I was easily able to complete this via a service task. I had code to do this already.

However I was attempting a proof of concept where an editor could generate a script task to retrieve a value from a block of xml via xpath search without developing a delegate and using only javascript. All my attempts to accomplish this task failed due lack of access to libraries, and lack of knowledge on javascript. I was unaware that I could call out java libraries in javascript.

One thing that I didn't try was to see if jQuery was available to javascript tasks. That probably would have been another method that would ease things.
