I'm hoping you can recommend a tool that will allow me to convert HTML pages to XHTML. I have a pretty large magazine-type site (250 pages or so) so am hoping not to have to do it manually.

If you know of a good program to do this, I'd love to know about it. Thanks so much.

Why do you even need to?

Just try this source.

c:\temp>tidy -help

-help-config list all configuration options
-xml-config list all configuration options in XML format

Use --blah blarg for any configuration option "blah" with argument "blarg"

Input/Output default to stdin/stdout respectively
Single letter options apart from -f may be combined
as in: tidy -f errs.txt -imu foo.html

Well here are the things you need to fix to convert to xhtml

• have a <!DOCTYPE> element at the very first of the document
• make all tags lowercase. ex: <TD> is not XHTML valid tag instead use <td>
• make sure to close properly all tags for example <br> is valid HTML tag but not valid in XHTML. instead use <br /> or <br></br>
• Attribute values must be quoted ex. don't use <input checked> instead use <input checked="checked" />
• after finished try checking your document using http://validator.w3.org/ to see if it is valid xhtml document or not
