extract an element from json Array

[SPulivarthi]

Hi,

I'm trying to extract an element from a json array.

example:
{
"wait_time": 10,
"allocation": "net",
"values": [
{
"a": 1,
"b":2,
"c":3
},
{
"a": 81,
"b":75,
"c":57
},
{
"a": 43,
"b":77,
"c":92
},
{
"a": 55,
"b":24,
"c":32
},
{
"a":81,
"b":27,
"c":31
}
]
}

now I need all the 'b' values from the array. Is there any API which can handle this requirement
path=values[].b or path=values[*].b

now the API should return {2,75,77,24,27}
