Generate a "site map" from hierarchical list of pages

I use a hierarchical numbering system to identify pages when I inventory a web site.  This system is based on where the pages are linked (starting from the home page).  I store my page lists in Excel or Access.

The page ID system works like this:  The page linked to the first link on the home page is identified as page 1 and the page linked to the second link on the home page is page 2.  The page linked to first link on page 1 is identified as 1.1.  The page linked to first link on page 2 is identified as 2.1. and so on. (Since I like to sort these IDs, I use two digits before every period, e.g., 01.01 or 02.01, or else 1.10 would fall before than 1.2)

Could I use this numbering system to create something like a site map?  Perhaps by using the number of periods to insert an appropriate number of tabs before the name of each page on a print out of the site's pages.  That might not print well for a really deep site, though.

I've used Mind Manager to make mind maps shaped like org charts.  Any ideas for exporting this to Mind Manager perhaps to make a mind map or any other org chart kind of tool?

Any ideas?
