MySQL Question

PHPCrawl with simplehtmldom to parse data

I'm trying to use PHPCrawl to crawl and collect URL(s), then feed to simplehtmldom to pull the required data from the html and store in a mysql database. Right now I am getting the error


Fatal error: Call to undefined method simple_html_dom::find() in
/home/content/54/11109254/html/PHPCrawl_081/skunktest.php on line 44


Can anyone help out with what I've done wrong, and maybe glance over and see if I have any other hurdles ahead of me?


// Inculde the phpcrawl-mainclass

// Include Simplehtmldom

// Extend the class and override the handleDocumentInfo()-method
class MyCrawler extends PHPCrawler
function handleDocumentInfo($DocInfo)

// Just detect linebreak for output ("\n" in CLI-mode, otherwise "<br>").
if (PHP_SAPI == "cli") $lb = "\n";
else $lb = "<br />";

// Print the URL and the HTTP-status-Code
echo "Page requested: ".$DocInfo->url." (".$DocInfo->http_status_code.")".$lb;

// Print the refering URL
echo "Referer-page: ".$DocInfo->referer_url.$lb;

// Print if the content of the document was be recieved or not
if ($DocInfo->received == true)
echo "Content received: ".$DocInfo->bytes_received." bytes".$lb;
echo "Content not received".$lb;

// Now you should do something with the content of the actual
// received page or file ($DocInfo->source), we skip it in this example

$result = $DocInfo->url;

Try this

$html = new simple_html_dom();

if($html && is_object($html) && isset($html->nodes)){
