Hi Shinnie
<BR>
<BR>
I had a similar problem, and I believe there are 2 ways of doing it:
<BR>
<BR>
1) Using ElementFilter and your own JDOMFactory implementation, which would create only the elements you need.
<BR>
<BR>
2) Using dom4j API instead, which seems to be more geared to large (preferably with a shallow tree) XML documents. Have a look at:
<BR>

Best regards
