XML API - Need to replace services for a security rule via XML api - currently api call is appending new port

[MikeBaranski]

Hi - I create a service (tcp-443) and then create a security rule that uses this service as the service member.

This works.

Then, if I call the same API call with the same xpath and provide a different service, say tcp-449, the resulting security rule has *both* tcp-443 and tcp-449 in the Service column:

First call is <service>["tcp-443"]</service>

Second call is <service>["tcp-449"]</service> 

xpath: `/config/devices/entry[@name='localhost.localdomain']/device-group/entry[@name='${ deviceGroup }']/${ rulebase }/security/rules/entry[@name='${ entryName }']`

I would like the second call to replace "tcp-443" with "tcp-449" - what it is doing is appending "tcp-449" to the services. Can I do that without deleting the security rule and re-adding it?
