这是我最终需要的 XML 格式..

<cms:MessageHeader>
<cms:MessageType></cms:MessageType>
    <cms:CreatedTimeStamp> </cms:CreatedTimeStamp>
    <cms:MessageIdentification> </cms:MessageIdentification>    
    <cms:PhysicalSender> </cms:PhysicalSender>  
<cms:PhysicalReceiver>  </cms:PhysicalReceiver> 
</cms:MessageHeader>

<cms:Process>
    <cms:Role></cms:Role>
    <cms:Processidentification></cms:Processidentification>
</cms:Process>

<cms:TransactionAcknowledgement>
    <cms:TransactionIdentification></cms:TransactionIdentification> 
    <cms:OriginalTransactionIdentification></cms:OriginalTransactionIdentification>
    <cms:TransactionAcceptance></cms:TransactionAcceptance>
    <cms:ResponseCode></cms:ResponseCode>
    <cms:TransactionAcceptance> </cms:TransactionAcceptance>
</cms:TransactionAcknowledgement>

输入的json是：

【问题讨论】：

你试过什么？（Stackoverflow 不是编码服务。）XSLT 3.0 绝对可以做到这一点；您使用的是支持 3.0 的处理器吗？

你可以在这里找到很好的解释：

【解决方案2】：

一种方法是使用 XSLT 3.0（例如 Saxon 9.8）中的 json-to-xml() 函数，然后将生成的 XML 转换为所需的格式。结果

json-to-xml(unparsed-text('file:///.../test.json'))

在您的输入开始时

<map xmlns="http://www.w3.org/2005/xpath-functions">
   <string key="name">Message</string>
   <string key="type">MESSAGE</string>
   <array key="attributes">
      <map>
         <string key="name">ExternalMessageType</string>
         <string key="value">Acknowledgement</string>
      </map>
      <map>
         <string key="name">MessageTimestamp</string>
         <string key="value">2017-02-10 11:35:07.595</string>
      </map>
      <map>
         <string key="name">PhysicalSender</string>
         <string key="value">8700000000001</string>
      </map>

您可以使用通用规则来转换它，例如

<xsl:template match="fn:map[*[@key='name'][. castable as xs:NCName] and *[@key='value']">
  <xsl:element name="{*[@key='name']}">{*[@key='value']}</xsl:element>
</xsl:template>

或使用更专业的规则，例如

<xsl:template match="fn:map[*[@key='name'][.='MessageTimeStamp']]">
  <time value="{xs:dateTime(translate(*[@key='value'], ' ', 'T'))}"/>
</xsl:template>
