php: Parse string from html

Question

I have opened an HTML file using

file_get_contents(\'http://www.example.com/file.html\')

and want to parse the line including \"ParseThis\"

Answer 1

Since it is the first h1 tag, getting it should be fairly trivial:

$doc = new DOMDocument();
$doc->loadHTML($html);
$h1 = $doc->getElementsByTagName('h1');
echo $h1->item(0)->nodeValue;
