vagabonding electron,

Just another way to look at the problem: 

#!/usr/bin/perl
use strict;
use warnings;

my $start = 0; my $h2 = 0; my $keyword = ""; my $end = 0;

while ( my $Content = <DATA> )
{
    chomp( $Content ); my $content = lc( $Content );

    if ( $start == 0 )
    {    $start = index ( $content, '<div id="bodyContent">' ); }
    else
    {    if ( $h2 == 0 )
        {    my $h = index ( $content, '<h2>' );
            if ( $h >= 0 )
            {    $h2++; $keyword = substr( $Content, $h+4 ); my $tmp =
+ lc ( $keyword );
                $end = index ( $tmp, '</h2>' );
                if ( $end >= 0 )
                {    $keyword = substr( $keyword, 0, $end );
                    print "$keyword\n\n";
                    $h2 = 0; $keyword = "";
                }
            }
        }
        else
        {    $end = index ( $content, '</h2>' );
            if ( $end >= 0 )
            {    $keyword .= substr( $Content, 0, $end );
                print "$keyword\n\n";
                $h2 = 0; $keyword = "";
            }
            else
            {    $keyword .= $Content; }
        }
    }
}

When working with HTML, you can't be sure that everything is lined up correctly. Notice I put some end-of lines before the last </h2> just to make sure it could handle multiple lines.

Another approach would be to process the HTML and extract the <h2>...</h2> into an array and then process the array to eliminate span, fonts, etc after you have complete information in each element of the array.

Good Luck!
