Description:
------------
Having a XML string, where one or more of the nodenames contains a - 
(dash) it is impossible to return that value, as dash is not allowed in 
attributes on an object. Consider replacing all dash'es with 
underscores.

Reproduce code:
---------------
<?php
	$xml_string = "<response><http-code>200</http-code></response>";
	$xml = new SimpleXMLElement($xml_string);
	
	print_r($xml);
?>

Expected result:
----------------
SimpleXMLElement Object ( [http-code] => 200 )

Actual result:
--------------
SimpleXMLElement Object ( [http_code] => 200 )

Oops, but accident i switched the "Expected result" and "Actual result"

Expected result should be SimpleXMLElement Object ( [http_code] => 200 )
Actual result should be SimpleXMLElement Object ( [http-code] => 200 )

Sorry for the inconvinience.

This works fine, so long as you use the right syntax. Example 3 at 
http://au2.php.net/manual/en/simplexml.examples-basic.php covers this.

In your case, you would access http-code as follows:

$httpCode = $xml->{'http-code'};
