I cannot get my head around what you are trying to say...but...there is no need to remove the <span> and <div> tags any more than you do any of the rest of the page's HTML.

use strict;
use LWP::Simple;

my $html = get("http://example.com");

while ($html =~ /<td>(.+)?<\/td>/gc) {
    print $1."\n";
}

This will fetch a webpage and extract and print the content of every <td> tag. No need to strip anything out first or to make more than one request to the webserver.
