</document>

xml读取

获取某个标签

• doc.Print()输出整个xml
• xml中"document"下"English"标签
• TiXmlAttribute 获取并输出"English"标签属性
• element->GetText()标签下文本

#include <iostream>
#include <sstream>
using namespace std;
#include "tinyxml.h"

int main() {
	printf ("\\n** UTF-8 **\\n");
	TiXmlDocument doc( "utf8test.xml" );
	if (doc.LoadFile()) {
		cout << " utf8test.xml :\\n" << endl;
		doc.Print();
		cout << endl;
	} else {
		printf( "WARNING: File 'utf8test.xml' not found.\\n"
		        "(Are you running the test from the wrong directory?)\\n"
		        "Could not test UTF-8 functionality.\\n" );
		return 0;

	}


	TiXmlHandle docH( &doc );
	// Get the attribute "value" from the "Russian" element and check it.
	TiXmlElement* element = docH.FirstChildElement( "document" ).FirstChildElement( "English" ).Element();

	TiXmlAttribute* attribute = element->FirstAttribute();
	for (; attribute != NULL; attribute = attribute->Next() ) {
		cout << attribute->Name() << " : " << attribute->Value() << endl;
	}
	cout << " English : " << element->GetText() << endl;

	return 0;
}
