How to create a customized request?

[Jan]

Hi,
I want to use SOAP::Lite as a SOAP client to create requests like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:ecom="https://ecomm.sella.it/">
   <soapenv:Header/>
   <soapenv:Body>
      <ecom:Encrypt>
         <ecom:shopLogin>user83943</ecom:shopLogin>
         <ecom:uicCode>242</ecom:uicCode>
         <ecom:amount>0.05</ecom:amount>
         <ecom:shopTransactionId>63789</ecom:shopTransactionId>
         ... some more parameters ...
      </ecom:Encrypt>
   </soapenv:Body>
</soapenv:Envelope>

How can this be done? Is it possible with SOAP::Lite?
I didn't even find a way to manipulate the envelope according to this structure.

Whatever I try, I always get something like this:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Body>
          <Encrypt>
              <shopLogin xsi:type="xsd:string">user83943</shopLogin>
              <uicCode xsi:type="xsd:int">242</uicCode>
              <amount xsi:type="xsd:float">0.05</amount>
              <shopTransactionId xsi:type="xsd:int">63789</shopTransactionId>
              ... some more parameters ...
          </Encrypt>
      </soap:Body>
</soap:Envelope>

But this is not accepted by the server.
