<html> <head> <title>…</title> <script type="text/javascript" src="jsonpath.js"></script> </head>
The jsonPath function takes a JSON object (not as a string, but as a JavaScript object) and applies the path operation to the contents, returning either the matched values or a normalized path. Let's see an example.
How to do it…

var o = { /* object from the introduction */ };
var result = jsonPath(o, ...
