Parsing XML and Storing values in instance variable

Question

hi,
i'm new to XML.
here i'm trying to parse an XML and store their element data to the instance variable.
in my main method i'm tried to print the instance variable. but it shows "" (ie it print nothing ).
i know the reason, its becas of the the endElement() event generated and it invokes the characters() and assigns "" to the instance variable.
my main perspective is to store the element data in instance variable.
thanks in advance.

pa.setContentHandler(this);
pa.parse(url);

          ctelement = localName;     
     public void endElement(String uri,String localName,String qName) throws SAXException
     public void characters(char[] ch,int start, int length) throws SAXException
          try
               if(ctelement.equals("name"))
                    vname = new String (ch,start,length);
                    System.out.println("The method "+vname1);
          }catch (Exception e)
               System.out.println("The exception "+e);
     public static void main(String args[])
          try
          mysax ms = new mysax();
          ms.doparse(args[0]);
          System.out.println("the contents name "+ms.vname1);
          catch(Exception e)
               System.out.println("this is exception at main" +e);
my XML looks like
<coyprofile_result>
<company>     
<name>abcTech</name>
<rcbreg>123456789</rcbreg>
<address>Singapore</address>
<country>sg</country>
<telephone>123456</telephone>
<fax>123155</fax>
</company>
</coyprofile_result>

I believe that the problem has to do with the value you assign to ctelement. You are assigning the value of localName to ctElement, however for the element: <name>...</name> the localname is empty string i.e. "", but qName equals "name". Because you are assigning empty string to ctElement, when you do the comparison in characters of ctElement to "name" it will always be false. So in startElement change it to ctElement = qName; Try it and see if it works. I have produced similar programs and it works for me.
Hope this helps.
