PHP Simple HTML DOM Parser find string

Question

I am using PHP simple DOM parser but it does not seem to have the functionality to search for text. I need to search for a string and find the parent id for it. Essentially

Answer 1

$html = file_get_html('http://www.google.com/');

$eles = $html->find('*');
foreach($eles as $e) {
    if(strpos($e->innertext, 'theString') !== false) {
        echo $e->id;
    }
}
