That is, it uses tags (eg. ) and we can assign attributes or properties to tags In XML we can define our own tags unlike it is the case in HTML where the tags are predefined for us. Using XML we can have presentation of data, description of data, and containment of data in the same page. That is we might want to define the tag 123 in which case we know that 123 is the price because it is describes as such. It is important to know that XML is not a replacement for HTML. Actually, XML is used for description and containment of data while HTML to present the data and the whole document.
