我是 SOAP 新手。如何生成如下所示的 SOAP 标头?
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<t:Transaction xmlns:t="xxs">
<tc>
<iden u="Test" p="TEMP001" city="code" role="Agent" />
<agent user="user1" />
<trace>trace001</trace>
<script name="test" />
</tc>
</t:Transaction>
</SOAP-ENV:Header>
</SOAP-ENV:Envelope>
