v7.2.3 moddle model meta-model xml xsd import export
moddle-xml
Read and write XML documents described with moddle.
Usage
Get the libray via npm
npm install --save moddle-xml
Bootstrap
Create a moddle instance
import { Moddle } from 'moddle';
import {
Reader,
Writer
} from 'moddle-xml';
const model = new Moddle([ myPackage ]);
Read XML
Use the reader to parse XML into an easily accessible object tree:
const model; // previously created
const xml =
'<my:root xmlns:props="http://mypackage">' +
'<my:car id="Car_1">' +
'<my:engine power="121" fuelConsumption="10" />' +
'</my:car>' +
'</my:root>';
const reader = new Reader(model);
const rootHandler = reader.handler('my:Root');
// when
try {
const {
rootElement: cars,
warnings
} = await reader.fromXML(xml, rootHandler);
if (warnings.length) {
console.log('import warnings', warnings);
}
console.log(cars);
// {
// $type: 'my:Root',
// cars: [
// {
// $type: 'my:Car',
// id: 'Car_1',
// engine: [
// { $type: 'my:Engine', powser: 121, fuelConsumption: 10 }
// ]
// }
// ]
// }
} catch (err) {
console.log('import error', err, err.warnings);
}
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 Writer(options);
var xml = writer.toXML(bar);
console.log(xml); // <my:root xmlns:props="http://mypackage"> ... <my:car power="10" /></my:root>
