Sure ... review what I said earlier:
To look anywhere below oneself, use ".//" ... to look for any element use
"*" ... to filter only those elements that do not have any element,
comment or PI children (i.e. lowest in the hierarchy), use the predicate
"[not(node())]" and to check for a particular attribute existing use the
predicate "[(_at_)minimum]".
Just skip the predicate that qualifies the node as being at the bottom, and
you end up with:
test=".//*[(_at_)minimum]"
as the boolean test of any elements with the attribute. Alternatively
since all you are doing is testing you could just have:
test=".//*/@minimum"
to address the attributes, but the way you worded it you wanted to address
the elements that have the attribute.
How much reading of XPath have you done? I would recommend reading the
specification or one of the many resources that can help you understand the
composition of location path expressions.
