illegal characters in large XML files

Hi All

Here is our problem.

We are populating a database from a large xml file and at some point the
database breaks into an infinite loop in the Stored Procedure due to the
existence of one or more illegal characters.

We are trying to find out if it is possible to create a report using XSL to
identify the so called offending nodes, requesting something like a list of
nodes that contain anything that is not an alphanumeric character, and then
throw some exceptions like . . . Ignore '@', '£', '*' etc . . 

Thanks in advance
