Just an example (and an agreement that I think scripting XQuery is a great
thing. but there is more then one way to skin the cat ).

Original Query fragment:

=======================
declare variable $docs :=
   collection(iri-to-uri(concat('file:///xmlsource',
'?recurse=yes;select=*.(xml);parser=org.apache.xml.resolver.tools.ResolvingXMLReader')));

for $topic in $docs
where ($topic//*[contains(@href, '\') or contains(@conref, '\')])
return
   base-uri($topic)

========================


c) xmlsh
Its not as verbose as other scripting languages integrating with xquery, and 
about as efficient as anything within xquery.

PASS=()
for file in $(find /xmlsource -name *.xml) ; do
    xread doc < $file
    <[ test1_xquery_expr ...  $doc ]> && PASS+=<[ base-uri($doc) ]>
    <[ test2_xquery_expr  $doc   ]> && PASS+=<[  base-uri($doc) ]>
...
done

echo Passed Tests $PASS

I wont try to write this in xproc.
