Question

我正在尝试根据其架构验证Xml文件。这是我的代码：

 private readonly List<string> validationErrors = new List<string>();

 public bool TryValidate(string xml, string schemaLocation, ref List<string> errors)
    {          
        var document = new XmlDocument();
        document.LoadXml(xml);

        var schemaReader = new XmlTextReader(schemaLocation);

        var settings = new XmlReaderSettings {CloseInput = true};
        settings.ValidationEventHandler += Handler;
        settings.ValidationType = ValidationType.Schema;
        settings.Schemas.Add(null, schemaReader);

        var stringReader = new StringReader(xml);

        using (var validatingReader = XmlReader.Create(stringReader, settings))
        {
            while (validatingReader.Read())
            {
            }
        }

        errors = validationErrors;

        return errors.Count == 0;
    }

    private const string Format = "Line: {0}, Position: {1} \"{2}\"";
    private void Handler(object sender, ValidationEventArgs e)
    {
        if (e.Severity != XmlSeverityType.Error)
        {
            return;
        }

        validationErrors.Add(string.Format(Format,
                                           e.Exception.LineNumber,
                                           e.Exception.LinePosition,
                                           e.Exception.Message));

    }

架构对BusinessType元素具有以下限制：

        <xs:element name="BusinessType">                                              
            <xs:simpleType>                                              
            <xs:restriction base="xs:string">                                        
            <xs:maxLength value="15"/>                                               
            <xs:enumeration value="not specified"/>                                                  
            <xs:enumeration value="Sole trader"/>                                                
            <xs:enumeration value="Partnership"/>
            <xs:enumeration value="Limited company"/>                                                    
            </xs:restriction>                                        
            </xs:simpleType>
            <xs:element>

但实际的Xml实例文件包含其中包含零的元素：

          <BusinessType>0</BusinessType>

然而，当我运行验证代码时，它会通过模式验证（即没有发现错误）？编辑 - 作为测试，我也完全重命名了其中一个元素，但它仍然没有生成错误！

有谁知道为什么会这样？

非常感谢
