求助XmlReaderSettings和XmlValidatingReader进行xml与xsd文件校验时的问题

            XmlValidatingReader进行xml与xsd文件校验
            FileStream stream = new FileStream(xmlPath, FileMode.Open);
            XmlValidatingReader vr = new XmlValidatingReader(stream, XmlNodeType.Element, null);
            vr.Schemas.Add(xmlNameSpace, xsdPath);
            vr.ValidationType = ValidationType.Schema;
          
            vr.EntityHandling = EntityHandling.ExpandEntities;
            vr.ValidationEventHandler += new ValidationEventHandler(ValidationHandler);
            while (vr.Read()) ;            XmlReaderSettings进行xml与xsd文件校验            XmlReaderSettings settings = new XmlReaderSettings();
            settings.ValidationType = ValidationType.Schema;
            settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
            settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
            settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
            settings.ValidationFlags |= XmlSchemaValidationFlags.AllowXmlAttributes;            settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);            XmlReader reader = XmlReader.Create(xmlPath, settings);            while (reader.Read()) ;两种方法校验都有一个问题，就是如果xml文件中缺少n个节点（大于等于2），而数据的结果只能显示第1个问题，后面的无法显示，请高手指点如何解决，谢谢。我希望可以把xml文件中缺少的所有节点找出来。
