[basex-talk] replace expression

I am trying to substitute the content of an element with its content in a document, using copy $e := doc("document") modify ( for $x in $e//C return replace node $x with $x/text() ) return $e Although this seems to be a plain query, it never ends when launched, so that I am forced to quit BaseX. Any suggestions? Thanks! PS: my document contains a lot of the elements I want to change. I do not know whether there si an "easy" alternative to "copy"/"replace" Best, Joseph
