PHP Simple_XML with namespaces

Had to read in an external RSS file from T3 and needed to drill into the "content" node which had a namespace. Using traditional ways of echoing out this node was not working so searching the net found a nice simple solution.

Below is the code to loop thru the "items" node without the name namespace involved:

<?php
$url = "http://best-apps.t3.com/category/platforms/android/feed/";

//download the feed from t3 with fopen
$handle = fopen($url, "r");
while (!feof($handle)) {
	$contents .= fread($handle, 8192);
}
fclose($handle);
//echo $contents;

$xml = simplexml_load_string($contents);
//print_r($xml);

echo "
    "; $i = 0; foreach($xml->channel->item as $item) { $alt_bg = (fmod($i, 2)) ? "bg-alt-even" : "bg-alt-odd"; //alternative background colour thing ?>
  • <?php echo $item->title?>
  • <?php $i++; } echo "
"; ?>

 

Below code includes the way I drilled into the namespace for "content:encoded"

<?php
$url = "http://best-apps.t3.com/category/platforms/android/feed/";

//download the feed from t3 with fopen
$handle = fopen($url, "r");
while (!feof($handle)) {
	$contents .= fread($handle, 8192);
}
fclose($handle);
//echo $contents;

$xml = simplexml_load_string($contents);
//print_r($xml);

echo "
    "; $i = 0; foreach($xml->channel->item as $item) { $alt_bg = (fmod($i, 2)) ? "bg-alt-even" : "bg-alt-odd"; //alternative background colour thing //Use that namespace from "content" $namespaces = $item->getNameSpaces(true); $content = $item->children($namespaces['content']); echo $content->encoded; ?>
  • <?php echo $item->title?>
  • <?php $i++; } echo "
"; ?>

The code reference is just a mock up and will need cleaning up but gives you an idea at least.
