我从网上找了一个DOM解析XML的程序,程序基本理解了,就是没有测试成功,我不知道XML应该放在什么地方才可以读取,希望大家给指点一下,我把代码拿出来共享一下:
package com.lly.test;
import javax.xml.parsers.*;
import java.io.*;
import org.w3c.dom.*;
import org.xml.sax.*;
/*
* XML范例
* <?xml version="1.0" encoding="gb2312"?>
<books>
<book email="zhoujunhui">
<name>rjzjh</name>
<price>jjjjjj</price>
</book>
</books>
*/
public class DomParseXml
{
public DomParseXml()
{
DocumentBuilderFactory objDBF = DocumentBuilderFactory.newInstance() ;
try
{
DocumentBuilder objDB = objDBF.newDocumentBuilder();
InputStream objIS = new FileInputStream( "bin/libary.xml" );
Document objD = objDB.parse( objIS );
Element objE = objD.getDocumentElement();
NodeList objNL = objE.getChildNodes() ; // 节点的集合
if ( objNL != null )
{
for ( int i =0 ; i < objNL.getLength() ; i ++ )
{
Node objN = objNL.item( i );
if ( objN.getNodeType() == Node.ELEMENT_NODE )
{
String strEmail = objN.getAttributes().getNamedItem( "email" ).getNodeValue();
System.out.println( "email--->" + strEmail );
for ( Node objSN = objN.getFirstChild() ; objSN != null ; objSN = objSN.getNextSibling() )
{
if ( objSN.getNodeType() == Node.ELEMENT_NODE )
{
if ( objSN.getNodeName().equals( "name" ))
{
String strName = objSN.getNodeValue() ;
String strNName = objSN.getFirstChild().getNodeValue();
System.out.println( "strName--->" + strName );
System.out.println( "strNName--->" + strNName );
}
if (objSN.getNodeName().equals( "price" ))
{
String strPrice = objSN.getNodeValue() ;
System.out.println( "strPrice-->" + strPrice );
}
}
}
}
}
}
}
catch ( ParserConfigurationException e )
{
e.printStackTrace();
}
catch(IOException e)
{
e.printStackTrace();
}
catch(SAXException e)
{
e.printStackTrace();
}
}
public static void main(String args[])
{
new DomParseXml();
}
}
