Parsing XML+ATOM feeds

[weee]

Hello everyone,

 

I am having problem trying to fetch data from certain feeds.  The problem is, the feeds aren't just using XML or just atom, it is a combo of both.

 

Here is an example of YouTube's feed:

<?xml version='1.0' encoding='UTF-8'?><entry xmlns='http://www.w3.org/2005/Atom' xmlns:media='http://search.yahoo.com/mrss/' xmlns:gd='http://schemas.google.com/g/2005' xmlns:yt='http://gdata.youtube.com/schemas/2007'><id>http://gdata.youtube.com/feeds/api/videos/qzUuAIPPrGQ</id><published>2010-11-02T15:10:24.000Z</published><updated>2010-11-04T22:09:22.000Z</updated><category scheme='http://schemas.google.com/g/2005#kind' term='http://gdata.youtube.com/schemas/2007#video'/><category scheme='http://gdata.youtube.com/schemas/2007/categories.cat' term='Film' label='Film & Animation'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='mysteryguitarman'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='mystery'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='guitar'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='man'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='mgm'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='joe'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='penna'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='jp'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='balinese'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='bali'/><category scheme='http://gdata.youtube.com/schemas/2007/keywords.cat' term='instruments'/><title type='text'>Bali Instruments</title><content type='text'>Behind the Scenes: http://bit.ly/BehindTheScenesBali

What do you recommend doing to getting data out of feeds such as this?

 

Thank you,

Atom is just a way of coding XML (or something like that) just like RSS. You can use just use SimpleXML http://php.net/manual/en/book.simplexml.php

I have been trying to understand this for quite awhile now and I cannot seem to get the atom values extracted from the feed.  Could you please show me an example?

 

Thank you!
