Have you investigated `findf-txexpr` and `findf*-txexpr` in the `txexpr` module?

[pollen] Composing select functions is awkward

[Shrutarshi Basu]

Hi all,
Here is a simple workflow I'm trying to implement: (1) get a tag's contents
using `select-from-doc` and then (2) get all instances of a particular tag
from the contents returned by (1) using `select*`. However, this doesn't
work because `select-from-doc` returns a list of X-expressions, while
`select*` requires a txexpr. It would be great to have some functions that
allow us to easily select txexprs from within txexprs.

Thanks,
Basu
