Daniel, It was kind of you to respond, and your response was a model of clarity. You correctly surmised from my awkward framing of the question, that what I wanted was a list of sibling elements between one named anchor and the next. My problem was, in part, that I still don't think in terms of functional programming, thus, the function defs you proposed are very helpful models for me. I do, however, still need to work out how to make is_anchor() return true only if the anchor name attribute satisfies a given regex. Starting with your model, I'm sure I'll be able to figure this out.
Thanks so much for your time!
