使用Stax解析XML


		首先是我们用到的位于src下面的books.xml
[html] 
<?xml version="1.0" encoding="UTF-8"?>  
<bookstore>  
    <book category="COOKING" aaaaaa="111111">  
        <title lang="en">Everyday Italian</title>  
        <author>Giada De Laurentiis</author>  
        <year>2005</year>  
        <price>30.00</price>  
    </book>  
    <book category="CHILDREN">  
        <title lang="en">Harry Potter</title>  
        <author>J K. Rowling</author>  
        <year>2005</year>  
        <price>29.99</price>  
    </book>  
    <book category="WEB">  
        <title lang="en">XQuery Kick Start</title>  
        <author>James McGovern</author>  
        <author>Per Bothner</author>  
        <author>Kurt Cagle</author>  
        <author>James Linn</author>  
        <author>Vaidyanathan Nagarajan</author>  
        <year>2003</year>  
        <price>49.99</price>  
    </book>  
    <book category="WEB">  
        <title lang="en">Learning XML</title>  
        <author>Erik T. Ray</author>  
        <year>2003</year>  
        <price>39.95</price>  
    </book>  
</bookstore>  
 
下面是Stax用法
[java]

import javax.xml.parsers.DocumentBuilder;
