Just use ExecuteScript and the Groovy MarkupBuilder/StreamingMarkupBuilder
APIs. There is plenty of documentation on the latter out there with good
samples. Depending on how much XML data there is, you'll probably need to
use the StreamingMarkupBuilder and have it write to a temp file. One
caveat: those two Groovy classes have their own use cases and slightly
different APIs that prevent you from copying and pasting code for one and
using it on the other.
