Matching the first <p> that does not start with an image in regexp
原标题:

In PHP, I m trying to match the first paragraph tag that is not immediately followed by an <img> tag, and add a class to that paragraph tag.

For example, it would add a class to:

<p>Text</p>

and

<p><strong>Strong text</strong></p>

but not:

<p><img src="" /></p>

Here s what I have so far which successfully adds a class to the first paragraph tag, but it doesn t skip until it finds a paragraph tag that doesn t immediately contain an image:

preg_replace( /<p>/ , <p class="first"> , $text, 1);

Thoughts? Apologies if that doesn t make sense.
