My assumption is that you are using .NET and this is custom URIResolver
that you are referring to?  Either way, it doesnt matter because the
easiest way to solve your problem is to wrap the document() function
within a boolean() function which will evaluate to true if the file
exists and false if it does not.  You can also wrap string() and
concat() within the document() function to use a dynamically created
reference to a file... for example

boolean(document(string(concat('/foo/bar/', $foobar, '.xml'))))

when used within a test attribute would evaluate to true if the string
created by the concat() function existed in that location.

Best of luck!

Subject: [xsl] Using a custom URIResolver

Hello all,

I'm using a custom URIResolver in a transformation. This is because I'm
using the document function to find related documents for the document
that is currently being transformed. What I want is that only when the
referenced file is not being found by the default URIResover, that my
custom URI Resolver takes over and finds a template to be used for that
single transformation.

The problem that I have is that I first want the default URI Resolver to
act and only when it's result is null or an exception, that my custom
URI resolver takes over. Until now I can only find how to use the
default URI resolver (in case my own URI resolver cannot resolve the
reference) by using null as the return value of the resolve() method.

Is there anybody who knows how to solve this problem or else what the
code is for the default implementation of the default URI resolver so
that I can modify it to let it act as I want it to?

Thanks in advance!

Best regards,

Bjvrn Boxstart
