Variable Creator

Hi

I want to use the Variable Creator node, to create variables that depend one on another. E.g. I want to build an XPath where the value of an attribute shall be given from the outside. So I would like to create a variable containing a placeholder string and insert that into the other variables such that I later can replace the placeholder with the actual value along the line

Is that possible? I will try to cough up a workaround.

Cheers

Thiemo
