使用Reg Expression重新格式化RSS提要中的图像

Question

I am creating some RSS feeds using PHP (5.2) from a MySQL db specifically for an iPhone app I am making through AppMakr.

They are taken from articles on a website which contain images embedded in them, however in the feeds they don't look great. What I want to try and do is whenever there is an image surround it in <p> so they are on their own line and don't try to wrap around article text.

The format of a image is like this:

 <a rel="lightbox" href="http://images.domain.comk/543/image1.jpg"><img class="imageright" src="http://images.domain.comk/543/image1.jpg" alt="" width="300" height="250" /></a>

So basically surrounded with a <a href> and with a class of "imageright" or "imageleft".

What I would love to change this to is:

 <p><img src="http://images.domain.comk/543/image1.jpg" alt="" width="300" height="250" /></p>

Basically removing the href and imagexxxx class and surrounding in p tags.

I am thinking preg_replace will prob have to be used, but at a loss to what I would actually use for it. Any help is very appreciated.

Answer 1

So you will need to use a regexp for matching like this one:

<a(.*)><img(.*)class="imageright" (.*)></a>

And then a replace regexp like this:

<p><img$2$3></p>

This is not the most flexible one but it should do the trick for preg_replace()
