Strip Tags and everything in between

How can i strip <h1>including this content</h1>

I know you can use strip tags to remove the tags, but i want everything in between gone as well.

Any help would be appreciated.

You could use an XSLT stylesheet and match all tags to themselves except for the h1 tag which would be matched to the empty string, and then apply it to your document. Might be a bit too heavy-weight for doing something as simple as this though.

You also use strip_tags to remove the tags and also everything in between..

$html contain your html or php from where you want to remove the tags.

strip_tags($html,"");

Try this i think this will work for you.

As you’re dealing with HTML, you should use an HTML parser to process it correctly. You can use PHP’s DOMDocument and query the elements with DOMXPath, e.g.:

$doc = new DOMDocument();
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
foreach ($xpath->query('//h1') as $node) {
    $node->parentNode->removeChild($node);
}
$html = $doc->saveHTML();

If you want to strip ALL tags and including content:

$yourString = 'Hello <div>Planet</div> Earth. This is some <span class="foo">sample</span> content!';
$regex = '/<[^>]*>[^<]*<[^>]*>/';
echo preg_replace($regex, '', $yourString);
#=> Hello  Earth. This is some  content!

HTML attributes can contain < or >. So, if your HTML gets too messy this method will not work and you'll need a DOM parser.

Try this:

preg_replace('/<h1[^>]*>([\s\S]*?)<\/h1[^>]*>/', '', '<h1>including this content</h1>');

Example:

echo preg_replace('/<h1[^>]*>([\s\S]*?)<\/h1[^>]*>/', '', 'Hello<h1>including this content</h1> There !!');

Output:

Hello There
