greetings,
I use something similar to filter the HTML altogether. Just for that
purpose.
MACRO escape( text )
BLOCK;
GET text.replace('<(/?)([biau])>', '').replace('<a href=', '').replace('\>',
'');
END;
But I only allow bold, italic, underline, and links, to be there in the
first place.
It's used like so:
[% escape(temp.var) | truncate(50) %]
Also I attempt to filter html out of some sections altogether. However my
regexe isn't the best, so I just filter things I feel could impact page
layout and design.
style, iframes, headers and images....
stripHTML => sub {
(my $r = shift) =~ s/[\r]/<br \/>/g;
$r =~ s/(<[^<|>]*?)(style=".*?")|/$1/g;
$r =~
s/(<[^<|>]*?img.*?\/?>|<[^<|>]*?iframe.*?<\/iframe>|<[^<|>]*?style.*?<\/style>|<h[0-9]>.*?<\/h[0-9]>)*?//gx;
return $r;
},
I pass it along as a temp var. Then use in Template like so:
[% stripHTML(user.input) %]
Hope this helps. :\
PS- Any improvements to my regexe are graciously accepted :)
