Thanks, this looks more powerfull. Support CSS, XPath and XQuery. Maybe I could learn a bit of XQuery when I have a use case for it :)
(: XQuery comments are marked by mirrored smilie faces, like this. :)
An empty query is not valid. There needs to be something besides the comment
<users>
{
for $user in //users
let $comments = //comment[@uid = $user/@id]
where count($comments) > 0
order by $user/lastName, $user/firstName
return <user id="{ $user/@id }">
<name>{ concat($user.firstName, " ", $user.lastName) }</name>
<comments count="count($comments)">
{
for $c in $comments return <comment id="{ $c/@id }" />
}
</comments>
</user>
}
</users>
