What is XML? How and where is it used in the websites?
I came across this: http://answers.yahoo.com/question/in...1235156AAZWUuN
This pretty much explains it but i am still confused. 'That it is sister language to HTML. This is where you can define your own tags, and it is used to move data from one place to other'.
Could you show me some working examples in websites how it is implemented? What is the alternate language to XML? Does it work with javascript?
