdn.net/educast/article/details/12908455

Go here to get the XML parser file, we just need tinyxml2.h and tinyxml2.cpp, to copy them into the project directory.

Acquisition of 1.XML element content

Create a simple XML file

1 <? XML version= "1.0" ?>  2 < Hello > 3    World4</Hello>

Then write the program to get the XML element content.

1#include <iostream>2#include <fstream>3#include"tinyxml2.h"4 using namespaceTINYXML2;5 using namespacestd;6 7 voidexample1 ()8 {  9 XMLDocument Doc; TenDoc. LoadFile ("Test.xml");  One      A     Const Char* content= Doc. Firstchildelement ("Hello"),GetText ();  -cout << Content <<Endl; - }   the  - intMain () - {     - example1 (); +  -     return 0; +}

Note: Different writing formats in the XML file output different element content formats, such as the following:

2. Examples of complexity

1 <?XML version= "1.0"?>  2 <Scenename= "Depth">  3     <nodetype= "Camera">  4         < Eye>0 10 10</ Eye>  5         <Front>0 0-1</Front>  6         <Refup>0 1 0</Refup>  7         <FoV>90</FoV>  8     </node>  9     <nodetype= "Sphere">  Ten         <Center>0 10-10</Center>   One         <radius>10</radius>   A     </node>   -     <nodetype= "Plane">   -         <direction>0 10-10</direction>   the         <Distance>10</Distance>   -     </node>   - </Scene>
