Something like:
Hello there
in other words : span#myId.class1.class2

is there a way to perform this with DOMElement ?

thanks

above text not working in windows 7. it occurring this error

Catchable fatal error: Object of class DOMElement could not be converted to string in /var/www/websites/shabbonacreekrv/shabbonacreekrv.com/www/html/vehicle.php on line 65

to test it…

Warning: domdocument::domdocument() expects parameter 2….

Fatal error: Call to undefined method domdocument::loadHTML()

I am using php 5.2.x + WAMP

php_domxml extension is enebled.

What is wrong in my code ?? $html has html content.. i did not paste it here. its the same as your example.

$dom = new DOMDocument(‘1.0′,’utf-8’);
$dom->loadHTML($html);
$dom->preserveWhiteSpace = false;
$tables = $dom->getElementsByTagName(‘table’);
print_r($tables);

thanks for the feedback, shall update the post soon.
