Applescript reading CNN news updates on twitter

Is it possible for twitter to read the latest tweet of CNN breaking news and speak it aloud?

Thanks,
Elijah

Model: MacBookPro
AppleScript: 2.3
Browser: Firefox 3.6
Operating System: Mac OS X (10.6)

set username to "cnn"
say getlasttweet(username)
on getlasttweet(username)
	set myURL to "http://twitter.com/" & username
	set content to do shell script "curl " & myURL
	if content is not "<html><body>You are being <a href=\"http://twitter.com/suspended\">redirected</a>.</body></html>" and content does not contain "<h2>Sorry, that page doesn't exist!</h2>" and username is not "login" and username is not "home" then
		if content contains "<a class=\"entry-date\" rel=\"bookmark\" href=\"" then
			set text item delimiters to "<a class=\"entry-date\" rel=\"bookmark\" href=\""
			set content to text item 2 of content
			set text item delimiters to "\">"
			set content to text item 1 of content
			set lasttweet to do shell script "curl " & content & " | textutil -stdin -stdout -format html -convert txt -encoding UTF-8 "
			set text item delimiters to "Login Join Twitter!\r\r"
			set lasttweet to text item 2 of lasttweet
			set text item delimiters to "\r"
			set lasttweet to text item 1 of lasttweet
		else
			return ""
		end if
	else
		display dialog "This username does not exist or is not available."
	end if
end getlasttweet

How do I get rid of it saying these:
RT @cnnbrk: and http://on.cnn.com/dnn7hf

This happens at the beginning and at the end of the post.

…text item delimiters?

Sorry…I’m such a newb to applescrips…any way you can post a quick sample code?

BTW…thank you soooo much! I wouldn’t of been able to do ANYTHING with applescripts without you! (-:

set thetext to "Wee.:'/Whoa"
set AppleScript's text item delimiters to ".:'/"
set thelist to text items of thetext
(*set theitem to text item 2 of thetext*)
