Hi Thilak,
There are several web techniques that used properly will decrease download time on large document masses, as well as server processing. To mention a few ow these used today:
Stylesheets (like CSS), dynamic HTML, client-side scripting, downloadable components and, the latest shot on the tree, XML with XSL.
XML supports all of the mentioned techniques, in addition to being one itself, but download time when it concerns plain text is seldom a problem unless we are talking about really large masses. XML/XSL (and the other techniques as well) are rather developed to help separate
content from
presentation. This makes it easier to develop websites and other forms of presentation, as content and presentation can be developed independently (for instance in the publishing industry). This also speeds up download, as you (ideally) only download the stylesheets once, and for every subsequent page only the raw content with no formatting.
I could make a list of sites using the combination XML/XSL/CSS as long as a bad year for you here, but you can easily make one yorself; the benefits from this separation have made the use of these technologies widespread despite it's low age; just do a search on those words in a popular search engine. (You found
this site)
