XML read using php

Question

How to read the below xml using php?

<?xml version="1.0" encoding="UTF-8"?>

<video>

<youtube> youtube video url </youtube>

</video>

I tried the code below but seems not working:

$dom = new DOMDocument();

$dom->load('new_result.xml');

$results = $dom->documentElement;

foreach( $results  as $result)

{

foreach( $result->getElementsByTagName('youtube') as $youtube )

{

echo ' video url ' . $youtube->nodeValue;

}

}

No need for anything fancy, just use ->getElementsByTagName() method after you've loaded it up:

$dom->load('new_result.xml'); // load the file
// use ->getElementsByTagName() right away
$youtube = $dom->getElementsByTagName('youtube');
if($youtube->length > 0) { // if there are youtube nodes indeed
    foreach($youtube as $y) { // for each youtube node
        echo $y->nodeValue;
    }
}
