    XML(http://en.wikipedia.org/wiki/XML) is all about computers talking to computers. XML stands for Extensible Markup Language which is all about describing data. XML allows data (Webpages or whatever) to be described in "extensible" language which allows for something like this.

    As long as both computers (or even people) know what my_question means they can work with that information to build something else.

    I would check out the Wikipedia entry for all the info you need.

    I hope that helps!

    XML (Extensible Markup Language) allows information to be encoded with meaningful structure that computers and humans can understand. XML is great for information exchange, and can easily be extended to include user-specified and industry-specified tags.

    more…
    -XML was designed to describe data
    -XML tags are not predefined. You must define your own tags
    -XML uses a Document Type Definition (DTD) or an XML Schema to describe the data
    -XML with a DTD or XML Schema is designed to be self-descriptive

    want to know more search yahoo/google..:)

    XML stands for Extensible Markup Language. It’s called extensible because it can be configured to serve almost any function you’d like to apply to it. By creating tags, you can mark up text and give it meaning.

    For example:

    <name> John Smith </name>
    <birthday> January 31, 1950 </birthday>
    <occupation> programmer-analyst </occupation>

    Like any markup language, these tags and text don’t do anything on their own unless they’re parsed or read by a program that can properly interpret the tags and process the information in a useful way.

    XML in the form of RSS can create subscriptions to web pages or data can be exported from a software program and be reused in another by using a common XML format. Its uses and applications are only limited by people’s imagination.
