Hi,

I have got this hash

ok: [localhost] =\> {  
“msg”: {  
“123”: “hostname1”,  
“345”: “hostname2”  
}  
}

I would like to create a new list from the above hash which contains only the values .

- hostname1
- hostname2

When I use variable.keys() I get the first fields I would like all the second fields in a new list. Is this possible?

I got the hash after using combine().

Regards,  
Abey

Something like this:

values: "{{ msg | json\_query('\*') }}"

Hi Dick,

Thanks. That worked.

ok: [localhost] =\> {  
“msg”: [  
“hostname1”,  
“hostname1”  
]  
}

Never used JMESPath until now!
