- * JsonPath is to JSON what XPATH is to XML, a simple way to extract parts of a given document. JsonPath is

- * <p/>
- * JsonPath allows you to compile a json path string to use it many times or to compile and apply in one
- * single on demand operation.
- * <p/>
- * Given the Json document:
- * <p/>
- * <pre>
- * String json =
- * "{
- * "store":

- * [
- * {
- * "category": "reference",

- * "category": "fiction",
- * "author": "Evelyn Waugh",
- * "title": "Sword of Honour",
- * "price": 12.99
- * }
- * ],
- * "bicycle":
- * {
- * "color": "red",
- * "price": 19.95
- * }
- * }
- * }";
- * </pre>
- * <p/>
- * A JsonPath can be compiled and used as shown:
- * <p/>
- * <code>
- * JsonPath path = JsonPath.compile("$.store.book[1]");
- * <br/>
- * List&lt;Object&gt; books = path.read(json);
- * </code>
- * </p>
- * Or:
- * <p/>
- * <code>
- * List&lt;Object&gt; authors = JsonPath.read(json, "$.store.book[*].author")
- * </code>
- * <p/>
- * If the json path returns a single value (is definite):
- * </p>

-     * determine the boundaries.  Since the Path parser isn't aware of JSON processing this uber routine is needed.
