CSS parser that counts the number of css errors while parsing

Is there a CSS parser in .NET that counts the number of syntax errors in css while parsing it? I have tried http://www.devtriogroup.com/HtmlParser/CssParser.aspx .  It parses the css but does not tell you if the css has any errors or give an error count.  It builds a tree from the css tags.  If the css has errors such as a missing }, it will interpret the next two tags as attributes and then stop.  I need to check in my code if the css has any errors and prevent the user from saving the css document if there are any errors.
