Regarding Generic parser implementation

[vjain641]

Hi,

I want to implement a generic rest parser.
I was going through the rapidjson library & found it very useful.
My requirement is to parse a really big complex json file & extract the values provided as the arguments in c++. Lets say following is an excerpt from my json file :

{
"states": {
"entry": [
{
"key": "ENTITY",
"value": {
"barring": false,
"id": "DefaultDeviceLifeCycle_Active",
"initial": true,
"name": "Active",
"final": false }
}
]
}
}

Parameters like states:entry:value:id would be provided & I want to return the value of id tag.

Can you please provide some pointers on it that how can it be implemented??
