I'd like to validate that users of my WPF application are putting proper XHTML into its TextBox control.
I found that there's an API for the W3C Markup Validator.
It's web page says:
Building of libraries used to interact with the validator's API is encouraged. …
and it lists known Perl, PHP/PEAR and ColdFusion libraries.
Does anyone know of a .NET library for the W3C Markup Validator API? Does one already exist?
