There used to be a substandard one in DW but it was removed a couple of versions ago. I assume in response to user feedback on who was using the feature.
I never use site maps myself. But others obviously do.
That's not entirely true. As you can see here http://386solutions.com/enable-siteMap_dreamweaver.html, it's just been disabled. Reenable with registry, in
HKEY_CURRENT_USER\Software\Adobe\Dreamweaver CS5\Feature Management
the value is sitemap = false, make it true
and you can do it in mac too: http://www.youtube.com/watch?v=60cbfLm5pDg
The OP is specifically asking about creating a sitemap to submit to Google (aka an XML sitemap). The post you reference talks about enabling the old Dreamweaver visual sitemap. It doesn't look like that DW feature can generate an XML sitemap.
Oh well, I guess a third-party tool is the only solution.
that's ok. It's Sept. 16, 2013 and I am looking for this information. I remember sitemapping in a previous version of DWR and would like to start doing this again.
Try this Free Dreamweaver (exchange) extension called Ordinary Site Map.
Once the extension is added (installed thru Extension Manager) it will generate a site map html page page with sitewide html doc file names and links in CSS formatting.
It is simple to use and works with Dreamweaver CS5.5
You may want to change the doc file names to each specific page summary name. Ex. "index.htm" to "Home Page", etc. But not much more work is needed.
*Also you may have to do a "find and replace" in the document to change the source code ":" to "/" for the links to work after putting the page to the server.
