php - check loadHTMLFile url exists and if it has a div in it, if not, do nothing -

i trying detect couple things url.

1. is valid

2. does have specific div in it

   $url = 'http://www.google.com/aasdsasdfafddsgsagf'; $dom = new domdocument; libxml_use_internal_errors(true); $request = $dom->loadhtmlfile($url); $domxpath = new domxpath($dom);  $title = $domxpath->query("//span[@class='bluebar']")  if(!$request || $title->length == 0){     echo 'failed!!'; } 

i trying conditions:

if page loads , does not have div - nothing.

if page not load - nothing.

right getting error stops comes after running properly.

error:

warning: domdocument::loadhtmlfile(http://www.google.com/aasdsasdfafddsgsagf): failed open stream: http request failed! http/1.0 404 not found in... 

i still echo 'failed!!'.

please help!!

if understand question correctly, problem can solved suppressing warning. can done affixing $dom->loadhtmlfile($url) error control operator @.

$request = @$dom->loadhtmlfile($url); 

in example there missing semicolon after setting $title. causes php parse error. code want:

$url = 'http://www.google.com/aasdsasdfafddsgsagf'; $dom = new domdocument; libxml_use_internal_errors(true); $request = $dom->loadhtmlfile($url); // $request === false $domxpath = new domxpath($dom);  $title = $domxpath->query("//span[@class='bluebar']");  if(!$request || $title->length == 0){     echo 'failed!!'; }
