[basex-talk] xquery and hash:md5

This may be a question better suited for an xquery forum but I'll start here since I'm using basex:

Can someone suggest why I'd be getting the same result for the hash call even though the content of $r should be changing?

let $reps := fn:collection($coll)/Rep for $r at $lcv in $reps let $hash := xs:hexBinary(hash:md5(fn:string($r))) return <hash i="{$lcv}">{$hash}</hash> };

Please let me know if I should post this elsewhere (and please include where).

Thanks in advance for any suggestions.
