Hi all,
I am using IBM's xmlj2.0.3 XML parsers. I am having the following   
When i set my own document handler with a DOMParser, the handler is never   
invoked upon. However when i use the SAXParser it does. Why does the   
DOMParser not invoke the DocumentHandler yet hte SAXParser does?
The docs does not throw any light on the problem.
Is there a fundamental problem with using a DocumentHandler with a

I don't know about the version of your XML4J, but in mine (1.1.9), the
documentation states that DocumentHandler is to be used with the SAX Parser
to eb informed of parsing events. This is logical, since the main difference
is that DOM parsers parse the whole document into a resulting DOM tree, and
SAX parsers are used for event based processing. 

There doesn't appear to be any way to create a DocumentHandler on class
com.ibm.xml.parser.Parser, but you can from org.xml.sax.DocumentHandler. Did
they change this in your newer version?
