XML 元素值作为 SOAP 正文标记属性值

问：

作为初学者，我遇到了一个问题，我必须将消息 ID 标签值作为 Soap Body 的 wsu ID 动态传递，而不是静态传递（到目前为止我一直在这样做。

请帮助实现这一目标。

<?xml version="1.0" encoding="UTF-8"?>
<root>
   <ebms:Messaging xmlns:ebms="http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/ns/core/200704/">
      <ebms:UserMessage>
         <ebms:MessageInfo>
            <ebms:Timestamp>02-11-2023T12:41:11</ebms:Timestamp>
            <ebms:MessageId>Body-4652f446-e7f8-4749-b8e2-630d192d521a</ebms:MessageId>
         </ebms:MessageInfo>
         <ebms:CollaborationInfo>
            <ebms:Service type="BATCH">BUPLRQ</ebms:Service>
            <ebms:Action>UploadMsg</ebms:Action>
            <ebms:ConversationId/>
         </ebms:CollaborationInfo>
      </ebms:UserMessage>
   </ebms:Messaging>
   <UploadMsgRq>
      <FileType>xml</FileType>
      <AsyncRqUID/>
      <Attachment>no attachment found20231102124111</Attachment>
   </UploadMsgRq>
</root>

下面是我用来创建 SOAP Envelop 的代码，其中将静态值传递给 WSU ID SOAP BODY 标记

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

   <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

   <xsl:template match="/">
      <soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ebms="http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/ns/core/200704/" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
         <soap:Header>
            <xsl:copy-of select="*//ebms:Messaging"/>
         </soap:Header>
         <soap:Body wsu:Id="Body-4652f446-e7f8-4749-b8e2-630d192d521a" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
            <xsl:copy-of select="*//UploadMsgRq"/>
         </soap:Body>
      </soap:Envelope>
   </xsl:template>
</xsl:stylesheet>
