I recommend using a real namespace-aware XML parser if at all possible, especially when dealing with external services. There is no guarantee that the namespace prefix will remain constant over time, for example.

Most JavaScript DOM parsers will include getElementsByTagNameNS(), which will let you find elements with the actual namespace.

The process might look something like this, assuming your data was in xml_file.

var namespace = 'http://aws.example.com/';
var parser = new DOMParser(); // Webkit, IE has its own
var xml = parser.parseFromString(xml_file, "text/xml");    
var year = xml.getElementsByTagNameNS(namespace, 'year')[0]; // returns the first aws:year element
var year_value = year.getAttribute('number');

You can parse the DOM when you use double backslash to escape the colon

ex.

$("aws\\:year").attr('number')

edit:

the solution above does not work with webkit browsers. better solution 

$("[nodeName=aws:year]").attr('number')

didn't check this out though.
