You can use following XPath //*[@*[contains(., 'en-us')]] which selects any elements which have any attribute which contains string en-us:

HtmlDocument doc = new HtmlDocument();
doc.Load(path_to_html_file);    
var nodes = doc.DocumentNode.SelectNodes("//*[@*[contains(., 'en-us')]]");

Or LINQ way:

var nodes = doc.DocumentNode.Descendants()
               .Where(n => n.Attributes.Any(a => a.Value.Contains("en-us")));
