Question

I’m working in WordPress and need to be able to remove images and empty paragraphs. So far, I’ve found out how to remove images without a problem. But, I then need to remove empty paragraph tags. I’m using PHP preg_replace to handle the regex functions.

So, as an example, I have the string:

<p style="text-align:center;"><img src="http://www.blah.com/image.jpg" alt="Blah Image" /></p><p>Some text</p>

I run this regex on it:

/<img.*?(>)/

And I end up with this string:

<p style="text-align:center;"></p><p>Some text</p>

I then need to be able to remove the empty paragraph. I tried this, but it removes all paragraphs and the contents of the paragraphs:

/<p[^>]*><\/p[^>]*>/

Any help/suggestions is greatly appreciated!

Answer 1

The correct regex is no regex. Use an HTML/DOM Parser instead. They’re simple to use. Regex is for regular languages (which HTML is not).
