Jsonpath Or Other Xpath Like Utility For Json/javascript; Or Jquery Json

I have been looking at JSONPath and though it seems pretty well done, I wonder if anyone has worked with it and can comment on its usability, or can recommend alternatives? What w

Solution 1:

Check out JSON Select - CSS-like selectors for JSON.

Solution 2:

Definitely would be a useful utility.

My opinion is that the best way to approach this would be to stay as similar as possible to css selectors, as you indicate. I'd recommend looking under the hood at jquery's implementation of selectors.

I would suggest something like

var banana = object.function(jsonObect, "holding #Banana");
var leftHands = object.function(jsonObject, "appendage[type=hand][side=left]");

instead of your usage examples.

I'm not sure how the upcoming native json support will affect this...

Solution 3:

OK, I have created a prototype for this, available here: http://code.google.com/p/jfunk/

It has already proven useful for me, so I will probably slowly improve and refactor it into something nice. But if I get good feedback, I can move more quickly. I would also welcome help.

Solution 4:

Try to using JSPath -- https://github.com/dfilatov/jspath.

JSPath is a domain-specific language (DSL) that enables you to navigate and find data within your JSON documents. Using JSPath, you can select items of JSON in order to retrieve the data they contain.

JSPath for JSON like an XPath for XML.

Solution 5:

Dojo's dojo.getObject has a facility that works loosely like this, where you can provide a path like "a.b.c" to the property you want to fetch.

Check it out:

http://api.dojotoolkit.org/jsdoc/1.3/dojo.getObject

I don't think it understands arrays quite that well and I think it is missing a full-featured selector language like the one you are suggesting.

As for usage, I've coded a selector language like the one you are suggesting, but for a client, and array addressing is very proprietary to their particular object structure.

I would definitely use a system like this if you were to make it, and perhaps even contribute if I saw an area I could help with.
