Looping in SOAPUI Pro

Hi,

I need help bcause I want to retrieve some information from the response to a Request.

My Request is like :

<soapenv  : Enveloppe url>

   <soapenv : Header/>

   <soapenv : Body>

      <con : getData>

         <NumClient>aaaa</CustNumber>

     </con...>

  </...>

...

And my Response like

<soapenv : Enveloê url>

   <Soapnv : Body>

     <ser-root:getDataResponse url>

        <PivotFichClient>

           <CodePtf>bbbb</CodePtf>

        </PivotFichClient>

        <PivotContrat>

           <NumContrat>123</NumContrat>

        </PivotContrat>

        <PivotContrat>

           <NumContrat>456</NumContrat>

        </PivotContrat>

        <tns3:GetFonds>....</tns3:GetFonds>

....

I want to retrieve every NumContrat in the Response.

The Response can return 3 rows "Pivot Contrat" with 3 numbers contrats or 2 or 4 ,... it depends of the NumClient.

 I've already declared a datasink with a properties list {NumClint, Ptf, NumContrat},

I've declared and Xpath which retrieved a NumContrat but just one and I don't know how many contract my customer have.

I want to make a loop but I don't know how to do.

Have you got a solution ?
