There are many benefits to using XML on the Web; let us take a look at the major ones -

• It delivers data for local computation. Data delivered to the desktop is available for local computation. The data can be read by the XML parser, then delivered to a local application such as a browser for further viewing or processing. Or the data can be manipulated through script or other programming languages using the XML Object Model.
• It gives users an appropriate view of structured data. Data delivered to the desktop can be presented in multiple ways. A local data set can be presented in the view that is right for the user, dynamically, based on factors such as user preference and configuration.
• It enables the integration of structured data from multiple sources. Typically, agents will be used to integrate data from back-end databases and other applications on a middle-tier server, making this data available for delivery to the desktop or to other servers for further aggregation, processing, and distribution.
• It describes data from a wide variety of applications. Because XML is extensible, it can be used to describe data contained in a wide variety of applications, from describing collections of Web pages to data records. Because the data is self-describing, data can be received and processed without the need for a built-in description of the data.


• It improves performance through granular updates. XML enables granular updating. Developers do not have to send the entire structured data set each time there is a change. With granular updating, only the changed element must be sent from the server to the client. The changed data can be presented without the need to refresh the entire page or table.
