version problems

[Judi Thomson <gr...@yahoo.com>]

The code pasted below works as expected using an older
version of xalan and xerces  (libraries dated
5/4/2001)
(Actually I borrowed most of the code from an earlier
posting to the list- manyt thanks to the original
author!)

We 'upgraded' to a newer version (libraries dated
8/16/2001) and the same code crashes with an access
violation at the call to theLiason.createDocument(). 

I can move the point at which I get the access
violation by changing the order of the declarations. 
But I simply cannot see how to get rid of it.

any advice greatly appreciated.

Thanks!
