Someone help me i'm loosing my mind (Simple XML not so simple)

[Kritical_V]

Hello,

 

I have been working on a small piece of code for the last day or so, and I have gone through over one hundred resources, and frankly it's beaten me.

 

What I am attempting to do is pull a small bit of data from a XML file served through the youtube api.

 

I have am attempting to pull data from a xml file through a url like the below:

https://gdata.youtube.com/feeds/api/playlists/CA22CCE64DD2CCBE?v=2&max-results=1

 

The code should pull data about latest video from a selected playlist on youtube...

 

 
<?php
    // FEED URL
    $feedURL = 'https://gdata.youtube.com/feeds/api/playlists/CA22CCE64DD2CCBE?v=2&max-results=1';
    
    // read feed into SimpleXML object
    $sxml = simplexml_load_file($feedURL);?>

//Code to output a specific piece of data from the xml file
<?php echo $sxml->entry->{'media:group'}{'media:description'}; ?>

 

I have skimmed the fat off the xml file so you can see the piece of data easily that I am trying to output.

 

<?xml version='1.0' encoding='UTF-8'?>
<feed xmlns='http://www.w3.org/2005/Atom' xmlns:media='http://search.yahoo.com/mrss/' xmlns:openSearch='http://a9.com/-/spec/opensearch/1.1/' xmlns:gd='http://schemas.google.com/g/2005' xmlns:yt='http://gdata.youtube.com/schemas/2007' gd:etag='W/"CUAFSH47eCp7I2A9WhJQEE4."'>

<entry gd:etag='W/"YDwqeyM."'>
<media:group>
<media:player url='https://www.youtube.com/watch?v=dCVmk66ldkE9w&feature=youtube_gdata_player'/></media:group>
</entry>
</feed>

 

I need my code above to pull the media:player url and echo it out in plain text form.

 

It's seems like I don't no my syntax for working with xml and I guess it's something simple.

 

If anyone can help I would be greatly appreciated.

here you go, 

 

$xml = "<?xml version='1.0' encoding='UTF-8'?>
<feed xmlns='http://www.w3.org/2005/Atom' xmlns:media='http://search.yahoo.com/mrss/' xmlns:openSearch='http://a9.com/-/spec/opensearch/1.1/' xmlns:gd='http://schemas.google.com/g/2005' xmlns:yt='http://gdata.youtube.com/schemas/2007' gd:etag='W/"CUAFSH47eCp7I2A9WhJQEE4."'>
<entry gd:etag='W/"YDwqeyM."'>
<media:group>
<media:player url='https://www.youtube.com/watch?v=dCVmk66ldkE9w&feature=youtube_gdata_player'/></media:group>
</entry>
</feed>";

$sxml = simplexml_load_string($xml);
foreach ($sxml->entry as $entry) {
// get video player URL
$media = $entry->children('http://search.yahoo.com/mrss/');
$attrs = $media->group->player->attributes();
$watch = $attrs['url'];
print $watch;
}

 

i loaded it from a string, but the principle is exactly the same. hope it helps. this returns : https://www.youtube.com/watch?v=dCVmk66ldkE9w&feature=youtube_gdata_player

SimpleXML is actually very simple if you know how to utilize the library.

 

To echo out the url attribute of the media:player node, use the following code:

 

$feedURL = 'https://gdata.youtube.com/feeds/api/playlists/CA22CCE64DD2CCBE?v=2&max-results=1';
    
// read feed into SimpleXML object
$sxml = simplexml_load_file($feedURL);
$url = (string)$sxml->entry->children('media', true)->group->player->attributes()->url;

echo $url;
