I'm trying to work with this XML feed that uses namespaces and i'm not able to get past the colon in the tags. Here's how the XML feed looks like:

<r25:events pubdate="2010-05-19T13:58:08-04:00">
<r25:event xl:href="event.xml?event_id=328" id="BRJDMzI4" crc="00000022" status="est">
 <r25:event_id>328</r25:event_id>
 <r25:event_name>Testing 09/2005-08/2006</r25:event_name>
 <r25:alien_uid/>
 <r25:event_priority>0</r25:event_priority>
 <r25:event_type_id xl:href="evtype.xml?type_id=105">105</r25:event_type_id>
 <r25:event_type_name>CABINET</r25:event_type_name>
 <r25:node_type>C</r25:node_type>
 <r25:node_type_name>cabinet</r25:node_type_name>
 <r25:state>1</r25:state>
 <r25:state_name>Tentative</r25:state_name>
 <r25:event_locator>2005-AAAAMQ</r25:event_locator>
 <r25:event_title/>
 <r25:favorite>F</r25:favorite>
 <r25:organization_id/>
 <r25:organization_name/>
 <r25:parent_id/>
 <r25:cabinet_id xl:href="event.xml?event_id=328">328</r25:cabinet_id>
 <r25:cabinet_name>cabinet 09/2005-08/2006</r25:cabinet_name>
 <r25:start_date>2005-09-01</r25:start_date>
 <r25:end_date>2006-08-31</r25:end_date>
 <r25:registration_url/>
 <r25:last_mod_dt>2008-02-27T14:22:43-05:00</r25:last_mod_dt>
 <r25:last_mod_user>abc00296004</r25:last_mod_user>
</r25:event>
</r25:events>

And here is what I'm using for code - I'll trying to throw these into a bunch of arrays where I can format the output however I want:

<?php

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://somedomain.com/blah.xml");
curl_setopt ($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml"));
curl_setopt($ch, CURLOPT_USERPWD, "username:password");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

$xml = new SimpleXmlElement($output);
foreach ($xml->events->event as $entry){
  $dc = $entry->children('http://www.collegenet.com/r25');
  echo $entry->event_name . "<br />";
  echo $entry->event_id . "<br /><br />";
}
