Hi Folks,

The variable $A contains an element.

The variable $B contains an element.

I need an XPath expression that determines if $B is not contained in $A.

This XPath expression seems to work:

not(index-of($B/ancestor::*,$A))

but that seems awful, i.e., not straightforward, convoluted, and probably inefficient.

If you have (element) nodes I fail to see how the index-of function helps that works on sequences and uses "eq" comparison helps to check containment? Don't you need https://www.w3.org/TR/xpath-functions/#index-of-node?
