regex - PHP Regular express to remove <h1> tags (and their content)

Question

Hay, i can't seem to find any regular expressions online to remove

<h1></h1>

tags (and their content).

Anyone lend a hand on this and help.

Answer 1

Don't use a regex, use a tool like PHP Simple HTML DOM.

// Construct dom from string
$dom = str_get_html($html);

// ...or construct dom from file/url
$dom = file_get_html($path);

// strip h1 tags (and their content)
foreach ($dom->find('h1') as $node) {
    $node->outertext = '';
}
