用java向XML增加一个结点元素（ACCP认证的机试题）

用Java向XML增加一个结点元素是今年ACCP认证考试的试题，可见XML的重要性！

题目要求考生向已经给出的XML文件增加一个结点元素，答案如下：

//DomXML.java

import javax.xml.parsers.*;

import javax.xml.transform.*;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.*;

class XmlWrite

{

public static void main(String[] args)

{

try{

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder=factory.newDocumentBuilder();

Document doc=builder.parse("links.xml");

doc.normalize();

String name2="Hanzhong´s Homepage";

String sex2="male";

String phone2="22324098";

//create an element named "link"

Element link=doc.createElement("link");

/*create an element of context named "name"

context is consided with an element by w3c */

Element linkName=doc.createElement("name");

Text textName=doc.createTextNode(name2);

linkName.appendChild(textName);

link.appendChild(linkName);

doc.getDocumentElement().appendChild(link);//return a root node of document

TransformerFactory tFactory =TransformerFactory.newInstance();

Transformer transformer = tFactory.newTransformer();

DOMSource source = new DOMSource(doc);

StreamResult result = new StreamResult(new java.io.File("links.xml"));

transformer.transform(source, result);

}

catch(Exception e){}

}

//已经给出的links.xml(代码部分修改)

<?xml version="1.0" encoding="UTF-8"?>

<links>

<link>

</link>

</links>
