[xquery-talk] using a context node in a for loop

Hi, (more newbie questions)
Should the function below work? I want to define a node and use it to
base the attributes off of. In the for loop (unlike the if..then
statement), it seems I need the return statement, otherwise I get an
error saying "unexpected token 'doc'". But, as written, I get an error
"undefined context sequence for 'attribute::label'". I have also tried
removing the parans grouping the li.
Also, notice in the for loop I am using a function to get the list to
iterate through. Should that be a variable - or - does it only get
evaluated once?
Here is the function:
declare function local:display-user-groups() as element()* {
for $user-group in xmldb:get-user-groups($user)
return
doc(concat("projects/", $user-group, "/project.xml"))/*/
(
<li>
<a href="#"
onclick="submitForm('{@id}', '{@db-ref}')">
{string(@label)}
</a>
</li>
)
};
thanks,
-Rob
