[jdom-interest] Finding syntactically-related children and parent Elements in XHTML

[Costas Mantratzis]

Yes, absolutely, that would work.

However in this case I would have to be the one to "teach" the system
(through the filter) what schema to follow.

I was wondering if such a schema understanding was already built-into one of
the many (x)HTML parsers out there and exposed through an interface for
validation.

I guess that beyond elements of tables and lists (and perhaps a few other
examples of explicit element relations that I might be forgetting right now)
there isn't a great need for such a feature since most other elements can
legally exist in a number of hierarchy combinations (i.e. an anchor A can
exist within a TD but also within a P on its own, outside a table)...
