Sectors and there Symbols: WHERE ?

Hi,

The AMEX has sector symbols Like
XBD - brokerage
XNG - Nat Gas
DFX - Defense

Other indices like SP500, INDU, NAS, etc

Q: Where can I find a one stop shop that tells me what stock symbols make up these sectors and common indices ???

[Are they in the wall street journal ???, ....I am really after a website that maintains the list so I can down load the symbols and update my database when and if things change.]

 

I use TeleChart (http://www.telechart.com/). It's not free, but it is reasonably priced and pretty clean.

Yes, but how can I download a List, this site is not in a easy XML or HTML or csv download form ?

Thanks that helps, heaps
