Now that DOM4 includes DOMString as an argument type for Node methods, I'd like
to have a clear and easy path to serialize a JSON object into an XML DOMString.
It's not a trivial task. Any takers?
Example:
JSON.toXML({div:'Hello world'});
I'm curious why you would want such a thing. You can store DOM trees
as strings and revive them when used. You can transmit DOM across XHR
either as a string or, soon, directly as a document.
I don't see a reason to store DOM into an alternative JSON structure.
JSON is widely more popular than XML for a lot of APIs. People use
JSON.stringify an parse quite a bit. I may be misunderstanding what it is you
mean by DOM.
The first paragraph of your original email talked about the Node
methods now accepting DOMStrings. Since you then asked for a way to
convert JSON to a DOMString, I reasonably assumed the two statements
were related.
I guess I should be more direct, then. What problem are you
attempting to solve with this feature?
I'd like to skip the population of a DOM via: for(var i in obj) {
dom.appendChild(i);.... };
Anne has "overloaded Node.appendChild" with DOMString.
That makes appendChild('<div>hello world</div'); easier. That's my
understanding, anyway.
I'm trying to solve the appendChild({div: 'hello world'}); syntax that
we were trying to address with Element.create.
I know that a JSON.toNode with XSL or other selectors could be a nice
way of doing things in the future, similar to Microsoft's LINQ (but
different).
JSON is widely used, it's quite useful, and it'd be nice to have better
integration between JSON and DOM+XML.
Using JS objects as a means of populating has been discussed repeatedly
for use with SVG.
Having looked at this again, I'd really prefer to have something like
Node JSON.toNode(obj) over DOMString JSON.toXML(obj).
