Inserting and removing data with QXmlQuery

piemur2000

Hello,

I would like to know if it is possible to insert/modify/remove data with an XQuery using QXmlQuery?

I found an "exemple":http://www.xmlmind.com/tutorials/XQueryUpdate/index.html of XQuery updating some data with the following query but I am not able to run it:
@for $idattr in doc("data.xml")//ITEM/@Id (: selection :)
return (
delete node $idattr, (: update 1 :)
insert node <NID>{string($idattr)}</NID> (: update 2 :)
as first into $idattr/..
)@
I have the following error :
syntax error, unexpected node, expecting )

If it is not possible to use insert or delete how I am suppose to modify the content of a document?

Thanks
