[x3d-public] X3DJSONLD ... converts XML to JSON client side!

[John Carlson]

Also, I don’t think that converting JSON to XML is as simple as https://gist.github.com/sstur/7379870 in the general case.  So you may want to more fully constrain X3D JSON.  Please define the standard X3D JSON that is compatible with the previous link by all means.  We will gladly fall into your arms in relief.

John,

I am wondering how this might differ from the following built-in capabilities described below. What does your code do differently than these built-in methods?


XD is an (string) XML fragment, then this fragment can be inserted into the DOM (either as part of the document of a separate sub-tree) using

var parser = new DOMParser();
var xmlDom = parser.parserFromString (XD, 'application/xml');

[Ref: https://developer.mozilla.org/en-US/docs/Web/API/DOMParser]

At this point xmlDom is a DOM tree, but not inserted into the HTML document DOM.

It is possible to go back to XML string using

var S = new XMLSerializer();
var xmlString = s.serializeToString (xmlDom);

[Ref: https://developer.mozilla.org/en-US/docs/Web/API/XMLSerializer]

There is the JSON.stringify method 

[Ref: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify and https://stackoverflow.com/questions/46880822/how-to-json-stringify-a-dom-element - answer 1]

There is at least one other GItHub project (https://gist.github.com/sstur/7379870) that converts to/from JSON and strings/DOM.

Going from an internal object to JSON takes a little careful work to make sure the tree is correctly handled and the code does not follow the circular loops that are present in DOM.

The X3D JSON Loader now converts XML to JSON client-side, for your nefarious purposes!

Enjoy loading!
