Sources of XML

XML can be obtained from a static file that is located on your Web server, or from a URL that refers to any site accessible to your Web server. The URL access is significant because it does not have to refer to a static file. It can refer to any page, including dynamic pages, that can return XML data. Database servers, for example, can respond to URLs by returning XML format data representing information stored in the database. The URL may contain parameters that select the data to be returned.
