Re: Removing HTML tags from a string

Rather than removing the tags, you could easily use HTML entity encoding to make them appear literally as the user typed them:

      use HTML::Entities;
      print encode_entities("<b>hi</b>");

&lt;b&gt;hi&lt;/b&gt;

wouldn't just a simple `foreach (@line){ $_ =~ s/\</\&lt\;/g; $_ =~ s/\>/\&gt\;/g; }` [download] work just as well? John J Reiser newrisedesigns.com	[reply] [d/l]

Well, if that's what I meant, I probably would have typed something like this: `for (@line) { s/</</g; s/>/>/g; }` [download] But to answer your question: It's actually less brain drain to use a tested and complete module than to write equivalent code -- especially when the code isn't equivalent at all.... Or were you under the impression that the only dangerous characters for HTML rendering are "<" and ">"? -- Chip Salzenberg, Free-Floating Agent of Chaos	[reply] [d/l]
