Java sax program does not go to startElement () method

I am trying to use a sax parser with a custom DefaultHandler, but the strange thing is that the startElement () method in dHandler is never called. endDocument () works as it should, but prints

Total elements:0

while my xml file has 11 status elements.

even if I put total ++ outside the if statement, so it will increment every time startElement () is called, it still says 0 elements.

Please help me with this, thanks

Please check the import statement for the Attribute parameter, this should be:

import org.xml.sax.Attributes;
