NEW: XML to JSON Plugin

Rate this Message:
I wrote this a few months but didn't have the time to share it. Now that I've re-done the documentation for 2 of my plugins I thought I'd give it a few hours, knock some examples together and share it with the whole world (ok, maybe just a few people). Basic example: var xml = '<xml><message>Hello world</message></xml>'; var json = $.xml2json(xml); alert(json.message); // shows "Hello world" Ajax example: var file = 'data/hello.xml'; //<xml><message>Hello world</message></ xml> $.get(file, function(xml){ var json = $.xml2json(xml); alert(json.message); }); See the documentation page for more examples and demos. XML to JSON Plugin - http://fyneworks.com/jquery/xml-to-json/ As always, feedback is welcome! Cheers, Diego |

Hi Alexsandro, Do you mean.... (1)"convert the generate JSON back to XML"? OR... (2)"define a javascript object and convert it to XML"? If (1): I initially built this plugin for my personal use (for my "convenience") so I could easily process XML data. Because of that, I didn't bother to differentiate between attributes / nodes. ie.: <xml><person><name>Diego</name></person></xml> ...gives the same output as this... <xml><person name="Diego"></person></xml> ...so it would be impossible to "reverse the conversion". If (2): This is quite easy. And actually, it would be pretty similar to the code I wrote to show the JSON structure in HTML (Under Examples > Basic/Extended Structure) I will write this when I get a chance, but I'd rather wait for the feedback on this plugin to work out the best way to do it...

Hi Chris, I hadn't seen xotree before, but I found it... http://www.kawa.net/works/js/xml/objtree-e.html ...and looking at the examples, it seems to behave exactly like my plugin but it's more flexible with options and built-in ajax support. It's definitelly a good base for future development of my plugin... Cheers, Diego A. On Jul 7, 8:10 pm, "chris thatcher" <thatcher.christop...@...> wrote: > Have you looked at xotree.js ?

yeah it would be great to see it ported to a jQuery plugin in combination with your work and then you could actually use jQuery ajax and it would be cleaner. I've used it a lot and for me the big thing is the ability to easy set what elements are treated as array's even if only one is present (because it keeps the code using it simpler, less cases), and specifying the attribute prefix (I use '@') because I can basically use e4x like syntax.
I also made a modification to xotree locally to allow a flat serialization/deserialization so that the item becomes a list of name/value objects, the name being the 'javascript path' eg 'foo.bar[0].@goop' and the value is the simple value. This was extremely useful for fast development with GoogleGears because I could have a generic table for all objects and use the powerful 'name LIKE' queries to find objects stored in the db. I'd love to help you develop this or give feedback because it would also help promote some mvc stuff I'm build for the jQ community.

Hi Chris, I'd be glad to work on this with you. Unfortunately, I'm completely tied up with a couple of other projects for the next few days. I won't have a chance to work on the next version, but I'll let I know as soon as I make some changes. AJAX: Although I released this as a jQuery plugin, it doesn't actually make any use of jQuery functionality, other than the $.each function. But as you suggested, it does make sense to integrate it with jQuery a bit further and to include ajax. FORMAT: As far as formatting is concerned, I understand that you'd like the output to follow a certain format, but is this really something that is worth working on? Isn't what I've got at the moment enough, ie.: use arrays only when necessary OR always use arrays. Is there really a need to specify which nodes should be arrays and which shouldn't? Serialization/De-serialization: I like the idea (like the firefox about:config page), but what affect would this have on memory? ie.: by doing this, wouldn't we essentially double memory usage by storing every value in data['a.b.c'] as well as data.a.b.c? Again, thank you for your interest in this project. I look forward to your reply... Cheers, Diego A.

Same boat here so we can organize a little then push forward.
Yeah actually I think it's normally sufficient to let the user use jquery ajax as usual but just provide easy functions to unmarshal/marshal into the format they need where ever they need it. It reduces the size of the plugin and I've sort of found most ajax-convenience functions in plugins aren't exactly what I need so I end up not using them anyway. Not always true though and if you think there some benefit I really don't feel very strongly either way (just playing devils advocate.)
Where it really became an issue in a production environment was that I always had to test every 'element' to see if i needed to treat it as an array or object. And every time I started to rely on it being an {} or [], there was some corner case that came up gave me the other and the code broke. This is especially true in templates.
They are actually different objects so you'ld have myJsonObject.a.b.c and myRejosnObject['a.b.c']. Normally how I use it is I only use json form in code, but marshal to/from the rejson when serializing to/from sqlite, and marshal to/from the xml form when serializing to/from the server. But this was just my use case. In general the idea is that only one form is present in memory at a time, but it's easy to move between them when I need to. So if I wanted to provide a nice table to edit an object, I could retreive that object as rejson from the db and I'd just leave it in the same form or if it came as xml from the server I'd marshal directly to rejson, skip json, and delete the xml footprint. In the end I think the marshalling performance is what we focus on and let the user decide when they need delete objects. Just some thoughts. I'll try to clean up some older example code. I also think it might be worth thinking about how Ariels jquery.collections and something like jspath could be used to provide some more jquery-like, e4x-ish approach so we could have var data = jqE4X(xml);//basically marshals to json jqE4X('a..c', data).each(function(){ //etc gives us an array of all decendants 'c' of data.a }); Or is this not at all what you have in mind?

Hi Chris, AJAX: $.get(url2xml, function(response){ var json = $.xml2json(response); // do stuff }); Having said that, it would be very easy to assume that an ajax call is required when a function is sent in one of the parameters, for example: $.xml2json(url2xml, function(json){ // do stuff }); ... which doesn't really save (or cost) much time (or code) but it provides a simple little hook for Ajax calls. :-D FORMAT: OK, my current implementation allows you to choose between 2 formats: simple - arrays when necessary extended - always use arrays ...isn't that enough to solve the problem of not knowing what to expect? In your case for example, just use extended mode and you're good to go. I just can't see a scenario where the user of this plubing would insist of choosing specific formatting options for different 'branches'... Am I being un-reasonble? Serialization/De-serialization: I see what you're saying and it seems great. I'd have to figure out how to make this work, but I have had an idea which might just do the job. In the documentation, I wrote a script that goes through the json object and represents it in HTML. That same script could be used to create a 'map' of the json structure. This map could be an array OR maybe even better, a simple string with the path ("reference") to every node in the structure. Something like this: Consider this XML: <house> <kitchen> <dishwasher>RED</dishwasher> <fridge>WHITE</fridge> <telly>24 INCH</telly> </kitchen> <lounge> <sofa>BROWN</sofa> <telly>50 INCH</telly> </lounge> </house> Which would result in the following map... JSON MAP: [ "kitchen", "kitchen.dishwasher", "kitchen.fridge", "kitchen.telly", "lounge", "lounge.sofa", "lounge.telly" ] That way we could come up with some xpath-like markup to search through nodes just like you suggested... json.find('dishwasher') // gives us array with nodes kitchen.dishwasher json.find('dvd') // gives us an empty array json.find('telly') // gives us array with nodes kitchen.telly and lounge.telly. $.each(json.find('telly'), function(i, node){ // 1st - kitchen.telly node // 2nd - lounge.telly node }); How does that sound???
