Parse xml to json in mobile

Anyone have any pointers on how this can be achieved?

I've tried to use Thomas Frank's xml2json.js converter (http://www.thomasfrank.se/xml_to_json.html) however this throws up an error when I try to include it.

  • I have created a commonJS module, built for Appcelerator that does this and a bit more in the same style as Thomas Frank's. It is github.

    So you can do this:

    var XMLTools = require("XMLTools").XMLTools;
    var my_json = new XMLTools(your_xml_string).toJSON();

    • I'm attempting to use your js module from github, but getting one error:

      "can't find variable: exports"

      I see that commented at the top of your source code, but don't see how to fix it.

    • XMLTools.js is a CommonJS module. You need to use the require statement to import it. Have a look at the app.js example on github.

      The comment at the top /*globals exports*/ is just so JSLint doesn't complain.

  • Is the error you're getting a 260 error? If so, double check your path to the .js file, 260 means whatever you're trying to refer to can't be found.

    Maybe you can have a PHP somewhere that handles getting the data and doing the conversion for you? Might make your app run faster too if you offload that work to something faster.

  • The error I'm getting is:

    [ERROR] Script Error = * -[NSCFString appendString:]: nil argument at win1.js (line 1).

    The file is in same directory the calling script.
    I'm using the following line to attempt the include:

  • Did you ever get a resolution for this? How did you end up handling your XML to JSON conversion?

  • I have tested the moduel with a gpx (xml) file. The code gives me a empty string.

    var xml = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, "routen/" + _e.item.url + ".gpx").read().text;
    var XMLTools = require("/modules/xmltools").XMLTools;
    var parser = new XMLTools(xml);
    var route = parser.toObject();

    • Noticed simular issue due to blank text nodes. Updated XMLTools.traverseTree to skip over blank child nodes of text type instead of returning the blank value. You can view the changes here:

  • Here is a running code which read all XML in a directory and convert to JSON:

    exports.getlist = function(_qti, _callback) {
        var qtidir = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, _qti);
        if (qtidir.exists() === false)
        var dir_files = qtidir.getDirectoryListing();
        for (var i = 0; i < dir_files.length; i++) {
            if (!dir_files[i].match(/\.xml$/i))
            var XMLTools = require('modules/XMLTools');
            var parser = new XMLTools(Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, _qti, dir_files[i]).read().text);
