XPath query difficulty...

O

oopsatwork

I'm trying to construct an XPath and it is giving me trouble. I have
an XML that contains a "Routine". The routine contains "Steps". The
steps have different types. Some types of steps have more steps
contained within them (substeps). I want to get a list of all of the
steps in a routine, including any substeps...but excluding substeps
that occur in a particular type of step ("Subroutine").

Below is a simplified example XML. The query I envision would return
all of the steps in the routine, including substeps found in the
"Loop" step type and "Condition" step type...but NOT including any
steps that are anywhere within a "Subroutine" step.

Any thoughts? My sincerest thanks in advance!

//Step[not(ancestor::Type[. = ' Subroutine '])]

I would think, this should work (not tested, though)

//Step[not(ancestor::Step[Type = 'Subroutine'])]
