Using the following js code

var channel = xml.documentElement.getElementsByTagName("channel");
var c = channel.item(0).getElementsByTagName("ttl").item(0).text;

I get 60 value for var c. How can i get the "humidity="86" attribute from yweather:atmosphere tag

Duplicate question. See stackoverflow.com/questions/1083565/parsing-xml-namespaces for the answer. — Cheeso

This should do it for you:

var atmoNode = document.getElementByTagname("yweather:atmosphere").item(0);
var humidity_string = atmoNode.attributes.humidity.value;

You want to access humidity via the attributes property.
