tinyxml的用法和实例

现在很多协议都用xml来设计，方便扩展，也具有兼容性。现在流行的json和gson就不说了，应用比较多的tinyxml也是很不错的。下面介绍下tinyxml的用法和实例。

使用tinyxml，需要在工程中包含其源码，并在头文件建立引用关系。下面是一个简单的例子，按照层次关系打印出xml文件。

代码如下：

#include "stdafx.h"
#include "targetver.h"
#include "tinystr.h"
#include "SystemCommon.h"
#include "tinyxml.h"  

void ParseXML(TiXmlElement *Element); 

int _tmain(int argc, _TCHAR* argv[])
{ 

    char c[2048] =  "<!-- This is a comment -->"
                    "<?xml version=\"1.0\"  encoding=\"utf-8\"?>"
                    "<Class name=\"计算机软件班\">计算机"
                    "<Students>"
                    "<student name=\"张三\" studentNo=\"13031001\" sex=\"男\" age=\"22\">"
                    "<phone>88208888</phone>"
                    "<ET name=\"de\" ground = \"ground\">on the ground</ET>"
                    "<et name = \"et name\" ball = \"ball\"/>"
                    "<address>西安市太白南路二号</address>"
                    "</student>"
                    "<student name=\"李四\" studentNo=\"13031002\" sex=\"男\" age=\"20\">"
                    "<phone>88206666</phone>"
                    "<address>西安市光华路</address>"
                    "</student>"
                    "</Students>"
                    "</Class>";
    TiXmlDocument *myDocument = new TiXmlDocument(); 

     //假设文件名是xml.xml
    myDocument->LoadFile("xml.xml",TIXML_ENCODING_UTF8);
    //myDocument->Parse(c, 0,TIXML_ENCODING_UNKNOWN);
    TiXmlElement *rootElement = myDocument->RootElement(); 

    while(rootElement)
    {
        ParseXML(rootElement);
        rootElement = rootElement->NextSiblingElement();
    } 

    delete myDocument; 

    cout<<"----------------END-----------------"<<endl;
    return 0;
} 

void PrintTree(int c)
{
    if(c <= 0)
        return ;
    while(c)
    {
        cout<<" ";
        --c;
    }
    return;
} 

//调用 tinyxml 解析 xml
void ParseXML(TiXmlElement *pElement)
{
    static int i= 0;
    PrintTree(i);
    cout<<pElement->Value()<<" ";
    const char * str = NULL;
    if(str = pElement->GetText())
        cout<<" "<<str<<endl;
    else
        cout<<endl; 

    TiXmlAttribute* attributeOfStudent = pElement->FirstAttribute();
    while(attributeOfStudent)
    {
        PrintTree(i);
        std::cout << attributeOfStudent->Name() << " : " << attributeOfStudent->Value()<<std::endl;
        attributeOfStudent = attributeOfStudent->Next();
    }
    TiXmlElement* ChildElement = pElement->FirstChildElement();
    while(NULL != ChildElement)
    {
        i++;
        ParseXML(ChildElement);
        i--;
        ChildElement = ChildElement->NextSiblingElement();
    }
}

例如要解析的文件内容是

<?xml version="1.0" encoding="utf-8"?>
<!-- This is a comment -->
<Class name="Class of SoftWare">
    <Students>
      <student name="LiLei" studentNo="13031001" sex="Man" age="22">
        <phone>88208888</phone>
        <ET name="de" ground = "ground">on the ground
           <et name = "et name" ball = "ball"/>
        </ET>
        <address>Road1</address>
      </student>
      <student name="LiSi" studentNo="13031002" sex="Man" age="20">
        <phone>88206666</phone>
        <address>Road2</address>
      </student>
    </Students>
