in reply to Link Parser, something to be desired?

Hi!

It seems doesn't work.

my $regex = "href\s*=\s*\"?.*\"";

I think it should be 

my $regex = qr{href\s*=\s*".*?"};

Note qr// and question mark position. So perhaps your code should look something like this: 
use strict;
use warnings; # this is also useful

my $regex = qr{href\s*=\s*".*?"};
my $sub = "href=\"#\"";

while(<DATA>){
    s/$regex/$sub/g;
    print;
}

__DATA__
afjalsdfj href="asfasdfa" afdsas href="akjshfakjsd"
href = "ajsfhaklj"

Update: and here's another approach using HTML::Parser: 

use strict;
use warnings;
use HTML::Parser;
use HTML::Entities;

my $html = join '', <DATA>;
my $p = HTML::Parser->new(
    default_h => [ sub { print shift }, 'text' ],
    comment_h => [""],
    start_h => [ \&start, 'tag,attr,attrseq,text' ]
);
$p->parse($html);

sub start {
    my ( $tag, $attr, $attrseq, $text ) = @_;
    unless ( exists $attr->{href} ) {
        print $text;
    }
    else {
        $attr->{href} = "#";
        print "<$tag";
        print " $_=\"", encode_entities( $attr->{$_} ), '"' for (@$att
+rseq);
        print ">";
    }
}

__DATA__
<html><body>
<h1>title</h1>
<a href="foo" class="class">link</a>
<p>some <a href="link">text</a> and <a href="another_link">more</a>
</body></html>
