Hi
In order to build a weather prediction page, I was thinking to write
down a Javascript (on the client). This javascript should contact a
server (www.live.com) in ordert to extract the weather forecast.
In summary, I want a javascript based on the html client (internet
Explorer), creating a connection and extractign the data.
This sounds simple but for whatever reason, I cannot manage to extract
any data of this XML page.
Perhaps can you help me?
This code you can past it, as a document by it s own and test it and
complete it for your own pages (the server is ready to answer you).
thanks
