SOAP receiver adapter error using Google Search web service

Question

Hi all,
I'm trying to connect and old 4.5b system to XI SP16 to make it receive information from external Web Services.
My scenario is made up of a sender RFC adapter and a SOAP receiver which is sending the message to the Google web service (http://api.google.com/GoogleSearch.wsdl) and then awaiting a response from it.
I'm stuck with this error: "No Deserializer found to deserialize a ':key'". The problem is that XI is sending this kind of message:
          <m:doGoogleSearch xmlns:m="urn:GoogleSearch" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
               <key>mykey</key>
               <q>testing</q>
               <start>0</start>
               <maxResults>1</maxResults>
               <filter>true</filter>
               <restrict>String</restrict>
               <safeSearch>true</safeSearch>
               <lr>String</lr>
               <ie>String</ie>
               <oe>String</oe>
          </m:doGoogleSearch>
while Google is expecting this:
          <m:doGoogleSearch xmlns:m="urn:GoogleSearch" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
               <key xsi:type="xsd:string">mykey</key>
               <q xsi:type="xsd:string">testing</q>
               <start xsi:type="xsd:int">0</start>
               <maxResults xsi:type="xsd:int">1</maxResults>
               <filter xsi:type="xsd:boolean">true</filter>
               <restrict xsi:type="xsd:string">String</restrict>
               <safeSearch xsi:type="xsd:boolean">true</safeSearch>
               <lr xsi:type="xsd:string">String</lr>
               <ie xsi:type="xsd:string">String</ie>
               <oe xsi:type="xsd:string">String</oe>
          </m:doGoogleSearch>
with explicitly declared xsi:type.
I've tested both messages with XMLSpy and the first one is always returning the same error.
Is there a way to make XI send an XML message with written xsi:type?
Many thanks in advance!

Hi Ricardo!
I followed your suggestion to create a simple XSLT mapping program (in the ABAP stack) and I added it to the Interface Mapping in the Integration Repository. The result is exactly the soap message that the Google web-service is expecting.
I'm attaching the XSLT code below in case somebody has the same problem... thanks again for your hint!!
