Description:
------------
If you try to open remote XML file and the file does not exist it return true instead of false.

Also in any error script create a warning which IMHO is "stupid" thing to do. For example: We use Zend Platform and have enabled warning events. And everytime xml file can't be read because of net failure, we have a new warning. But if file can't be open it must return false and then in some other mechanism to report what kind of an error.

I talk with Christian and disapoint me that Exceptions is not on todo list. Instead of that there is some other "better" error handling. I think Exceptions would be great in such situations. Java do it, .net also. Why should be any difference here.

Reproduce code:
---------------
$reader = new XMLReader();
$res = $reader->open('http://somesite.com/filename.xml');

if ($res) {
    echo "ok";
} else {
    echo "not found";
}

?>

Expected result:
----------------
not found

Actual result:
--------------
ok
