android - Java handling XML using SAX -


i've got xml need parse given structure:

<?xml version="1.0" encoding="utf-8"?>  <root>   <tag label="idad">     <child label="text">text</child>   </tag>   <tag label="idnumpage">     <child label1="text" label2="text">text</child>   </tag> </root> 

i use sax parser parse it:

rootelement root=new rootelement("root"); android.sax.element page_info=root.getchild("tag").getchild("child"); page_info.setstartelementlistener(new startelementlistener() {              @override             public void start(attributes attributes) {                 /*---------------*/             }         }); 

i want read second "tag" element attributes(label1 , label2), startelementlistener reads first tag, because have same structure , attributes(those label="idad" , label="idnumpage") distinguish them. how tell startelementlistener process second <tag> element?

if stuck startelementlistener-way, should set listener tag element, , when it's label equals "idnumpage" set flag, other startelementlistener you've set on child element should read.

update
below sample of how using these listeners:

android.sax.element tag = root.getchild("tag"); final starttagelementlistener listener = new starttagelementlistener(); tag.setstartelementlistener(listener);  android.sax.element page_info = tag.getchild("child"); page_info.setstartelementlistener(new startelementlistener() {     @override     public void start(attributes attributes)     {         if (listener.readnow())         {             //todo: in tag label="idnumpage"         }     } }); 

and starttagelementlistener implemented readnow getter, let know when read child tag's attributes:

public final class starttagelementlistener implements startelementlistener {     private boolean doreadnow = false;      @override     public void start(attributes attributes)     {         doreadnow = attributes.getvalue("label").equals("idnumpage");     }      public boolean readnow()     {         return doreadnow;     } } 

ps: did consider using org.xml.sax.helpers.defaulthandler implementation task?
