我有这个设置代码：

Dim settings As XmlWriterSettings = New XmlWriterSettings()
            settings.Indent = True
            settings.OmitXmlDeclaration = True
            settings.NewLineOnAttributes = True

然后我有这个作家的代码：

Dim xml As New XmlTextWriter(Server.MapPath("output.xml"), enc)

请你能告诉我如何使设置适用于作家吗？

非常感谢，菲尔。

编辑：代码示例

Sub writexml_OnClick(ByVal sender As Object, ByVal e As EventArgs)
    Try
        'Vars
        Dim securityid As String = Input_securityid.Text
        Dim enc As Encoding 

        Dim settings As XmlWriterSettings = New XmlWriterSettings()
        settings.Indent = True
        settings.OmitXmlDeclaration = True
        settings.NewLineOnAttributes = True
        settings.Encoding = enc

        'Declare the writer and set file name / settings
        Dim xml As XmlWriter = XmlWriter.Create(Server.MapPath("output.xml"), settings)

        'start document
        xml.WriteStartDocument()
        xml.WriteComment("")

        'start envelope
        xml.WriteStartElement("soap", "Envelope", "http://schemas.xmlsoap.org/soap/envelope/")
        'start body
        xml.WriteStartElement("soap", "Body", Nothing)
        xml.WriteAttributeString("xmlns", "ns1", Nothing, "http://its/foo.wsdl")

        'start biographical capture
        xml.WriteStartElement("ns1:biographicalcaptureElement")

        'start securityid
        xml.WriteStartElement("ns1:securityid")
        xml.WriteValue(securityid)
        'end securityid 
        xml.WriteEndElement()

        'start requestdata 
        xml.WriteStartElement("ns1:requestdata")

        'end requestdata
        xml.WriteEndElement()
        'end biographical capture
        xml.WriteEndElement()

        'end body
        xml.WriteEndElement()
        'end envelope
        xml.WriteEndElement()
        'end document 
        xml.WriteEndDocument()

        'clean up
        xml.Flush()
        xml.Close()

    Catch ex As Exception
        errorlbl.Text = ex.ToString
    Finally
        errorlbl.Text = ("Created file ok")
    End Try


    End Sub

如果我使用它确实可以正常工作；

Dim xml As New XmlTextWriter(Server.MapPath("output.xml"), enc)

生成了 xml，但未应用设置。

这不会让你得到一个XmlTextWriter，但老实说，我XmlWriter在写入文件时总是使用（XmlWriter是的基类XmlTextWriter。）

你可以使用XmlWriter.Create(Server.MapPath("output.xml"), settings)which 会给你一个XmlWriter而不是一个XmlTextWriter. 然后需要在您的设置实例中设置您的编码 ( settings.Encoding = enc.)

编辑：

为我提供的示例代码产生：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body xmlns:ns1="http://its/foo.wsdl" />
</soap:Envelope>

编辑2：

您的命名空间引起了问题，因为它试图将元素名称放在ns1:securityid应该是元素名称securityid和命名空间的位置ns1。您需要像在WriteAttributeString通话中所做的那样将它们分开，如下所示：

而不是：xml.WriteStartElement("ns1:biographicalcaptureElement") 使用：xml.WriteStartElement("biographicalcaptureElement", "ns1")

有了这些变化，我现在得到：

<!---->
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body xmlns:ns1="http://its/foo.wsdl">
    <biographicalcaptureElement xmlns="ns1">
      <securityid>TEST123</securityid>
      <requestdata />
    </biographicalcaptureElement>
  </soap:Body>
</soap:Envelope>
