How do you access an XML node with a colon (:) in it? - php

Question

I am trying to access a Taleo RSS/XML feed and parse the data. I am using SimpleXML, and it is loading in all of the regular data correctly, such as <title>, <link>, etc.
However, there are several nodes that are formatted like <taleo:reqId> or <taleo:location>, and I can't seem to figure out how to access that data. It's not being returned by SimpleXML.
`$xml = simplexml_load_file('https://chp.tbe.taleo.net/chp03/ats/servlet/Rss?org=DRAGADOS&cws=1&WebPage=SRCHR&WebVersion=0&_rss_version=2');`
Returns in web browser source:
`<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="https://chp.tbe.taleo.net/chp03/ats/rss/taleorssfeed.xsl" ?>
<?xml-stylesheet type="text/css" href="https://chp.tbe.taleo.net/chp03/ats/rss/taleorssfeed.css" ?>
<rss xmlns:taleo="urn:TBERss" version="2.0">

I find it easier sometimes to split out the data for different namespaces in this case. So when going through the <item> data, you can extract all the elements for a specific namespace (the 'taleo' elements in this case) using ->children('namespaceURN') and it then access the data in a similar way to all the other times but using this new set of nodes as the basis.
foreach ( $xml->channel as $channel ) {
echo "title=".$channel->title.PHP_EOL;
foreach ( $channel->item as $item ) {
echo "pubDate=".$item->pubDate.PHP_EOL;
// Extract the elements for taleo namespace
$taleo = $item->children("urn:TBERss");
echo "taleo:reqId=".$taleo->reqId.PHP_EOL;
}
}
