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).

ok no children

ok has one child: <newnode>
But the same will happen if the subnode has an attribute like:
> $str = '<rootnode><subnode id="2"></subnode></rootnode>';
I think is correct, in fact (if I'm right) an attribute is a child.
Following DOM the tree is:
rootnode
|
subnode
|
id
Here an example explaining that

Please someone else to confirm.
See you
