I get the same file as you if I dont append the "?WSDL" onto the end of the URL.

Can you confirm you definitely did this as the file you attached looks like the output of the webservice test page.

The URL should be exactly as follows: "http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL".

You can visit either through your browser

http://wsf.cdyne.com/WeatherWS/Weather.asmx

then

http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

and you should see a difference, the first is the webservice test page the second should be the WSDL definition which looks like a XML file.

If you are not getting a difference I'm not sure what is going wrong.
