Chris,
I would be wary of using cfscript just for supposed performance gains
over tags. My understanding is that those gains were eliminated (or
reduced to the point of insignificance) in CF 6.x and 7.x. Here are

You can't just merge two XML documents together in CF the way you are
doing it. Spike has an excellent explanation here:

Is the XMLTransform() throwing the "content in prolog" error or is the

It looks like your output from the XMLTransform() might not be valid

I'm not exactly sure what you are asking. If you are asking "How do I

XSLT can be a little bit tricky to get your head around if you are new

One area where we found significant improvements by moving code from

This is really helpful! I will use something like this in order to
send multiple statements (like 1000 inserts, updates, or deletes) to the
