PHP Handling Namespace with SimpleXML

问题

I really need help with using namespaces. How do I get the following code to work properly?

<?php
$mytv = simplexml_load_string(
'<?xml version="1.0" encoding="utf-8"?>
 <mytv>
    <mytv:channelone>
        <mytv:description>comedy that makes you laugh</mytv:description>
    </mytv:channelone>
 </mytv>'
);

foreach ($mytv as $mytv1)
{
    echo 'description: ', $mytv1->children('mytv', true)->channelone->description;
}
?>

All I'm trying to do is get the content inside the name element.

when ever yu are using the namespaces in xml yu should define the namespaces what ever you use..! in the code what i posted you can see how you can define the namespace you are using..

you need to display the description specific to the namespace isn't it..? correct me if I'm wrong., and please post yur purpose properly so that i can understand your problem..

Use this code and see if you can get some idea..

$xml ='<mytv>
 <mytv:channelone xmlns:mytv="http://mycompany/namespaces/mytvs">
    <mytv:description >comedy that makes you laugh</mytv:description>
 </mytv:channelone>
</mytv>';

$xml = simplexml_load_string($xml);

$doc = new DOMDocument();  
$str = $xml->asXML(); 
$doc->loadXML($str); 

$bar_count = $doc->getElementsByTagName("description");

foreach ($bar_count as $node) 
{   
echo $node->nodeName." - ".$node->nodeValue."-".$node->prefix. "<br>";
}

here., the value, "$node->prefix" will be the namespace of the tag containing "description".

getElementsByTagName("description") is used to get all the elements in the xml containing description as tags...!! and then later using the "$node->prefix" you compare with the specific namespace as required for you and then print..
