Hello,

How do I extract the URL from here with MagicParser?

Hi There, That XML segment

Hi There,

That XML segment looks like it is part of an RSS format feed, and so you would use it with Magic Parser using the format string "xml|RSS/CHANNEL/ITEM/".

To access the URL of the Podcast (which I assume is the URL attribute of the enclosure item); you would use the following code in your myRecordHandler function:

$url = $item["ENCLOSURE-URL"];

I've saved your XML above into a test file called podcast.xml, and written an example script to show how you would extract the URL:

Podcast Example

Here's the source code to that script:

<?php
  require("MagicParser.php");
  function myRecordHandler($item)
  {
    print $item["ENCLOSURE-URL"];
  }
  MagicParser_parse("podcast.xml","myRecordHandler","xml|RSS/CHANNEL/ITEM/");
?>

If the Podcast feed is not part of an RSS document, then you would do exactly as above except that you would use the Format String "xml|ITEM/".

Cheers!
David.
