Setting properties at test case level from request

Thanks EmBear

But my requirement is somewhat different. We cannot assume

My request can be as below also

 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:webs="http://webs">
       <soapenv:Header/>
       <soapenv:Body>
          <webs:SaveFilePropertiesRequest>
             <webs:SystemUserCredentials>
                <webs:UserID>userIDValue</webs:UserID>
                <webs:UserPassword>userPasswordValue</webs:UserPassword>
                <webs:SystemDomain>systemDomainValue</webs:SystemDomain>
             </webs:SystemUserCredentials>
             <webs:PropertiesToBeSaved>
             <webs:File>
                <webs:FileName>fileNameValue#1</webs:FileName>
                <webs:FilePath>filePathValue#1</webs:FilePath>
                <webs:FileType>fileTypeValue#1</webs:FileType>
                <webs:FileSize>fileSizeValue#1</webs:FileSize>
             </webs:File>
             <webs:File>
                <webs:FileName>fileNameValue#2</webs:FileName>
                <webs:FilePath>filePathValue#2</webs:FilePath>
                <webs:FileType>fileTypeValue#2</webs:FileType>
                <webs:FileSize/>
             </webs:File>
             </webs:PropertiesToBeSaved>
          </webs:SaveFilePropertiesRequest>
       </soapenv:Body>
    </soapenv:Envelope>

For this request I need to save properties as below:

UserID
UserPassword
SystemDomain
FileName#1
FilePath#1
FileType#1
FileSize#1
FileName#2
FilePath#2
FileType#2
FileSize#2

I expect to not set any manual value like "cloud" in the code(except #1....#n. This can be adjudged by #i). Code should automatically extract these values and set them as a property.
