I splitted one web page as header,Leftnav,rightnav, body and footer(For templating work). For these all i created xsd and related xsl files. My requirement is to include all in one page to see the entire preview. For that i am trying to include all in body part. but i am not.
Tell me the process how to include all in single page. This is little bit urgent.
"Fry" the page at request time by using delivery side techniques to composite the page from it's constituent assets. The exact technique depends on your delivery side technology, but includes things like server side includes (web servers), <jsp:include> (Java app servers), <!–#include file="…"–> (ASP.NET), include '…' (PHP), etc.
Note that with the first option it's not possible (in the general case) to track all of the dependencies between the source assets and the final composited page, so you will eventually find yourself having to manually regenerate pages when certain source assets change. For that reason I personally prefer the latter approach (delivery time page composition), since each page can have arbitrarily complex dependency graphs without anyone ever having to worry about stale content appearing in those pages.
Yep - Tiles is one example (amongst many!) of the "fry" model (which is the one I tend to favour, given the dependency management problems that can occur with the "bake" model).
