最近正在做的一个项目里涉及到xml文件的存取，同事推荐的tinyxml++ ,是c++版本的xml解析包，据说很小巧，好用，于是download了一个下来.顺便在其官方主页上下载了premake.exe用来生成工程文件的.以下是premake的用法.

Windows

<table style="padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:auto; margin-bottom:0px; margin-left:auto; font-size:12px"> 
 <tbody style="padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px"> 
  <tr style="padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px"> 
   <td style="padding-top:5px; padding-right:5px; padding-bottom:5px; padding-left:5px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; border-right-color:rgb(170,170,170); border-right-width:1px; border-right-style:solid; border-top-color:rgb(170,170,170); border-top-width:1px; border-top-style:solid; border-left-color:rgb(170,170,170); border-left-width:1px; border-left-style:solid; border-bottom-color:rgb(170,170,170); border-bottom-width:1px; border-bottom-style:solid"> <span style="font-family:NSimsun; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px">premake --target cb-gcc [--unicode] [--ticpp-shared] [--dynamic-runtime]</span></td>

我这里是默认生成CodeBlocks for gcc的工程文档.

生成之后打开文件进行编译,得到两个文件.libticpp.a, libticppd.a  在需要用到的工程里链接就行了.

具体的编译配置网上已经有很多教程，不明白的可以去看.

先看看运行效果图 ![200811081226079499359.jpg][]

下面开始针对tinyxml编程.

1：新建一个xml文档 取名 config.xml,内容如下:

<? xml  version ="1.0"  encoding ="UTF-8"  ?>   
< ApplictionConfig >   
         < RoNum >0 </ RoNum >   
         < AutoStart >0 </ AutoStart >   
         < TimeInterval >100 </ TimeInterval >   
         < BgPic >D:\\devCode\\desktopDev\\new iLed\\sound\\main.wav </ BgPic >   
         < BgMusic >D:\\devCode\\desktopDev\\new iLed\\pic\\4.png </ BgMusic >   
</ ApplictionConfig >

一共5个属性配置.

然后开始写代码.

ilcdDemoReadConfig.h

![InBlock.gif][]\#ifndef ILCDSETXMLCONFIG\_H\_INCLUDED   
![InBlock.gif][]\#define ILCDSETXMLCONFIG\_H\_INCLUDED   
![InBlock.gif][]   
![InBlock.gif][]                                 //是否自启动字符串定义   
![InBlock.gif][]                                 const  char\* AutoStartStr;   
![InBlock.gif][]                                 //时间间隔字符串定义   
![InBlock.gif][]                                 const  char\* TimeIntervalStr;   
![InBlock.gif][]                                 //背景图片字符串定义   
![InBlock.gif][]                                 const  char\* BgPicStr;   
![InBlock.gif][]                                 //背景音乐字符串定义   
![InBlock.gif][]                                 const  char\* BgMusicStr;   
![InBlock.gif][]                                 //循环轨迹次数字符串定义   
![InBlock.gif][]                                 const  char\* RotateNumStr;   
![InBlock.gif][]   
![InBlock.gif][]   
![InBlock.gif][]\#endif  // ILCDSETXMLCONFIG\_H\_INCLUDED

iLcdSetMain.cpp中读取文档的部分

记得要加入 一下两个头文件

![InBlock.gif][]\#include  "tinyxml.h"  // TinyXML的头文件   
![InBlock.gif][]\#include  "tinystr.h"  // TinyXML的头文件

![InBlock.gif][] void iLcdSetFrame::ReadXmlFile()

![InBlock.gif][]        doc.LoadFile();   
![InBlock.gif][]        TiXmlElement\* root = doc.FirstChildElement( "ApplictionConfig");   
![InBlock.gif][]         if (root) //检测主节点ApplictionConfig是否存在   
![InBlock.gif][]        \{   
![InBlock.gif][]                 //自启动节点   
![InBlock.gif][]                TiXmlElement\* AutoStartElement = root->FirstChildElement( "AutoStart" );
