bpmn-xml-parser

BPMN XML Parser focused on message flows.

Introduction

Process models can contain multiple collaborators. In that case, the communication and handover in the process is managed with message flows. The purpose of this package to parse bpm/xml diagrams to show the resulting dependencies between the collaborators in a way that can easily be handled programmatically.

Code Samples

Import:

import XmlParser from "bpmn-xml-parser";

Initialize:

Object: new XmlParser(diagramString);

The diagramString parameter contains the full xml diagram as text/string.

Retrieve collaborationId:

String: xmlParser.getCollaborationId()

Can be useful as an identifier if you are working with multiple processes.

Retrieve id and name of participants/collaborators as object:

String[{label: name, value: id}]: xmlParser.getParticipantObjects()

Enables unaltered use in select lists like react-select.

Retrieve all names of participants/collaborators:

String[]: xmlParser.getParticipatingProcesses()

Set names of relevant participants/collaborators:

void: xmlParser.setParticipatingProcesses();

Use this if you are only interested in the dependencies of certain collaborators.

If you don't do this, all participants will be considered relevant.

Parse message flows:

JsObject: xmlParser.parseMessageFlows();

This is where the actual magic happens.

Example output:

[
  {
    "participantId": "Participant_1rmkvs0",
    "processName": "Filiale",
    "processId": "Process_1x5g5w9",
    "processVersion": "",
    "conditionalElements": [
      {
        "id": "IntermediateThrowEvent_0hrerws",
        "name": "",
        "type": "bpmn:intermediateCatchEvent",
        "triggerId": "MessageFlow_0y4pgmw",
        "triggerName": "Bestätigung",
        "originOfTrigger": [
          {
            "originProcessId": "Process_1",
            "originProcessName": "Server",
            "originProcessVersion": "2",
            "originId": "EndEvent_0214v1a",
            "originName": "Kundenkonto erfolgreich angelegt",
            "originType": "bpmn:endEvent"
          }
        ]
      }
    ]
  }
]
