No, I haven't.  It's an excellent tool, but I need one that can query in 
"command-line" mode rather than shell mode.

Your diagnosis is spot on.  Not being an XML expert I'm embarrassed to 
admit I wasn't aware of the flattened versions available for download.  
I've just tried XML::ParseDTD on a flattened version and it worked 
perfectly.  This module appears to be the solution to my problem.

Thanks for the tip.  I have one last question: Is there a simple way to 
produce a flattened DTD from a modular one using commonly available tools?
