Re: Strip specific html sequence

I should add that the match is not at the beginning of a line. When used in the variable, it 'matches' many random line start characters, but ignores the match itself! A typical line of HTML I want to target is:

</div></div><div><div class="blue"></div></div>

The desired result is:

</div></div>

Break it down to just the lines you want and fix those in isolation. SSCCE: `use strict; use warnings; use Test::More tests => 2; my $input = '</div></div><div><div class="blue"></div></div>'; my $expected = '</div></div>'; my $remove = '</div><div><div class="blue"></div>'; like ($input, qr/$remove/, 'Match found'); # Just for illustration $input =~ s/$remove//; is ($input, $expected, 'Strip successful');` [download] Searching has suggested this is silly to try without a cpan solution Quite right. If you start to attempt to parse HTML in this fashion you are starting down a long and slippery slope which ends in the belly of the grue. Recant now while there is still time.	[reply] [d/l]

use strict;

use Test::More tests => 2;

my $input    = '</div></div><div><div class="blue"></div></div>';

like ($input, qr/$remove/, 'Match found');    # Just for illustration
$input =~ s/$remove//;
is ($input, $expected, 'Strip successful');

Quite right. If you start to attempt to parse HTML in this fashion you are starting down a long and slippery slope which ends in the belly of the grue. Recant now while there is still time.
