PHP solution to sanitize user formatted input and make XHTML Strict compliant

What are best solutions for making user formatted input

1. safe + script/fla开发者_StackOverflowsh free
2. XHTML Strict compliant

Tidy converts HTML to XHTML Strict. Any similar/alternative options that does this plus sanitizes and removes embedded scripts and flash?

Not sure if this is what you are looking for but I tend to use htmlPurifier.
