...XML???

XML is just a syntax for storing data. You make up tag names and give tags attributes and/or values. You can then read XML using either a program or with something called an XSL stylesheet and parse the data out using the tags, their attributes, and their values. For example, you could have an XML file that saves address book information. For example:

Code:

<xml> <addresses> <address> <name>John Smith</name> <street>123 Main St. Apt. 301</street> <city>Anytown</city> <state>NY</state> <zipcode>90210</zipcode> <country>USA</country> <address> </addresses> </xml>

This is a fairly straightforward answer. You may want to look up "XML tutorials" through yahoo or google or some other search engine for more help, or try some books on XML.
