XOM API for Processing XML with Java

[Wolfgang Hoschek <wolfgang.hoschek AT mac.com>]

This example works fine here with a 10 MB heap (java -Xmx10m) and the  
nux-1.6 release. I just downloaded the DBLP data (400 MB) again and  
ran your snippet with sun java-1.5. BTW, since the DBLP data includes  
a lot of external entities you need to bump up the entity expansion  
limit according to http://java.sun.com/webservices/docs/1.5/jaxp/ 
ReleaseNotes.html via

System.setProperty("entityExpansionLimit", String.valueOf 
(Integer.MAX_VALUE));

More detailed config and version info for your environment might help  
to pinpoint the problem.
