------解决方案--------------------
然而从xml文件中解析以后的数据收集可以用SAX试试看
我这里有个简单的例子，希望对LZ有用

Java code

package com.test.xml;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
public class SAXParseHandler extends DefaultHandler{
    public void startDocument()throws SAXException{
        System.out.println("起始文挡");
    }
    public void endDocument()throws SAXException{
        System.out.println("结束文挡");
    }
    public void characters(char[] ch,int start,int length)throws SAXException{
        String charString=new String(ch,start,length);
        System.out.println("字符:"+charString);
    }
    public void startElement(String namespaceURI,String localName,String qName,Attributes atts)throws SAXException{
        System.out.println("起始元素:"+qName);
        for(int i=0;i<atts.getLength();i++){
            System.out.println("属性值:"+atts.getValue(i));
        }
    }
    public void endElement(String namespaceURI,String localName,String qName)throws SAXException{
        System.out.println("结束元素:"+qName);
    }
}

------解决方案--------------------
Java code

package com.test.xml;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

public class Books {
    /**
     * @param args
     */
    public static void main(String[] args) throws Exception{
        // TODO 自动生成方法存根
        SAXParserFactory factory=SAXParserFactory.newInstance();
        SAXParser parser=factory.newSAXParser();
        parser.parse("booksamp.xml",new SAXParseHandler());

    }
