You're right, that's a typo :)
You are also right about attributes not having attributes. But in this
case value returned by xpath() should be either array of values or false
or sth else, because if you are getting a SimpleXMLElement in which you
have [EMAIL PROTECTED] which contain what you were looking for and not being
able to access them via attributes() method is somewhat wrong IMO.

I think there are two errors in this reproduce code. First, there's a
typo in the innermost foreach, $atribute instead of $attribute.
Secondly, that XPath expression selects attributes (which explains why
attributes() returns NULL, as attributes cannot have attributes),
whereas it should select nodes. This code works as expected:
Reproduce code:
---------------
$xml = simplexml_load_file('./test.xml');
foreach ($xml->xpath('//[EMAIL PROTECTED]') as $node)
{
foreach($node->attributes() as $attribute => $value)
echo $attribute . " = " . (string)$value . "\n";
}

Description:
------------
When looking for list of values of a certain attribute in xml via
xpath() method, the returned SimpleXMLElement object's attributes()
method does not properly return array of attributes.
Reproduce code:
---------------
test.xml:
<?xml version="1.0"?>
<test>
<sth attr="1" />
<sth attr="2" />
<sth attr="3" />
</test>
index.php:
<pre>
<?php
$xml = simplexml_load_file('./test.xml');
$result = $xml->xpath('//@attr');
foreach($result as $node)
{
var_dump($node);
foreach($node->attributes() as $attribute => $value)
echo $atribute . " = " . (string)$value . "\n";
echo "---\n";
}
?>
</pre>
Expected result:
----------------
object(SimpleXMLElement)#2 (1) {
["@attributes"]=>
array(1) {
["attr"]=>
string(1) "1"
}
}
attr = 1
---
object(SimpleXMLElement)#3 (1) {
["@attributes"]=>
array(1) {
["attr"]=>
string(1) "2"
}
}
attr = 2
---
object(SimpleXMLElement)#4 (1) {
["@attributes"]=>
array(1) {
["attr"]=>
string(1) "3"
}
}
attr = 3
---
Actual result:
--------------
object(SimpleXMLElement)#2 (1) {
["@attributes"]=>
array(1) {
["attr"]=>
string(1) "1"
}
}
---
object(SimpleXMLElement)#3 (1) {
["@attributes"]=>
array(1) {
["attr"]=>
string(1) "2"
}
}
---
object(SimpleXMLElement)#4 (1) {
["@attributes"]=>
array(1) {
["attr"]=>
string(1) "3"
}
}
