I understand the unreasonableness of many requirements but I don't
understand what's happening here. Surely if you transform an XML document to
another XML document then any ampersands in the output will still be escaped
on serialisation?

Subject: [xsl] Problem with ampersands
Date: Tue, 26 Sep 2006 10:03:30 +0800
Hi,
I have this requirement from a client to retain all the entity references
in their xml files after transformation so what i did was collect all the
entities in the DTD and then created a character-map for single-character
entities. For multi-character ones, i created a used a function to search
and replace all occurrences in a text node. My problem is when i use the
function and return the value, xslt escapes the ampersand symbol as &
and i don't know how i can unescape it without unescaping the real
ampersand character.
Below is a snippet of my stylesheet and the output that i'm getting.
XSL:
