Currently scraping stops on the first regex match, and the matched subpatterns are returned as the result of scraping.

For some scraping scenarios, it would help keep regexes simple if a regex could be flagged as a filter; on a match, the matched subpatterns are passed on to subsequent regexes as their input text rather than being returned as a result.

For example, consider a UK Freeview title continuation:

title: This Title continues...
summary: ...into the summary. Which has further text.

When processing the summary in this case, it simplifies regexes considerably if an early filter regex can remove "...into the summary. " from the text to be considered by subsequent regexes looking for subtitles etc.

(I have a change in preparation that does this).
