Hi,
I'm not an expert, but in your example

--------
> $str = '<rootnode><subnode></subnode></rootnode>';
> $x = new SimpleXMLElement($str);
>
> if($x->subnode->children())
>     print 'yes';
>     else
>         print 'no';
> ---------
> will print 'no';


ok no children

If the
> $str='<rootnode><subnode><newnode></newnode></subnode></rootnode>';
> it will print yes.


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
