I need an unmanaged solution.

in C++

Any idea how to implement a custom URI resolver using MSXML

Cheers again. I did come across the resolver method eventually elsewhere.

Cheers, I'll check it out when I get back from my hols......

I don't want to hard code any paths in the solution.

Cheers,

Peter.

Thanks for the post.
Forgot to mention though that the root element ONLY can and will be differnt.

I've been using the document function to reference (or read in) an external named XML file OK. If I'm working in code and have the external XML in memory, in a DOM object say, can I still reference this within the transform (passing in the object into the transform perhaps?). I should add that I'm q...

When processing a particular element in the input XML file, e.g. <xsl:apply-tempate match="Feature"> ... </....> I want to test whether that specific element(identified by an attribute value) exists at the same location, relative to the root element, in a second file. The root elements of ...

I should also add that the use of an XPATH type expression within an attribute to perform the lookup was my intial solution to the problem. I basically need to hard-code some lookups within the input xml file to entries in a second xml file so any suggestions as the way to go would be appreciated.

Thanks for the information. Also I wasn't entirely clear in my original posting and made a couple of mistakes: I have 'Feature' elements in the input file (first.xml) which have attribute values which corresponds to an XPATH expression e.g. <...> <Feature expression="/root/feature/option[@name=...

pjl I should start with I'm new to XSLT/XPATH. I'm trying to use an attribute value in an input XML file as an XPATH expression to query whether an element with a named attribute exists in a second XML file. Basically I have the following: Input XML file: <Feature expression="/root/feature/opti...
