How to Parse HTML in PHP to Extract Text Between Headings Without Regular Expressions?

PHP Parse HTML Code

Q: How do I parse HTML code stored in a PHP variable to extract the text between headings, without using regular expressions?

A: Use PHP Document Object Model:

$DOM = new DOMDocument;
$DOM->loadHTML($html);
$items = $DOM->getElementsByTagName('h1');
for ($i = 0; $i < $items->length; $i++)
    echo $items->item($i)->nodeValue . "<br/>";

If you want the content between headings, use this regex:

echo preg_replace("#<h1.*?>.*?</h1>#", "", $html);
