java - Reading nested tags with sax parser -

i trying read xml file following tag, sax parser unable read nested tags

<active-prod-ownership>   <activeprodownership>     <product code="3n3" component="tri_score" ordernumber="1-77305469" />   </activeprodownership> </active-prod-ownership>  

here code using

public class loginconsumerresponseparser extends defaulthandler {  // ===========================================================  // fields  // ===========================================================  static string str="default";  private boolean in_errorcode=false;  private boolean in_ack=false;  private boolean in_activeprodownership= false;  private boolean in_consumerid= false;  private boolean in_consumeracctoken=false;     public void startdocument() throws saxexception {   log.e("i ","in start document");  }    public void enddocument() throws saxexception {   // nothing   log.e("doc read", " ends here");  }   /** gets called on opening tags like:    * <tag>    * can provide attribute(s), when xml like:   * <tag attribute="attributevalue">*/   public void startelement(string namespaceuri, string localname,    string qname, attributes atts) throws saxexception {   if(localname.equals("ack")){    in_ack=true;   }   if(localname.equals("error-code")){    in_errorcode=true;   }   if(localname.equals("active-prod-ownership")){    log.e("in", "active product ownership");    in_activeprodownership=true;   }   if(localname.equals("consumer-id")){    in_consumerid= true;   }   if(localname.equals("consumer-access-token"))   {    in_consumeracctoken= true;   }  }   /** gets called on closing tags like:    * </tag> */   public void endelement(string namespaceuri, string localname, string qname)  throws saxexception {   if(localname.equals("ack")){    in_ack=false;   }   if(localname.equals("error-code")){    in_errorcode=false;   }   if(localname.equals("active-prod-ownership")){    in_activeprodownership=false;   }   if(localname.equals("consumer-id")){    in_consumerid= false;   }   if(localname.equals("consumer-access-token"))   {    in_consumeracctoken= false;   }  }   /** gets called on following structure:    * <tag>characters</tag> */   public void characters(char ch[], int start, int length) {    if(in_ack){   str= new string(ch,start,length);   }   if(str.equalsignorecase("success")){   if(in_consumerid){    }   if(in_consumeracctoken){    }   if(in_activeprodownership){    str= new string(ch,start,length);    log.e("active prod",str);   }   }  } } 

but on reaching tag in_activeprodownersip read "<" contents of tag

please need whole data read

the tags in xml file , parser not match. think mixing-up tags attribute names. here code correctly parses sample xml:

public class loginconsumerresponseparser extends defaulthandler {     public void startdocument() throws saxexception {         system.out.println("startdocument()");     }      public void enddocument() throws saxexception {         system.out.println("enddocument()");     }      public void startelement(string namespaceuri, string localname,                              string qname, attributes attrs)          throws saxexception {          if (qname.equals("activeprodownership")) {             inactiveprodownership = true;         } else if (qname.equals("product")) {             if (!inactiveprodownership) {                 throw new saxexception("product tag not expected here.");             }             int length = attrs.getlength();             (int i=0; i<length; i++) {                 string name = attrs.getqname(i);                 system.out.print(name + ": ");                 string value = attrs.getvalue(i);                 system.out.println(value);                         }         }                 }      public void endelement(string namespaceuri, string localname, string qname)         throws saxexception {          if (localname.equals("activeprodownership"))             inactiveprodownership = false;     }      public void characters(char ch[], int start, int length) {     }      public static void main(string args[]) throws exception {         string xmlfile = args[0];         file file = new file(xmlfile);         if (file.exists()) {             saxparserfactory factory = saxparserfactory.newinstance();             saxparser parser = factory.newsaxparser();             defaulthandler handler = new test();             parser.parse(xmlfile, handler);         }         else {             system.out.println("file not found!");         }     }      private boolean inactiveprodownership = false; } 

a sample run produce following output:

startdocument() code: 3n3 component: tri_score ordernumber: 1-77305469 enddocument()
