[basex-talk] How to update a XML-file from itself?

Hi, Can anyone help me with this casus? I want to update XML-source: $a, by inserting the content of XML-element: $b, a sub-element of $a, into XML-element: $c, also a sub-element of $a. The relative path from $b to $c is known. See attached example: the problem is that the update works on a copy of $a and that the destination-element: $b/parent::*/default/text1, is actually an element of the original $a. How can I make it point to the corresponding element in the copy? Any suggestions? Thanx in advance, Rob Stapper --- Dit e-mailbericht bevat geen virussen en malware omdat avast!
