A little dynamic in my sites and other

I have a main template designed and ready to go, and in that design is a table where the text resides, in normal cases if a page was to continue from that i.e more information that could not fit on that page I would have created a seperate page.

I understand there is a method using dynamics to avoid all that extra work. But not entirely sure how.

If say I had an empty table, and included an include file inside that table this would work, but lets say I required a next and previous. How could I achieve this without developing two seperate pages. Whereby just the table content is changed on clicking the next button.

Hope this makes sense.

A second thought was the use of XML, which I am not entirely sure of its advantages, but would appreciate any feedback on this
