No, there's no simple way to access the element. Filters, with a few
exceptions, are meant to operate on strings, not on the parse tree. They
are usual meant as a simple way to transform the output. I.e., they are
intentionally dumbed down.

You could however, use the parse-tree filter to modify the parse tree
before export.
