Question

我正在尝试使用VB.net针对架构验证xml文件。我的问题是，与模式完全匹配的文件仍然没有错误传递。这是我正在使用的代码：

   Private Sub ValidateDelete(oStream As Stream, sExt As String)
        _DeleteErrorMessage = ""
        Dim XmlFileDoc As New XmlDocument
        Dim oSettings As XmlReaderSettings = New XmlReaderSettings()

        Dim scSet As New XmlSchemaSet
        Dim sSchemapath As String = AppSettings("DeleteSchemaFile")

        Using scRead As XmlReader = XmlReader.Create(New FileStream(sSchemapath, FileMode.Open, FileAccess.Read), Nothing, sSchemapath)
            scSet.Add(XmlSchema.Read(scRead, Nothing))

        End Using

        scSet.CompilationSettings = New XmlSchemaCompilationSettings
        scSet.Compile()

        oSettings.ValidationType = ValidationType.Schema
        oSettings.Schemas = scSet

        AddHandler oSettings.ValidationEventHandler, New ValidationEventHandler(AddressOf ValidationEventHandler)

        Dim oreader As XmlReader = XmlReader.Create(oStream, oSettings)

        Try
            XmlFileDoc.Load(oreader)

        Catch xex As XmlException
            _DeleteErrorMessage = xex.Message
            ValidXML = False

        Catch ex As Exception
            Throw ex
        Finally
            oreader.Close()
        End Try


    End Sub
    Private Sub ValidationEventHandler(ByVal sender As Object, ByVal e As ValidationEventArgs)

        If e.Severity = XmlSeverityType.Error Then
            _DeleteErrorMessage = e.Message
        End If

    End Sub

这是我正在验证的xsd文件。如您所见，它非常简单。

<?xml version="1.0" encoding="utf-8"?>

                    <xs:pattern value="[0-9][0-9][0-9][0-9]"></xs:pattern>
                  </xs:restriction>
                </xs:simpleType>
              </xs:element>

              <xs:element name="report-quarter">
                <xs:simpleType>
                  <xs:restriction base="xs:string">
                    <xs:length value="1"></xs:length>
                    <xs:pattern value="[1-4]"></xs:pattern>
                  </xs:restriction>

                </xs:simpleType>

              </xs:element>
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>

  </xs:element>
</xs:schema>

该文件允许客户从我们的系统中删除记录。如果我验证缺少元素或具有无效值的删除文件，它工作正常，我得到预期的错误消息。如果我验证一个不是删除文件的文件，我没有收到任何错误消息。它没有问题。

谁能告诉我这里我做错了什么？
