Re:  Issue with entities in XML document
presumably your extension function is _serialising_ the xml content as
a string containg XML markup, which you don't want. you just want it to
return a string.




<description>Hansel &amp; Gretel</description>

so the content of that element is a string of length 15
"Hansel & Gretel"

If you need to write that string to an _XML_ document/file/stream then 
you need to write out the & as &amp;, and that's what presumably
the strringwriter is doing.

but you are not writing to a linearised XMl document you are calling an
XPath extension function and writing the string straight back into an
XPath value, so the value of the element you create is
"Hansel &amp; Gretel"
and when the element is serialised as the result of the XSLT
transformation, you get
"Hansel &amp;amp; Gretel"

So I suspect that the problem is with your extension function returning
XML markup rather than just a string (if it just returns a single
element value) or an in-memory tree of some sort (if it is constructing
an element tree).

Of course details of how extension functions work and how java trees map
to XPath trees depend on the processor you are using.
