Re: document() function and error-handling

I will assume this is in a web environment. You could configure your web
app/server to return a well-formed error page when you get a 404 (and
disregard it if you want).

If the files are blank or valid URIs (the URI handling is correct), the transformation works as expected, but if the URI points to a non-existant file, MSXML errors out with code 0x800c0006: "The system cannot locate the object specified." I'm developing a central framework for several different applications, and I don't know if the application is actually going to create the file I'm trying to reference here. If it doesn't exist, I don't care, I just want to use it in the case that it does exist.

Is there any more graceful way (for MSXML, in particular) to handle the case where the URI passed to document() doesn't exist?
