Can't you modify your external function to pass the string through an
XML parser, and supply a document node rather than a string to XQuery?

Or, equivalently call an XML parser as an external function. In saxon
for example you could use
saxon:parse($string)
to return the nodes resulting from parsing the XML in the string.
