Read and write BPMN 2.0 diagram files in NodeJS and the browser.
__bpmn-moddle__ uses the [BPMN 2.0 meta-model](http://www.omg.org/spec/BPMN/2.0/) to validate the input and produce correct BPMN 2.0 XML. The library is built on top of [moddle](https://github.com/bpmn-io/moddle) and [moddle-xml](https://github.com/bpmn-io/moddle-xml).
Get the library via [npm package](https://www.npmjs.org/package/bpmn-moddle). Bundle it for the web using [browserify](http://browserify.org) or [webpack](https://webpack.github.io).
```javascript
var BpmnModdle = require('bpmn-moddle');
var moddle = new BpmnModdle();
var xmlStr =
'<?xml version="1.0" encoding="UTF-8"?>' +
'<bpmn2:definitions xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL" id="empty-definitions" targetNamespace="http://bpmn.io/schema/bpmn">' +
'</bpmn2:definitions>';
moddle.fromXML(xmlStr, function(err, definitions) {
// update id attribute
definitions.set('id', 'NEW ID');
// add a root element
var bpmnProcess = moddle.create('bpmn:Process', { id: 'MyProcess_1' });
definitions.get('rootElements').push(bpmnProcess);
moddle.toXML(definitions, function(err, xmlStrUpdated) {
// xmlStrUpdated contains new id and the added process
});
});

You need [grunt](http://gruntjs.com) to build the project.
To run the test suite that includes XSD schema validation you must have a Java JDK installed and properly exposed through the `JAVA_HOME` variable.
Execute the test via

grunt test
```
Perform a complete build of the application via
```
