Well, to begin with, all tags should be lower case. <td> instead of <TD>.
And all properties MUST be enclosed in quotes, not apostrophes. <td class="whatever"> and not either <td class=whatever> or <td class='whatever'>.
& should be written & (because the & alone looks like the start of the & entity), etc.
Once you have converted the HTML, use the w3c validator to make sure it validates as strict XHTML.
If you have any errors, it will tell you about them so you can easily fix them and try again.

A pessimist sees the glass as half empty.
A realist drinks it no matter how much there is.
