If you are just doing an equality match you can use the "=" operator (which will operate over sequences and return true if any member is equal: $file-type = $file-types If you really mean fn:match, then you need to run the loop yourself: let $nothing := fn:empty( for $f in $file-types return if (fn:matches($f, $file-type)) then "ok" else ()) If there is any match the sequence given to fn:empty will be non-empty so $nothing is false. //Mary _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
