Counter Variable in XPath name?

Description description

Environment

Issue/Symptoms

Is it possible to use a counter variable like the one given below in an xpath name?

<set expr=”@counter” xpath=”/test/element[ @counter] ”>

Trying this shows an error with the @counter in the bracket in the xpath, but using a number instead <set expr=”@counter” xpath=”/test/element[ 1] ”> works just fine.
Is there a function for adding to a DOMDocument Element, either by an append function or by using the above-mentioned counter variables?

Resolution resolution

xpathExpr will work.
