推荐答案

internal static void RectifyXML()
        {
            //the path to the xml file
            string path = @"C:\CodeProject\test.xml";
            //create the xmldocument
            System.Xml.XmlDocument CXML = new System.Xml.XmlDocument();
            //load the xml into the XmlDocument
            CXML.Load(path);
            string correctedXMlString = Regex.Replace(CXML.InnerXml, @"[^\u0000-\u007F]", string.Empty);
            File.Delete(path);
            CXML.LoadXml(correctedXMlString);
            CXML.Save(path);
        }

var xmlPattern = "[^\u0001-\uD7FF\uE000-\uFFFD\ud800\udc00-\udbff\udfff]";

var newXml = xml.replace(new RegExp(xmlPattern , "g"), "");
