Web.Config transform question. Connection Strings

Say I have this in Dev
<connectionStrings>
   <add name="MyConnection" connectionString="yadayada" provider="blahblah"
</connectionStrings>

Upon Deployment to QA I need to transform that into below, how do I do that? I tried to xdt:Transform="Replace" but that wraps <connectionStrings xdt:Transform="Replace" around what I want to be the new connectionString element.

Thanks, John

<connectionStrings configProtectionProvider="RsaProtectedConfigurationProvider">
    <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element" xmlns="http://www.w3.org/2001/04/xmlenc#">
