regex - Jmeter extracting fields/parsing JSON response

Question

I have following JSON format in response body

[
    {
        "Name" : "Prashant",
        "City" : "Sydney"
    },
    {
        "Name" : "Yogi",
        "City" : "London"
    }
]

What is the better way for checking if this array has any records and if yes give me "Name" for first array index. I am using jp@gc JSON extractor plugin for jMeter.

Is it possible to parse this using a plugin or do I need to do it using regular expressions?

Using Ubik Load Pack JSON plugin for JMeter which is part of JMeter since version 3.0 (donated plugin) and called JSON Extractor, you can do it:

And here is the run result:

So as you can see it is possible with plain JMeter
