VCard 4.0 Phones Regex?

我想读取VCard 4.0文件。

我用这个样品。

但是当我对这个文件使用这个解决方案时。

它找不到电话参数-例如，我用这个Regex作为电话号码：

 RegexOptions options = RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace;
    regex = new Regex(@"('n(?<strElement>(TEL)) (;*(?<strAttr>(HOME|WORK)))* (;(?<strType>(VOICE|CELL|PAGER|MSG|FAX)))*  (;(?<strPref>(PREF)))* (;[^:]*)*  (:(?<strValue>[^'n'r]*)))", options);

 mc = regex.Matches(s);
            if (mc.Count > 0)
            {
                Phones = new Phone[mc.Count];
                for (int i = 0; i < mc.Count; i++)
                {
                    m = mc[i];
                    Phones[i].number = m.Groups["strValue"].Value;
                    ss = m.Groups["strAttr"].Value;
                    if (ss == "HOME")
                        Phones[i].homeWorkType = HomeWorkType.home;
                    else if (ss == "WORK")
                        Phones[i].homeWorkType = HomeWorkType.work;
                    if (m.Groups["strPref"].Value == "PREF")
                        Phones[i].pref = true;
                    ss = m.Groups["strType"].Value;
                    if (ss == "VOICE")
                        Phones[i].phoneType = PhoneType.VOICE;
                    else if (ss == "CELL")
                        Phones[i].phoneType = PhoneType.CELL;
                    else if (ss == "PAGER")
                        Phones[i].phoneType = PhoneType.PAGER;
                    else if (ss == "MSG")
                        Phones[i].phoneType = PhoneType.MSG;
                    else if (ss == "FAX")
                        Phones[i].phoneType = PhoneType.FAX;

                }
            }

但strAttr、strType的值为空。

如何为这些设置Regex？
