processElement

protected boolean processElement(String namespaceURI,
                                 String localName,
                                 Attributes attributes)

localName - tag local name (i.e. w/o namespace prefix)

attributes - tag attributes

Returns:

true if tag was processed

Throws:

SAXException - can be thrown to abort parsing
