How to check if string has a correct html syntax

Question

I would like to check if a given string has a correct html syntax. I don't know which html elements should be inside, the only one thing I know is that string should be a correct html expression.

Anyone has an idea how to check it in C#?

You can use Html Agility Pack : http://html-agility-pack.net/?z=codeplex

string html = "<span>Hello world</sspan>";  HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(html);  if (doc.ParseErrors.Count() > 0) {    //Invalid HTML }
