Ignore that - I hadn't grasped the problem. Sorry for the general confusion.
If the web service is returning valid xml, then there shouldn't be a
problem with xdmp:unquote(). The quotes should be "e; in the actual
string from the web service. You should also be able to use the
xdmp:document-get 'format' option to specify xml in the first place.
You should only need '&quote;' if you're trying to test sample
output in cq (or another ad-hoc query evaluator). And for test cases
like that, you should be able to modify the string as needed.
Here's a replace() that does work, but it's problematic. As far as the
evaluator and the XQuery data model are concerned, there is no
difference between <p>"</p> and <p>"e;</p>. So the regex has to look
for other clues to figure out which one you want to replace.
let $ex as xs:string :=
'<exception message="One of
''{"http://www.w3.org/1998/MathMathML":semantics}'' is
expected."/>'
let $ex := replace($ex, '\{"', '{&quot;')
let $ex := replace($ex, '":', '&quot;:')
return xdmp:unquote($ex)
=>
<exception message="One of
'{"http://www.w3.org/1998/MathMathML":semantics}' is expected."/>

Wyatt,
Try using a computed constructor.
let $message := 'this is a string with a "quote" inside it'
return element exception {
attribute message { $message }
}
=>
<exception message="this is a string with a"quote" inside it"/>

Hi Andrew,
Thanks for the suggestion... I agree that's the issue, but I'm not
quite sure how to work around it. I've tried the following to no avail
- how do I replace the& with&? (unfortunately, I can't change the
value of $ex, this comes from web-service call)...
let $ex as xs:string := '<exception message="One of
''{"http://www.w3.org/1998/Math/MathML":semantics}'' is
expected."/>'
return
xdmp:unquote(
replace($ex, "&","&")
)

Always gives error "SystemID: XDMP-DOCSTARTTAGCHAR: xdmp:unquote("<exception

character "/" in start tag at line 1"
That's because" gets resolved to " when the query is parsed, so
your variable $ex becomes:
<exception message="One of '{"http....
..you can see the double quotes that are causing the exception when
you try and parse that as XML using xdmp:unquote.
One answer is to double escape them:
message="One of ''{&quot;
..then after the query is parsed you are left with """ as expected.
