I am new to xml. After creating an xml file if i open the xml file in the browser, the code is displayed. my question is where does the functionality of xml come in, for example in case of php,asp,jsp they are server side scripts which processes details that are entered in a form. Does xml have the same functionality or is it different. please advice the 1. functionality of using an xml document. 2. how to execute the xml document in the browser 3. do i need to install any xml software to execute xml documents. Thanks.
