Ifml-moddle NPM

ifml-moddle

Read and write IFML diagram files in NodeJS and the browser.

ifml-moddle uses the IFML meta-model to validate the input and produce correct IFML XML.

Usage

Get the library via npm package. Consume it in NodeJS, via UMD or bundle it for the browser using your favorite module bundler.

const moddle = new IfmlModdle();

const xmlStr =
  '<?xml version="1.0" encoding="UTF-8"?>' +
  '<ifml:definitions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ifml="http://www.omg.org/spec/IFML/20140301" xmlns:ifmldi="http://www.omg.org/spec/IFML/20130218/IFML-DI" xmlns:xmi="http://www.omg.org/spec/XMI/20131001">' +
  '<ifml:iFMLModel>' +
  '<ifml:interactionFlowModel id="_myModel" />' +
  '</ifml:iFMLModel>' +
  '<ifmldi:iFMLDiagram modelElement="_myModel" />' +
  '</ifml:definitions>';


const {
  rootElement: definitions
} = await moddle.fromXML(xmlStr);

// update id attribute
definitions.set('id', 'NEW ID');

// add a root element
const ifmlViewContainer = moddle.create('ifml:ViewContainer', {
  id: 'MyContainer'
});
var modelElements = definitions.get('ifmlModel')[0].get('interactionFlowModel').get(
  'interactionFlowModelElements');
modelElements.push(ifmlViewContainer);

moddle.toXML(definitions).then(function (xml) {
  console.log(xml);
})
