Hi,
I'm trying to write a regular expression that will strip all tag attributes except for the SRC attribute. For example:
<p id="paragraph" class="green">This is a paragraph with an image <img src="/path/to/image.jpg" width="50" height="75"/></p>
Would be returned as:
<p>This is a paragraph with an image <img src="/path/to/image.jpg" /></p>
I have a regular expression to strip all attributes, but I'm trying to tweak it to leave in src. Here's what I have so far:
<?php preg_replace('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i', '<$1>', '<html><goes><here>');
Using PHP's preg_replace() for this.
Thanks! Ian
