루트 요소에 xmlns를 포함하도록 XslCompiledTransform을 얻는 방법은 무엇입니까?

XslCompiledTransform C # 클래스를 사용하여 하나의 xml 파일을 다른 파일로 변환하려고합니다. 그러나 xmlns 속성은 전송되지 않습니다.

내 코드 :

XmlReader reader = XmlReader.Create("machine1.xml");
XmlWriter writer = XmlWriter.Create("machine2.xml");

XslCompiledTransform transform = new XslCompiledTransform();
transform.Load("transform.xsl");

transform.Transform(reader, writer);

XSLT :

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns="http://schemas.datacontract.org/2004/07/CMachines" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" />
  <!-- Copy everything not subject to the exceptions below -->
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()" />
    </xsl:copy>
  </xsl:template>
  <!-- Ignore the disabled element -->
  <xsl:template match="Disabled" />
</xsl:stylesheet>

입력:

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfMachine xmlns="http://schemas.datacontract.org/2004/07/CMachines" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <Machine>
      <Name>DellM7600</Name>
      <ID>1</ID>
      <Type>Laptop</Type>
      <Disabled>false</Disabled>
      <SerialNum>47280420</SerialNum>
    </Machine>
    <Machine>
      <Name>DellD600</Name>
      <ID>2</ID>
      <Type>Laptop</Type>
      <Disabled>false</Disabled>
      <SerialNum>53338123</SerialNum>
    </Machine>
    </ArrayOfMachine>

이것은 실제 출력입니다.

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfMachine xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/CMachines" >
    <Machine>
      <Name>DellM7600</Name>
      <ID>1</ID>
      <Type>Laptop</Type>
      <Disabled>false</Disabled>
      <SerialNum>47280420</SerialNum>
    </Machine>
    <Machine>
      <Name>DellD600</Name>
      <ID>2</ID>
      <Type>Laptop</Type>
      <Disabled>false</Disabled>
      <SerialNum>53338123</SerialNum>
    </Machine>
    </ArrayOfMachine>

다음은 원하는 출력입니다.

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfMachine xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/CMachines" >
    <Machine>
      <Name>DellM7600</Name>
      <ID>1</ID>
      <Type>Laptop</Type>
      <SerialNum>47280420</SerialNum>
    </Machine>
    <Machine>
      <Name>DellD600</Name>
      <ID>2</ID>
      <Type>Laptop</Type>
      <SerialNum>53338123</SerialNum>
    </Machine>
    </ArrayOfMachine>
