Hi,

 where is your source? I supposed online, and I suppose with a REST api system, but you need to know exactly what system so that you can use something like DataMaker ( and the json support inside, as rest api usually send back data using json).

 Do you know DataMaker? Are you seasoned with PlayMaker already?

 Bye,

 Jean

Hi
sorry for late reply and thank you for help. I am familiar with playmaker and I have downloaded the datamaker as you suggested. I have also found a way how to get price data online. Im using WWW object to download crypto price and it looks like this.
https://api.coinmarketcap.com/v1/ticker/bitcoin/

[
    {
        "id": "bitcoin",
        "name": "Bitcoin",
        "symbol": "BTC",
        "rank": "1",
        "price_usd": "6508.55910592",
        "price_btc": "1.0",
        "24h_volume_usd": "3332581644.17",
        "market_cap_usd": "112812854983",
        "available_supply": "17333000.0",
        "total_supply": "17333000.0",
        "max_supply": "21000000.0",
        "percent_change_1h": "0.44",
        "percent_change_24h": "0.72",
        "percent_change_7d": "3.27",
        "last_updated": "1540087351"
    }
]

Can you please tell me how to setup xPath to be able to extract all those values as a float?

Hi,

 this is a json, not an xml, so you will need to get to your data manually, by navigating node by node inside your json.

 We've found with djaydino a new version of a xml json library that exposes a lot of new features, and I'll be starting implementing them very soon, including a jpath variant :) and json to xml conversion.

Bye,

 Jean
