SimpleXML and mixed, nested namespaces

I work with several third party marketplace APIs, one of which is Amazon's MWS API.
When processing their GetMatchingProductForId response I discovered that they sometimes namespace the XML nodes (with ns2).

PHP's SimpleXML doesn't allow access to namespaced nodes via the usual interface of $simpleXml->node but I found you can specify a namespace to the children() method like so:

$simpleXml
    ->children('ns2', true)
    ->namespacedNode

That works great but then I hit a problem. As I mentioned, Amazon namespace some of the nodes but not all and the node I was really after was not namespaced itself but was a child of a namespaced node. After I applied the code above I found that I couldn't access the child node:

$simpleXml
    ->children('ns2', true)
    ->namespacedNode
    ->nonNamespacedNode

I thought all was lost until I discovered you can reset SimpleXML's namespace filter back to none again with another call to children() so you can get at the non-namespaced child node:

$simpleXml
    ->children('ns2', true)
    ->namespacedNode
    ->children()
    ->nonNamespacedNode

Jasmine and Jasq

Recently I've started using Jasmine - a BDD framework - to test some pretty complex JavaScript I've been writing for work. We're using RequireJS for our JavaScript and we found a great plugin for Jasmine to make it play nicely with AMD modules called Jasq.

All works beautifully except for one thing: the Jasq docs say to wrap your specifications in a require block but that didn't seem to work for me. Once I changed them to define blocks (see below) everything started working. I don't know why this is and it doesn't seem anyone else had the same issue so perhaps I've done something wrong but I just thought I'd put this out there in case anyone else runs into the same issue.

define(['jasq'], function ()
{
  describe('My Tests', 'thing/to/test', function()
  {
    it('should do something', function(thingToTest)
    {
        //...
    });
  });
});
