HTML validation/fix in C#

I n开发者_JS百科eed to check if a HTML document is correct, if all tags and attributes are ok (in C#). If not, try to fix malformed tags and/or attributes. Any suggestions for a library or tool that i can use?

Thanks.

Tidy Managed solved my problems. This tool knows to repair broken tags and to close tags. Build TidyManaged app and download the libtidy.dll file and place it in bin/debug file.
