I have a custom render where I need to query a couple different datasources, then combine that xml and merge with the pdf to display. Basically I need to pre-populate from two different sources. I'm having a brain freeze here and not sure of the best way to merge the XML back into one xml variable to merge with the form. Should I use XSL transform? I know how to reference xml files in xsl transforms, but how do I reference the xml variables I use for the results from the query multiple to xml? I have 2 XML variables and need to have only one when merging with the form.
