moddle-xml

moddle-xml

XML import/export for documents described with moddle.

Usage

Get the libray via npm

npm install --save moddle-xml

Bootstrap

Instantiate a moddle instance

var Moddle = require('moddle'),
    ModdleXML = require('moddle-xml');

var model = new Moddle([ myPackage ]);

Read XML

Use the reader to parse XML into an object tree that represents your model descriptor:

var model; // previously created

var xml =
  '<my:root xmlns:props="http://mypackage">' +
    '<my:car id="Car_1">' +
      '<my:engine power="121" fuelConsumption="10" />' +
    '</my:car>
  '</my:root>';

var reader = new Reader(model);
var rootHandler = reader.handler('my:Root');

// when
reader.fromXML(xml, rootHandler, function(err, cars, context) {

  if (err) {
    console.log('import error', err);
  } else {

    if (context.warnings.length) {
      console.log('import warnings', context.warnings);
    }

    console.log(cars);

    // {
    //  $type: 'my:Root',
    //  cars: [
    //    {
    //      $type: 'my:Car',
    //      id: 'Car_1',
    //      engine: [
    //        { $type: 'my:Engine', powser: 121, fuelConsumption: 10 }
    //      ]
    //    }
    //  ]
    // }
  }
});

Write XML

Use the writer to serialize the object tree back to XML:

var model; // previously created

var cars = model.create('my:Root');
cars.get('cars').push(model.create('my:Car', { power: 10 }));

var options = { format: false, preamble: false };
var writer = new ModdleXML.Writer(options);

var xml = writer.toXML(bar);

console.log(xml); // <my:root xmlns:props="http://mypackage"> ... <my:car power="10" /></my:root>
