Write a sax parsing XML document that belongs to you

First you need an XML document

<?xml version= "1.0" encoding= "UTF-8"?>< Bookshelf >  < book >    < title >hack36 meter </title >    < Price >78</Price >    < author > laosi </author >  </book > <  book > <    title >android Advanced Programming < /title >    < price >89</Price >    < author > Leave your windbreaker </author >  </book >  < book >    < title >c++ Advanced Architecture </title >    < price >56</Price >    < author > depressed lifelong </author >  </book ></bookshelf >

Then use the program to parse it, the main process of parsing is to obtain the title of the third book

Describe the parsing process of sax in detail

Sax parsing is the parsing of tag names, using the name of the tag to parse

The process of parsing is to have a reader to read the XML document,

Then there is a content trigger to process the resulting content,

So the process of Sax parsing is as follows

Package Com.jack.xml;import Java.io.ioexception;import Javax.xml.parsers.parserconfigurationexception;import Javax.xml.parsers.saxparser;import Javax.xml.parsers.saxparserfactory;import Org.xml.sax.Attributes;import Org.xml.sax.contenthandler;import Org.xml.sax.locator;import Org.xml.sax.saxexception;import Org.xml.sax.xmlreader;public class Xmlparsetest {//Create Content Resolution object ContentHandler handler = new ContentHandler () {String name = n Ull;int count = 0; @Overridepublic void Startdocument () throws Saxexception {//TODO auto-generated method STUBSYSTEM.OUT.P Rintln ("Start parsing to document");} @Overridepublic void Enddocument () throws Saxexception {//TODO auto-generated method StubSystem.out.println ("End of document parsing");}  @Overridepublic void Startelement (String uri, String localname, String Qname,attributes atts) throws Saxexception {//TODO Auto-generated method stubthis.name = QName;}  @Overridepublic void characters (char[] ch, int start, int length) throws Saxexception {//TODO auto-generated method stubif ("title".
