1. 首先下載這tinyxml官方文件庫。
http://download.csdn.net/download/llhhyy1989/4722355
2. 將其中文件放在目錄下。建立test.xml文件
<Server>
<item>
<entrust_price>100.00</entrust_price>
<entrust_amount>1.0</entrust_amount>
<operator>10000</operator>
<entrust_direction>1</entrust_direction>
</item>
<item>
<entrust_price>101.00</entrust_price>
<entrust_amount>2.0</entrust_amount>
<operator>10001</operator>
<entrust_direction>2</entrust_direction>
</item>
<!--more contacted persons.-->
</Server>
3.建立main.cpp文件
#include"tinyxml.h"
#include"tinystr.h"
#include<iostream>
#include<string>
#include<stdio.h>
#include<stdlib.h>
using namespacestd;
int main()
{
/*way1. const char* filepath ="test.xml";
TiXmlDocument doc(filepath);
bool loadOkay = doc.LoadFile();
if (!loadOkay) {
cout<<"Could not load testfile."<<endl;
exit( 1 );
return 0;
} */
/*way2*/
string xml_data ="<Server><item><entrust_price>100.00</entrust_price><entrust_amount>1.0</entrust_amount><operator>10000</operator><entrust_direction>1</entrust_direction></item><item><entrust_price>101.00</entrust_price><entrust_amount>2.0</entrust_amount><operator>10001</operator><entrust_direction>2</entrust_direction></item></Server>";
TiXmlDocument *doc = new TiXmlDocument();
doc->Parse(xml_data.c_str(),0,TIXML_ENCODING_UNKNOWN);
TiXmlElement* root =doc->RootElement();
for( TiXmlNode* item = root->FirstChild( "item"); item; item = item->NextSibling( "item" ) ) {
TiXmlNode* child =item->FirstChild();
const char* entrust_price =child->ToElement()->GetText();
if (entrust_price) {
cout<<"entrust_price:"<<entrust_price<<endl;
} else {
cout<<"entrust_price:"<<endl;
}
child =item->IterateChildren(child);
const char* entrust_amount =child->ToElement()->GetText();
if (entrust_amount) {
cout<<"entrust_amount:"<<entrust_amount<<endl;
} else {
cout<<"entrust_amount:"<<endl;
}
child =item->IterateChildren(child);
const char* operator_no =child->ToElement()->GetText();
if (operator_no) {
cout<<"operator_no:"<<operator_no<<endl;
} else {
cout<<"operator_no:"<<endl;
}
child =item->IterateChildren(child);
const char* entrust_direction =child->ToElement()->GetText();
if(entrust_direction) {
cout<<"entrust_direction:"<<entrust_direction<<endl;
} else {
cout<<"entrust_direction:"<<endl;
}
cout<<endl;
}
delete doc;
}
其中方法一：主要是讀取本地配置文件，需要的時候指針指向的改爲對象引用
其中方法二：主要是針對XML報文，進行數據的傳輸。
