Subject: help me make this prettier and more ruby-ish

Hi,

I know this can be done much cleaner and with prettier code...but I
was having trouble getting my head around doing it with collect.

"infobar_link" creates hyperlinks - it takes a 1st parameter of a
string denoting a lookup value, and an optional second string
parameter for the link text.

So "infobar_sites" is a list of sites I want to create links to, and
as you can see they can either be just a lookup value (single string),
or an array with the lookup and a title to override the default.  Then
I just enumerate thru and create a list of the links.


infobar_sites = [ 	["usmarket", "The Market"],
					"internet",
					["etf", "ETFs"],
					"china",
					"energy",
					["ce", "Electronics"],
					"media",
					"gold",
					"telecom",
					"biotech",
					"retail",
					"japan",
					"india" ]
output = ""
infobar_sites.each do |args|
	link = nil
	if args.is_a? String
		link = infobar_link(args)
	else
		link = infobar_link(args[0], args[1])
	end
	output += "<li>#{ link }</li>"
end
output

any help greatly appreciated...

thanks
- Rob
