A case of "why didn't I do this sooner" when I saw this post on the Tinderbox wiki about auto-generating a Google Sitemap. I modified the provided templates a bit because I wanted to fill in some of the optional attributes. As suggested, I use an agent to collect exported notes with the following templates:

<?xml version='1.0' encoding='UTF-8'?>

<urlset xmlns="http://www.google.com/schemas/sitemap/0.84"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation= "http://www.google.com/schemas/sitemap/0.84

http://www.google.com/schemas/sitemap/0.84/sitemap.xsd">

^children(sitemap-item.xml)^

</urlset>

and

<url>

<loc>^urlEncode(^URL^)^</loc>

<lastmod>^Get(Modified, =)^</lastmod>

<priority>^Get(GoogleSitemapPriority)^</priority>

<changefreq>^Get(GoogleSitemapChangeFreq)^</changefreq>

</url>

The change I made to this is to suck out the priority and change frequency from attributes. One nifty aspect of Tinderbox is that I can apply some defaults (say GoogleSitemapPriority of .5) and then override this so certain pages have a higher priority. Works like a charm and now I don't have to worry about mucking around with one of those perl sitemap builders...

Kudos to the Tinderbox community for continually finding neat things to do with this program.
