Remove all text within specific tags

Question

I am interesting in removing all the text within the following tags:

<p class="wp-caption-text">Remove this text</p>

Can anybody give me an idea of how this can be done in php?

Thank you very much

Answer 1

Get rid of the tag and content inside of it:

 $content = preg_replace('/<p\sclass=\"wp\-caption\-text\">[^<]+<\/p>/i', '', $content);

or if you want to preserve the tags:

 $content = preg_replace('/(<p\sclass=\"wp\-caption\-text\">)[^<]+(<\/p>)/i', '$1$2', $content);
