What is XML? I am a programming student and so far I have done HTML, C, C++, Java and I just started SQL. I know I am supposed to do XML by the end of the course, but right now I dont have a clue what it is all about. I would like to know what XML is all about and if it is similar to any of the languages I have covered so far. Could someone who knows the answer to these questions please answer them for me.
Thanks in Advance.

XML is a programming language used to reprsent data, independent of platform. This XML file is used with an XSL file (style specific information) to get a html file.
There are very good tutorials on xml at. http://www-106.ibm.com/developerworks/education/xmlintro

Hi Tisha,
XML is a specification for writing markup languages. You could write the HTML language using the XML specification, and in fact there is a new version of HTML that conforms to the XML specification called XHTML at the W3C (www.w3.org).
The reason it's so popular is that anyone can make up any language they like, and if another person, company, organization, or other entity wants to read that language, as long as they can read XML they will be OK. Even better, if the XML DTD or Schema is available, they can actually understand a lot about what the tags mean, even if they've never seen them before. That's why it's called a self-describing language.
And if enough definition data is provided, you might even be able to setup a server that can interpret an XML language for you, well enough to perform fairly complex actions on your behalf. For example, ordering products automatically when the price and terms are right, no matter who the manufacturer is, as long as their ordering system uses XML.
Hope this helps
