Hi, I'm in Australia and was wondering if anyone can suggest me as to how I can access data from the server which some web page is using to provide information. To be specific, I want to write an app for a cityrail in australia but couldn't figureout as to where to start. Thanks

PS.: also the busybox wget applet should do it if you like it more compact.

@farmatito: thanks for the reply, I'll be looking through them. However, I had the impression that provider of such services via internet have a particular API to interact with their data server, don't they? like facebook etc.. thanks

In many cases you are forced to download the HTML, parse it (in one of several ways), extract the information you're looking for and use that. This is sometimes called "site scraping".
To supply information, via forms, you need to create the specific GET or POST request and simulate entering data into a form and clicking the "Send" button.

Have a go with libcurl, it's pretty basic but has some special features:
http://curl.haxx.se/libcurl/c/example.html
You'll find an example with HTML parsing too, using libxml.

jaeezzy:
in C:
to fetch data from a HTTP server, use libcurl.
To use XML-RPC, use libsoup (<http://library.gnome.org/devel/libsoup/stable/libsoup-24-XMLRPC-Support.html>).
To automate HTML forms, use libsoup (<http://library.gnome.org/devel/libsoup/stable/libsoup-2.4-HTML-Form-Support.html>).
or if you use Python:
just use urllib, BeautifulSoup and xmlrpclib (<http://www.crummy.com/software/BeautifulSoup/>) (simpler to use than the above).
