Trying to validate pages as XHTML strict

Are there any programs out there that can help me clean up my web pages so that they can validate? <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=6928&image=1&table=forumreplies' class='bbc_emoticon' alt=':blink:' /> <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=6928&image=2&table=forumreplies' class='bbc_emoticon' alt=':)' />

Are you talking about the phprunner generated page?

If you are trying to validate phprunner generated page as XHTML strict, it is lot of work.

I changed and cleaned up the style sheet and then, I carefully cleaned up the html pages one by one and used xhtml transitional doc type head.

I am not sure I can validate the pages coded with PHP/html.
I don't know any program that'll clean up the XHTM strict page but you can validate your page to see what mistakes you made and change accordingly, no easy answer here.
