English In this lecture you will learn what XML is. XML stands for Extensible Markup Language. As the name itself says we can create our own markup required for our business purposes using XML. If you are familiar with HTML then you know that HTML provides a predefined set of elements that add special meaning to the data that they wrap. For example, John here in bold surrounded by the b tags, HTML tags will be interpreted by the web browsers like Internet Explorer, Chrome and Firefox in bold. H1 will display this text here, Welcome To The World of XML in a slightly bigger font and in bold. So HTML adds a special meaning to the data or it adds presentation value to the date it wraps and it has a predefined set of elements. Whereas XML doesn't have any predefined set of elements. It allows us to create our own XML. Using XML we can define our own markup. For example, if we are working on Ecommerce application, we can create a OrderML which will have the OrderId, LineItems, ShippingAddress and all that we need for the order data. Similarly if we are working on a news portal, then we can create a NewsML which can carry the Headlines, Politics information, political information or political news as well as Sports data. Applications can then use this XML to save it, to manipulate and display it to the end user or even to exchange this information with other applications. That is the power of XML. To summarize, XML which stands for Extensible Markup Language unlike HTML, it doesn't have any predefined set of elements. It allows us to create our own markup language or markup elements so that our applications can use the data however they want and they can do whatever they want to do with that data very easily.
