Re: Lookup without document('') function
Well, assuming you can't switch processors as outlined by Kip in that very on-topic post....

Technically I can probably put the lookup table in the input source since I'm getting it back from a Database Query. One other question, is there any way to use XPath to eliminate duplicates from a Node Set.
Yes, but we need to understand what you mean by "duplicate".
Since my XML I'm dealing with looks something like:
Yes, de-duplicating is possible; you most commonly see it as a step along the way to grouping.
The most popular and friendly way, assuming you're familiar with keys, is to declare a key that lets you retrieve nodes by their value, and then when you process a node, test whether it's the first (or last) of the nodes retrieved by the key with the current value. This can be done either with the generate-id() function or by using a counting-the-union approach for testing node identity.
That's the explanation in prose; more useful to you would be to see the code, which you can find in any resource like the XSL FAQ, www.jennitennison.com, or any on- or off-line resource that describes grouping in XSLT 1.0.
I'll keep looking for an interface to a processor that supports the document() function as that is the easiest way I can see in getting this to work (the site this will be implemented on is using XALAN so I don't have to worry about it when its in production).
