Rather than risk breaking existing functionality by rewriting the
length limiting filter, why not just create a new filter to strip
HTML from the string?
With that, you could then create a filter pipeline that looks
something like the following:
[filter op="strip html2text strip_html decode_entities 20. encode_entities"]
New filters can be placed in the "code/Filter" directory instead of
I imagine that the strip_html filter could be very simple, and would
probably just look something like "s:<[/\w].*?>::g".
That's probably what I'd try if faced with a similar problem.
Either that, or create a new "limit_html" filter that does everything
in one hit - without disturbing existing code. For example:
Electric sheep say "Fooo <i>Baaaaaaa</i>"
Which, in theory, could make "Electric sheep say "Fooo Baaaa".
You could code it to adjust, and include, the italic tag span if you
really need that functionality.
