From 896e4566c5f976965a803a55488e2a50691f2552 Mon Sep 17 00:00:00 2001

Subject: [PATCH] irspy_xpath_context() may now take a textual XML record
 instead of a 	DOM tree. dom_add_element() now correctly
 inserts a new _element_ with specified 	value,
 rather than just inserting the value itself. Slightly
 changed debugging output for modify_xml_document() and 
 dom_add_element().
