json parse in javascript

I have the following (snippet) variable:

var txt = {
        'start': {
                 'name':'Call start',
                 'data': {'next':'start/e3fe40'},
                 'id':'start',
                 'type':'standard---start'
        },
        'e3fe40': {
                'name':'Menu',
                'data':  {'next':'end/asd3rg'},
                'id':'e3fe40'
         }
};

I need to parse through the JSON and get info from the 'e3fe40' branch (without knowing how its going to be called.

Here's what I have:

var nxt = txt.start.data.next.substr(6,10); <-- works
console.log(nxt);                           <-- works
console.log(txt.start.data.next);           <-- works
console.log(txt.nxt.name);                  <-- nxt should contain 'e3fe40'

So, how do I go down a branch? txt.nxt.name won't work, txt.{nxt}.name won't work, etc....

Thanks, Dan

If You debug code by using debugging tool and put this code I think it will solve your problem 

alert(txt.e3fe40.name);

Assuming nxt = "e3fe40" you get the value by doing.

txt[nxt].name

Different ways of accessing the values,

txt.e3fe40.name txt['e3fe40'].name and one shown above.

txt.nxt.name is wrong. Because nxt is not a key in the Javascript object,

var key = txt.start.data.next.substr(6);
console.log(txt[key].name);
