Who says you need UBot to run basic scraping tasks? Here’s a trivial script that scrapes centurian.org. It’s unoptimized (i.e. slow as fuck) but it still does a great job.

<?php
// DOMDocument()s throw shitty warnings for broken HTML
ini_set('display_errors', 0); 

$scrapeURL              = 'http://www.centurian.org/popular-proxies/?start=';

$startIndex             = 0;
$stop                   = FALSE;

while (!$stop) {
		//create the DOMDocument
        $dom = new DOMDocument();
        $stop = TRUE;
        if ($dom->loadHTMLFile($scrapeURL . $startIndex)) {
        		//get all links from the page
                $list = $dom->getElementsByTagName('a');
                for ($i = 0; $i < $list->length; $i++) {
                        $proxy = $list->item($i)->textContent;
                        //we only want the links that have "http://" in anchor
                        if (strpos($proxy, 'http://')!==FALSE) {
                                print $proxy."\r\n";
                                $stop = FALSE;
                        }
                }
        }
        $startIndex += 32;
}

?>

Usage:

pigpromoter@pleech:~/scrapers/centurianDOM$ php ./centurianDOM.php > proxies.txt
pigpromoter@pleech:~/scrapers/centurianDOM$ cat ./proxies.txt | wc -l
6277

… or simply put it in your htdocs and fire it up through the browser.

As I said, the script is trivial, but it’s a good way of seeing how DOM works. Enjoy!
