Question

I want to get the search box from this site, I use php regular the form part, but there still has many other html code in it. So how to remove them and just get a pure search box? Thanks.

<?php
$str = file_get_contents('http://bingphp.codeplex.com');
preg_match_all('~<form.+</form>~iUs', $str, $match);
var_dump($match);
?>

Answer 1

Should use DomDocument parser ?

$dom = new DomDocument;
libxml_use_internal_errors(true);
$dom->loadHTMLFile('http://bingphp.codeplex.com/');
$nodes = $dom->getElementsByTagName('form');
foreach ($nodes as $node)
{
  echo simplexml_import_dom($node)->asXML();
}
