Hi Lanz,
Be carefull with 'catch($e) { }', I recommend adding an xdmp:log($e). You might
be missing an important warning here.
Can you also tell us exactly how you are verifying "collection-last"? Make sure
to check in a separate transaction.
Kind regards,
Geert

> xdmp:document-remove-collections not working
>
> Hi all,
>
> I have an issue with xdmp:document-remove-collections, the
> way I use this function does not work.
> Here is my code explanation :
> 1- I want to move XML documents from one input directory to
> another one (in reality, delete and recreate document)
> 2 - with xdmp:document-insert I add some collections to the
> new document, 3 collections related to the date and one other
> which flags the document as the last one ("collection-last")
> 3- I need to keep only one document in the collection
> ("collection-last") : each time I "move" a document (see 1-)
> I remove all document from ("collection-last") and then I set
> ("collection-last") to the processed document.
>
> But it seems that I can't remove all documents from
> ("collection-last"), there is no error but it does not work at all :
> all document keep this collection
> Help is appreciated., Thanks !
