RE: Using document() to check the existance of a file

> I'd like to check the existance of an file with the document function.

Unfortunately you can't do this in a standard way. It's an error for the
document function to reference a file that doesn't exist; the processor is
allowed to (but not required to) recover from the error by returning an
empty node-set.

With Saxon 5.5, you can control whether Saxon reports such errors and stops,
reports them and continues, or recovers silently: but if you rely on this,
your stylesheet won't be portable.
