[ACCEPTED]-How can I strip HTML in a string using Perl?-strip

Assuming the code is valid HTML (no stray 3 < or > operators)

$htmlCode =~ s|<.+?>||g;

If you need to remove 2 only bolds, h1's and br's

$htmlCode =~ s#</?(?:b|h1|br)\b.*?>##g

And you might want 1 to consider the HTML::Strip module

From perlfaq9: How do I remove HTML from a string?

The most correct way (albeit not the 19 fastest) is to use HTML::Parser from CPAN. Another 18 mostly correct way is to use HTML::FormatText 17 which not only removes HTML but also attempts 16 to do a little simple formatting of the 15 resulting plain text.

Many folks attempt 14 a simple-minded regular expression approach, like 13 s/<.*?>//g, but that fails in many 12 cases because the tags may continue over 11 line breaks, they may contain quoted angle-brackets, or 10 HTML comment may be present. Plus, folks 9 forget to convert entities--like < for 8 example.

Here's one "simple-minded" approach, that 7 works for most files:

#!/usr/bin/perl -p0777

If you want a more 6 complete solution, see the 3-stage striphtml 5 program in http://www.cpan.org/authors/id/T/TO/TOMC/scripts/striphtml.gz .

Here are some tricky cases 4 that you should think about when picking 3 a solution:

<IMG SRC = "foo.gif" ALT = "A > B">

<IMG SRC = "foo.gif"
 ALT = "A > B">

<!-- <A comment> -->

<script>if (a<b && a>c)</script>

<# Just data #>

<![INCLUDE CDATA [ >>>>>>>>>>>> ]]>

If HTML comments include other 2 tags, those solutions would also break on 1 text like this:

<!-- This section commented out.
    <B>You can't see me!</B>

You should definitely have a look at the 4 HTML::Restrict which allows you to strip away or restrict 3 the HTML tags allowed. A minimal example 2 that strips away all HTML tags:

use HTML::Restrict;

my $hr = HTML::Restrict->new();
my $processed = $hr->process('<b>i am bold</b>'); # returns 'i am bold'

I would recommend 1 to stay away from HTML::Strip because it breaks utf8 encoding.
