| Title  : Go Port of Stefan Goessner's JSONPath – XPath for JSON
;
JSON Path is a tool for extracting data out of JSON documents.
»

§ What is JSONPath?

JSONPath is XPath for JSON documents. To find out more checkout [[ Stefan Goessner's JSONPath site ][ http://goessner.net/articles/JsonPath/ ]].

This tool does not aim to fully support the specification. Just the parts I need
to implement the JSONGrep tool.

§§ JSONPath expressions

JSONPath expressions always start with a root element which is represented by the [* $ *].

JSONPath expressions can be represented using the [** dot **]–notation 

«code;
$.store.book[0].title
»

or the [** bracket **]–notation

«code;
$['store']['book'][0]['title']
»

for input pathes. Internal or output pathes will always be converted to the more general
[** bracket **]-notation.

«comment;
The spec, also, support * for member names and array indices, as well as '..' and
and array slice syntax of [start🔚step] but for now; we are not going to support
them. If I end up adding support we will have to modify this.
