介绍用Java解析网络数据的三种特殊方法

// HelloXml.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <iostream.h>
#include <libxml/parser.h>
#include <libxml/xpath.h>

	xmlNodePtr curNodePtr;  //定义结点指针
	
	doc = xmlReadFile(szConfigFilename,"GB2312",XML_PARSE_RECOVER);  //解析文件 
	if (doc == NULL ) 
	{
		fprintf(stderr,"Document not parsed successfully. \n"); 	
		xmlFreeDoc(doc); 
		exit(1);
	} 	
	curNodePtr = xmlDocGetRootElement(doc);  //确定文档根元素

	if (curNodePtr == NULL)
	{
		fprintf(stderr,"empty document\n"); 
		xmlFreeDoc(doc); 
		exit(1);
	}
	
	//读取xml文档中的内容并赋值给对象属性
	xszRel = xmlNodeGetContent(curNodePtr);

		cout<<"HELLO, XML CONFIG FILE. content = "<<xszContent<<endl;
		xmlFree(xszContent);
