Subject: Re: [PHP-DEV] unexpected behaviour in SimpleXML (php 5.2.2)

The attribute is not a child XML node. For walking through attributes
SimpleXML has $node->attributes() method.
And if($node->attributes()) check works as expected.
So I think $node->children() must be just for child XML nodes, not for
attributes (there is no sense to give back results for attributes since we
have attributes() method).
