Dreamweaver Convert Page to XHTML

How can I convert my entire site to XHTML using Dreamweaver

[riospace]

I need to convert all of the pages in my entire site to XHTML. I know how to convert a single page at a time in Dreamweaver, but is there a way to convert my entire site in Dreamweaver? Converting one page at a time will take forever as my website has over 5,000 pages.

Woah, lotsa pages! There might be an extension somewhere! Have you tried the DW forums?
