PHP function that removes unclosed html tags

[Mudsaf]

Hello, i'm wondering how to remove all unclosed tags like below

<a href='<mysite'>Yeooeoeoo //Remove this<ul><li>Oh no this has links too..</li> //Keep working tags</ul>

I'm not sure does strip_tags(); remove them.

strip_tags();

strip_tags may display strange behavior with invalid markup, it might remove too much. Finding invalid HTML like that isn't a trivial task because there are a ton of possible edge cases, but I'm sure there's a regular expression that can do most of it.
