preg_replace - matching all content between two tags

Question

I am working with a CMS system that is insisting on putting lots of junk markup & empty tags between </figure> and <figcaption>tags.

I'm trying to use a regular expression to match & remove this junk (sadly fixing the CMS isn't possible).

I seem to have created a regex that's a bit too hungry and is also stripping the tags.

$str = '<p></p><figure class="image"><img title="Screenshot 2014-08-26 16.34.12.png" alt="Screenshot 2014-08-26 16.34.12.png" src="/image/Screenshot%202014-08-26%2016.34.12.png" class="image-style-none" typeof="foaf:Image"></figure><p></p>
    <p>Â&nbsp;</p>
    <p></p><figcaption>Screenshot 2014-08-26 16.34.12.png</figcaption><p></p>
    <p>  </p>
    <p> </p>
    <p></p>';

preg_replace('#(</figure>).*?(<figcaption>)#s', '[replace-me]', $str);

Can anyone point me in the right direction?

Answer 1

preg_replace('#(?<=<\/figure>)(.*?)(?=<figcaption>)#ms', '[replace-me]', $str));

Aren't regular expressions just so fun!
