Advantages:
> XML is used for organizing.
> XML has a language markup just like HTML, using tags and whatnot.
> The tags are made up by the user (So
memorization is required.
> XML is commonly used for RSS feeds, and other feeds accepting XML. It is a simple way to streamline news and updates.
Disadvantages:
~ XML does not "build" like HTML does.
~ XML is just a bunch of tags and words until put into a feed that churns XML into user-friendly data.
~ CSS cannot design XML, since XML does not initially "output" anything but the raw source.
dHTML
Advantages:
> dHTML is the combination of JavaScript, HTML, and CSS to make dynamic user interfaces, such as web navigation menus and user-friendly maps of a sort.
> dHTML is not a new language, so there's no more memorization needed.
Disadvantages:
~ dHTML uses JavaScript, which is sometimes disabled on web browsers (And CSS, which could be turned off, but rarely is).
~ Creating a dHTML interface is risky when it comes to browser-compatibility.
~ Many browsers tend to display different things when poorly constructed.
Conclusion:
I have mentioned all the important features as well as disadvantages of the above markup languages, even though each has several options, only the real-time website applications choose which one to be used and for what reasons. Choosing a perfect markup language improves a website quality and performance highly.
