At that point the data in the page that is about to be rendered is still in your webpage. It's accessible at adrPageTable^.adrObject^.

Actually, pagefilter would be appropriate. In pagefilter, adrPageTable^.bodytext is the body of your page, minus directives. No process has been done.

This all happens in html.buildObject (). Here's a summary of what happens:

build pagetable

handle binary objects

*firstfilter

render Object (this runs all directives and returns the page text minus directives)

double-check file path related directives

*pagefilter

insert pagetext into the template

process macros

handle relative addresses

add the #pageheader template

add fatpage comment

*finalfilter
