Answer 1

Assuming your language is JavaScript, you first need to parse the JSON (below I use jQuery's $.parseJSON method) and then access the appropriate property and array position. To retreive "C:\", you would do this:

var sJSON = '{"Name":["C:\/","D:\/","E:\/","F:\/","G:\/","My Documents"]}';
var oJSON = $.parseJSON(sJSON);
alert(oJSON.Name[0]); //displays C:\

If you're using JavaScript, you can use an eval() statement in place of a $.parseJSON because JSON is executable in JavaScript, but it is safer to use a $.parseJSON.

Use a JSON parsing library for your language.

In JavaScript, you can use JSON.parse. If your output is in the var output, you would do:

var obj = JSON.parse(output);
console.log(obj.path[0]);
