Parsing XML namespaces?

Question

Using JavaScript/Ajax?

I'm trying to extract values from:

<yweather:astronomy sunrise="6:34 am"   sunset="8:38 pm"/>

Looking for something like:

var response = transport.responseXML.getElementsByTagName("channel");
sunrise = response[0].getElementsByTagName("yweather:astronomy").item(0).Attributes["sunrise"].Value;

But nothing works so far. :'( Thanks.

There is a special version of getElementsByTagName for namespaces: getElementsByTagNameNS.

For example:

var response = transport.responseXML.getElementsByTagName("channel");
var sunrise = response[0].getElementsByTagNameNS("[Namespace URI]", "astronomy")[0].getAttribute("sunrise");

...where [Namespace URI] is the URI of the yweather namespace.
