Having trouble validating code block...

When I attempt to validate the below code block I receive two errors.  What exactly am I supposed to do to correct this issue?
Line 10, Column 6: document type does not allow element "body" here <body>Line 24,        Column 7:     end tag for "html" which is not finished     </html><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
