    Purpose of XML is to store date in a structured format so that it can be parsed and manipulated programatically

    Its just structured data. It makes it easy to pass data around between applications. Its also very easy to use x-path to quickly extract a piece of information.

    Its also used extensively in the OSS / BSS worlds via North Bound Interfaces etc.

    XML is just a way of storing data. By using tags and sub tags you can give your data structure. Using parsers you can read data from xml files straight into your code easily.

    HTML combines data and formatting information.

    XML just contains data. You can use XSLT stylesheets if you want to display XML data in a web page. This allows separation between the data and the formatting.
