Your final choice was correct :-)

Thanks Adam, as you said it was quite easy to modify to get what I need.
On a related note. When I called from IE the results weren't displayed
nicely formatted although a quick 'View Source' confirmed that
everything was OK. I noted that the MIME type returned was tex/html,
so I started experimenting with various ways of setting this. I tried
using :-
response:set-header("Content-Type", "application/xml;charset=UTF-8")
but couldn't get this to work (actually I wasn't 100% sure where to
put this in the XQuery ?? I kept getting errors like 'Variable
$response is not bound to a Java object' ..
I then found a note from you about setting the param
dynamic-content-type in server.xml. I assumed this meant here :-
<rest enabled="yes" context="/*">
<!--
Special params: set form-encoding and container-encoding. If they
are set to different encodings, eXist may need to recode
form parameters.
-->
<param name="form-encoding" value="UTF-8"/>
<param name="container-encoding" value="UTF-8"/>
<param name="dynamic-content-type" value="yes"/>
but again this didn't seem to have any effect ??
Finally I tried the XQuery option :-
declare option exist:serialize "media-type=application/xml";
and this DID seem to work.
Was this the right choice ?
Should the other methods have worked ?
Thanks
Fraser
