extract information: parametric operetor

daddou20012

I have a problem for extracting text from a document using the operator extract information, when I want to have parametric xpath that contains a call to a macro effect like this:
/ / *[@ class = 'contentheading' and contains (.,. +% {macro}. +)]

But this is not functional %{macro}Since runnig is not replaced by its value

any one can help  ???

thanks you in advance

Actually it works inside the query expression (see example below). Do not forget the quotes and take care that you expression is grammatically correct .
