[SOLVED] Parsing a String for URL

[codecrapht]

Hello, I have some code that pulls in an RSS feed. The issue is that the 'description' contains CDATA with text, link and images code. I just need to pull out 'parse' the image url and have it avalible in a string variable. I'm not sure what else to say, so please ask if you need more information. Thanks for your time and help!

Can I see an example description tag?  Also, you know how to actually get the data in description with like, SimpleXML, right?

Here is the item code:

 

<item>
  <title>Example URL</title> 
  <link>http://www.exampleurl.com/</link> 
  <guid isPermaLink="false">guid_2008-11-11-1876</guid> 
  <description>
    <![CDATA[ Some sample content is included here.<br><a border="0" href="http://www.exampleurl.com/" target="_blank"><img src="http://www.exampleurl.com/rss_image.jpg"/></a> ]]> 
  </description>
  <pubDate>Tue, 11 Nov 2008 00:00:00 -0800</pubDate> 
</item>

 

I’m not familiar with SimpleXML. Will that break out the CDATA? Thank you very much for your help!

A good place to read up on it.

By “get the data in description with like, SimpleXML” do you mean just showing the text, link and image? Is so then yes, I have the description showing, but I need to just show the image. I have my own descriptions. Thanks again!

Let's say you have this string:

 

    <![CDATA[ Some sample content is included here.<br><a border="0" href="http://www.exampleurl.com/" target="_blank"><img src="http://www.exampleurl.com/rss_image.jpg"/></a> ]]>

 

If you have that string you can easily get the img url by doing the following:

 

<?php
$string = ' <![CDATA[ Some sample content is included here.<br><a border="0" href="http://www.exampleurl.com/" target="_blank"><img src="http://www.exampleurl.com/rss_image.jpg"/></a> ]]>';

$parsed = explode("src=\"", $string);
$parsed = explode("\"/>", $parsed[1]);
$imageUrl = $parsed[0];
echo $imageUrl;
?>

Great, thanks!
