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

Hi,

Here is another thingy I tried but again: no cigar.

The problem would be solved if I could determine the absolute path to an element-variable: $c

Hi Rob,

I didn’t find variable $c in your example, but the following modification might give you the correct result:

let $update.processor := function($a, $b) {

($a update replace value of node ./default/text1 with ())

update insert node $b/string into .//default/text1

}

or (depending on what you plan to do):

let $update.processor := function($a, $b) {

($a update insert node $b/string into default/text1)

}

As you already observed, it is only possible to update nodes that have been copied by the 'update' keyword.

Hope this helps,

Christian

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
