Kevin, great article! This helped a lot. Question for you: how would I handle multiple namespace prefixes, such as the following:

[item:group]
[widget:typeA attr1="" attr2=""/]
[/item:group]

If I wanted to get the values of attribute one and two of the widget, how would that be done?

Thanks,

– MT

Great article. I have been trying to get a value from a node with a namespace for quite some time now and couldn’t quite figure it out.

Thanks.

SimpleXML and namespaces are sooo gay. This should be handled the same as non-namespaced attributes.

Kevin,
Thank you for this article. I bought the book previously and this missing topic is just what I’m stuck on. If you could indulge my ignorance, I am still stuck on how to parse multiple namespace items with multiple attributes on the same level. I am trying to parse the yahoo weather rss feed:

…

…

…

how do I get to sunrise for instance? $sunrise = ?
Thanks!

Anonymous,

Sure — just use the getNamespaces method: http://www.php.net/manual/en/function.simplexml-element-getNamespaces.php

Is there any way to (automatically) get the xmlns:dc URL from the code? I’d like to find the URI in code, but all examples have it hard-coded.

Is there any way to see what is contained in the buffer for $channel_itunes in the above example. I have tried the Zend debugger but is just states “Object of: SimpleXMLElement” and print_r gives me an empty SimpleXMLElement Object. If I could see the data that was contained in the buffer, I would be able to more accurately troubleshoot problems I was having without guessing as I am now.

Thanks.

I actually figured out the solution using your documentation and some experimentation.

foreach($rss->channel as $channel)
{
$channel_itunes = $channel->children(’http://www.itunes.com/dtds/podcast-1.0.dtd’);
$image_items = $channel_itunes->attributes();
$image = $image_items['href'];
}

joeblow,

Could you post your code sample again and escape your special characters (e.g. <)?

What about a line that has both a namespace and an attribute such as the following:

[broken code sample removed -Ed]

How would I grab the itunes:image reference in the preceding xml?
I’ve tried the following code snippet to no avail(and many others):

foreach($rss->channel as $channel)
{
$channel_itunes = $channel->children(’http://www.itunes.com/dtds/podcast-1.0.dtd’);
$image = $channel_itunes->image['url'];
}

Any help would be greatly appreciated.

[...] This article reveals the ‘special’ steps one has to take to read XML in PHP 5 containing namespaces—more psychological support with a bit more technical help. Another article, “XML Namespaces” does more of the same. [...]

Hmm okay. To get at the rdf:resource attribute in the rdf:li tag in the example above:


$feed = simplexml_load_file('http://www.sitepoint.com/recent.rdf');
$items = $feed->channel->items;
$items_rdf = $items->children('http://www.w3.org/1999/02/22-rdf-syntax-ns#');
$Seq_rdf = $items_rdf->Seq->children('http://www.w3.org/1999/02/22-rdf-syntax-ns#');
$lis = $Seq_rdf->li;
foreach ($lis as $li) { 
  $li_attr_rdf = $li->attributes('http://www.w3.org/1999/02/22-rdf-syntax-ns#');
  $resource = $li_attr_rdf['resource'];
  echo $resource . "\n";
}

Could we please have an example for the attributes please? I have failed to use the attributes method to get at a name spaced attribute contained in a name spaced element (and caused my scalp to bleed in the process!!!). In the end I regex’ed out the attribute to its own element so I could get SimpleXML to work; not so simple!
