To strip html add the following filter to interchange.cfg:

GlobalSub <<EOR
sub strip_html {
        BEGIN { 
                package Vend::Interpolate;
                $Filter{striphtml} = sub {
                                                my $val = shift;
                                                $val =~
s/<(.|\n)+?>//gis;
                                                return $val;
                                        };
        }
}
EOR

And call it like this:  [filter striphtml]<a href="test">Testing the
striphtml filter</a>[/filter]

Not as difficult as the first example I saw on google :)  This one will
remove all text between < and >.  There is probably a better way to
handle the regex in the case that <> appear outside of an html tag.
I'll work on a strip ITL as well.  IC team, if you'd like to add this to
the default filter list please do.

Thanks,
