Subject: Re: [PHP-DEV] SimpleXML bug
From: shane@caraveo.com (Shane Caraveo)

The problem is one of simplicity ;)
I ran into the same problem a couple days ago.  In the two examples, an 
array of element 'child' is expected.  That array may be one or more 
elements.  SimpleXML turns multiple children of the same element name 
into array's, but a single child is not.  I'm not sure what the right 
answere is for it though, other than conditionaly checking for a single 
child.

There's a part of me that thinks that children should be accessed via a 
function, but then you start getting dom-like:

$root->childNodes()[0]

and it always works.  It also prevents problems with something like:

<root child="test">
   <child>abcd</child>
</root>
