Hi Christian,

thanks for the hint. I'll try it after updating my system. Looks promising.

Cheers, Günter

Hi Günter,

The chaining of update operations just got easier with the extension of our "update" operator [1,2]. I’d be interested in your feedback.

Cheers, Christian

Hi all, hi Christian,

for my queries I have to modify some legacy xml-documents. The copy/modify/return-expression works fine with one for-clause. But I have to modify different elements. I can't figure out, how to chain the for-clauses.

Working Example:

copy $doc := $document modify ( let $first_elements := $doc//element-name for $element in $first_elements let $target := $element/@target let $htm_anchor := substring-after($target, '#') return replace value of node $element/@target with 'xyz' || $htm_anchor ) return $doc

This is working for one for-clause. But I have to do a lot more with different elements for example:

let $second_element := $doc//element-name-second for $ele in $second_elements let $... return ...

The returning document should contain all modifications. How can I chain the for-clauses inside modify?

Thanks for a hint in advance.

Günter
