But parsing raw html is error prone, and subject to change as the web designer reorganizes things. So many web servers also have a protocol intended for data (as opposed to intended for a browser). This is specific to each service, however. If you want to get started in your reading, you could google for "web services", which is one approach using SOAP & WSDL.
Note also that most servers have restrictions on the data you access this way. They may or may not be enforceable, but if you access a lot of data from a server, you may be too big a drain on its resources, if it's configured for browser access only.
