I had to parse a four large Lawson Report Writer XML document (up to
several hundred megs big ).   Its structure was not deep and was
consistence enough but repeated an unknown number of times.  I first
coded the XML-INTO with a handler.   During testing it took about 3
minutes for the documents to be processed.  I ended up going to the
XML-SAX (I forget the exact reason but it was because of the document I
had to process), when I was done figuring out all the needed handler
code the same documents processed in 30 seconds. 

It was more work with the XML-SAX but I learned a lot from the
experience. 

Below are code samples I used to build my experience with the XML-SAX
parser.

try them out.

Are you using %handler because the PO data structure is too big when you

make the arrays as big as you need? (Just curious.)

        Yes that is correct.

The example I sent just showed one POChange set.  There will be multiple

POChange sets and I wanted to be able to process an XML file that had an

unknown number of these sets.

Thanks,

No, if you need to handle the ChangePODetail's using %handler, you'd 
have to handle anything at the same level separately.

Are you using %handler because the PO data structure is too big when you

make the arrays as big as you need? (Just curious.)
