If I have a string like:
<p> </p> <p></p> <p class='a'><br /></p> <p class='b'> </p> <p>blah blah blah this is some real content</p> <p> </p> <p></p> <p class='a'><br /></p> How can I turn it into just:
<p>blah blah blah this is some real content</p> The regex needs to pick up s and spaces.
$result = preg_replace('#<p[^>]*>(\s| ?)*</p>#', '', $input);This doesn’t catch literal nbsp characters in the output, but that’s very rare to see.
Since you’re dealing with HTML, if this is user-input I might suggest using HTML Purifier, which will also deal with XSS vulnerabilities. The configuration setting you want there to remove empty p tags is %AutoFormat.RemoveEmpty.
