XML and HTML

XML and HTML are so similar that if you have learned HTML, then you basicly already know XML. The major difference is that in XML you can define your own tags--and the tags are defined in the style sheet.

Why its important to learn HTML first is that in some situations, like posting in forums for instance, we cant define our own tags so we need a predefine set of tags and HTML offers that. Being able to define your own tags also gives you an added flexibility that HTML does not offer, in that your not limited to the predefine set.

Unlike HTML, XML is used in applications outside the internet but this is not what I intend this site to be about.
