Hi,

In my specific scenario I’m creating a bunch of ec2 security groups using with\_items, I’m using the register task to pick up the result.  
The resulting variable, as expected contains the information for each security group, I would like to obtain just the security group id’s and shove those in a list variable.

Any ideas?

Thanks,  
Nico
