How to get the innerHTML in firefox

[EruditePig]

First, i am a Noob.
I wanna to get the content of the opened entry in Google Reader. I used the below command to get the div section.
document.getElementById('current-entry').getElementsByClassName('item-body')
and the below snapshot was the div section in firebug.

However, I cannot get the content by innerHTML or outerHTML or textContent.

if i use
var ib = document.getElementById('current-entry').getElementsByClassName('item-body') ;
var tc = ib.getElementsByTagName('p')
the firebug return the error ib.getElementsByTagName is not a function.

Can you help me?

getElementsByClassName('') (which by the way is not supported in all browsers) will return a collection, as will getElementsByTagName(''), so what you are looking for is probably something like this:

var ib = document.getElementById('current-entry').getElementsByClassName('item-body')[0]
var tc = ib.getElementsByTagName('p')[0]
alert(tc.innerHTML)

but those [0]'s depend on how your page is structured
