Hi, XQueriers:

   I have an XQuery as in the following:

let $ad := fn:collection("xmldb:exist://db/cbml")
let $volume := $ad//seriesStmt/idno[@type='volume'][1]
let $issue := $ad//seriesStmt/idno[@type='issue'][1]
let $journal := $ad//seriesStmt/title[@level='journal'][1]
let $ad2 := $ad//ad/head[contains(., 'muscle') or contains(., upper-case('muscle'))]
let $sorted_result:=
for $doc in distinct-values($ad2)
order by $doc
return $doc
for $r at $count in $sorted_result
let $nodes := $ad2[. = $r][1]
return
<ad>
<statistics>
Showing Result: {$count} / {count($sorted_result)}
</statistics>
<source>
<journal>{data($journal)}</journal>
<publication_information>Volume {data($volume)[1]}, Issue {data($issue)}</publication_information>
</source>
{$nodes}
</ad>

Right now, I have a sample entry as in the following:

<ad>
<statistics> Showing Result: 1 / 2</statistics>
<source>
<journal>My Journal My Journal My Journal My Journal My Journal My Journal My Journal My Journal </journal>
<publication_information>Volume 1 , Issue 2 4 1 3 5 6 7 </publication_information>
</source>
<head rend ="bgblack">
<emph rend ="red">FREE MUSCLE Secrets</emph>
</head>
</ad>

What I want:
<ad>
<statistics> Showing Result: 1 / 2</statistics>
<source>
<journal>My Journal</journal>
<publication_information>Volume 1 , Issue 1</publication_information>
</source>
<head rend ="bgblack">
<emph rend ="red">FREE MUSCLE Secrets</emph>
</head>
</ad>

How much would I have to adjust my XPath expression to return something like above?
Any help is appreciated.
