[SOLVED] namespace prefix lookup

[saipkjai]

hi

 

  Right now, I'm trying to retrieve the prefix of the name space using the lookupprefix(String url). But somehow, it does not return me anything. Am I miss use the function?

 

the approach that I'm using is

 

$xml = simplexml_load_file($file);

 

then for each of the content , I do

 

		$prefix = $entry->content->lookupPrefix('http://www.w3.org/1999/xhtml');
		echo "<p>$prefix</p>";

 

XML sample

 

  <content type="xhtml" xmlns:xhtml="http://www.w3.org/1999/xhtml">

 

    <xhtml:div>This is also <xhtml:em>very</xhtml:em> exciting. &</xhtml:div>

  </content>

 

Am I missing something?

 

thx for the help

you will need to declare your namespaces to get to the content you desire. i did it like this:

 

$namespaces = $feed->getNamespaces(true);
$content = $feed->channel->item->children($namespaces['content']);

 

The XML:

<?xml version="1.0" ?>
           		<rss version="2.0"
				xmlns:dc="http://purl.org/dc/elements/1.1/"
			    xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"
				xmlns:admin="http://webns.net/mvcb/"
				xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
				xmlns:content="http://purl.org/rss/1.0/modules/content/">

hm.. I dont kinda understand what you mean....

 

let say I have a feed like this

 

<feed xmlns="http://www.w3.org/2005/Atom"> …

  <content type="xhtml" xmlns:x="http://www.w3.org/1999/xhtml">

     <x:div><x:strong>very</x:strong> good</x:div>

   </content> … </feed>

 

am I suppose to use the lookupprefix('http://www.w3.org/1999/xhtml') to retrieve x within the xmlns:x ?

 

thx

if you would post your code, it would probably help out other people in the future
