book.xml(需要解析的XML文档)

<?xml version="1.0" encoding="UTf-8">
<books>
     <book bookno="001">
        <title>大数据时代</title>
        <author>张三</author>
        <price>50</price>
     </book>
     
     <book bookno="002">
        <title>Andriod开发</title>
        <author>李四</author>
        <price>70</price>
     </book>
</books>

Book.java(文档的构造)

package bo;
 
public class Book {
   public String bookno;
   public String title;
   public String author;
   public double price;
public String getBookno() {
	return bookno;
}
public void setBookno(String bookno) {
	this.bookno = bookno;
}
public String getTitle() {
	return title;
}
public void setTitle(String title) {
	this.title = title;
}
public String getAuthor() {
	return author;
}
public void setAuthor(String author) {
	this.author = author;
}
public double getPrice() {
	return price;
}
public void setPrice(double price) {
	this.price = price;
}
@Override
public String toString() {
	return "Book [author=" + author + ",bookno=" + bookno + ",price=" + price
			+ ",title=" + title + "]";
}
public Book() {
	super();
	// TODO Auto-generated constructor stub
}
public Book(String bookno,String title,String author,double price) {
	super();
	this.bookno = bookno;
	this.title = title;
	this.author = author;
	this.price = price;
}
 
   
}
 

XmlParse.java(接口类，供SaxParse调用)

package bo;
import java.util.List;
public interface XmlParse 
{
  public List<Book> xmlparse(String fileName);
  
}
 

Mysax.java(解析的功能实现类)

package sax;
import java.util.ArrayList;
import java.util.List;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
 
import bo.Book;
public class Mysax extends DefaultHandler {
    private String tag;
    private Book book;
    private List<Book> list;
    public List<Book> getList()
    {
    	return list;
    }
	@Override
	public void characters(char[] arg0,int arg1,int arg2) throws SAXException {
		// TODO Auto-generated method stub
		super.characters(arg0,arg1,arg2);
		if(tag!=null)
		{
			String string=new String(arg0,arg2).trim();
			if(tag.equals("tital"))
			{
				 book.setTitle(string);
			}
			if(tag.equals("author"))
			{
				book.setAuthor(string);
			}
			if(tag.equals("price"))
			{
				book.setPrice(Double.parseDouble(string));
			}
		}
		
		
	}
 
	@Override
	public void endDocument() throws SAXException {
		// TODO Auto-generated method stub
		super.endDocument();
	}
 
	@Override
	public void endElement(String arg0,String arg1,String arg2)
			throws SAXException {
		// TODO Auto-generated method stub
		super.endElement(arg0,arg2);
		if(arg2.equals("book"))
		{
			list.add(book);
			book=null;//为下一步解析做准备
		}
		tag=null;
	}
 
	@Override
	public void startDocument() throws SAXException {
		// TODO Auto-generated method stub
		super.startDocument();
		list=new ArrayList<Book>();
	}
 
	@Override
	public void startElement(String arg0,String arg2,Attributes arg3) throws SAXException {
		// TODO Auto-generated method stub
		super.startElement(arg0,arg2,arg3);
		if(arg2.equals("book"))
		{
			book=new Book();
			String bookNo=arg3.getValue("bookno");
			book.setBookno(bookNo);
		}
		tag=arg2;
	}
  
}
 

SaxParse.java(解析主类，调用其他类，实现其解析功能)
