Simple Dome to get url NOT inside an <a href tag

[bschultz]

I posted this....http://forums.phpfreaks.com/topic/297984-multiple-regex-on-the-same-string/

 

If you don't want to read the original post, I'm trying to abandon Wordpress, but still use the functionality of a couple of plugins. 

 

Not seeing any responses tells me that maybe I should be barking up a different tree.  Is it possible to parse a database post and look for a URL that is NOT inside an a href tag?

 

I Googling, I didn't see anything in the simpledom examples about scraping for anything OUTSIDE of a tag.

 

Thanks!

I don't understand what you are asking. What's a database post that can be parsed?

[bschultz]

I used Wordpress.  I want to bail on Wordpress.  I've moved the Wordpress posts to a new database.  I'm displaying the post on the page.  Using Wordpress, I could have a post that read:

 

This is a post.  Here is an mp3 address.  (with the address shown, no a href tages needed)

 

The Wordpress plugin would the the url and display an html5 audio player on the site for that mp3.  Another plugin would take a Youtube link and embed the movie in a player.

 

I want to scrape, or parse, the database content...pull out the mp3 url's...and replace them with an html5 player.

Something like this.

<?php
$string = <<<DATA
<div itemprop="commentText" class='post entry-content '>

<p> I'll post some mp3 links in this string like http://www.stephaniequinn.com/Music/Allegro%20from%20Duet%20in%20C%20Major.mp3	and also try it without the protocol </p> www.stephaniequinn.com/Music/Allegro%20from%20Duet%20in%20C%20Major.mp3 just for good measure.<br />http://www.stephaniequinn.com/Music/Mozart%20-%20Presto.mp3           stephaniequinn.com/Music/Mozart%20-%20Presto.mp3 is not looking for any url patterns.<br />
