@eclipse-daanse/emf-xml

Reads and writes XML for any Ecore model, driven by ExtendedMetaData. Knows nothing about XMLA.

Part of an XMLA client in TypeScript, built on @emfts/core, the TypeScript implementation of Eclipse EMF. The Ecore models are the only description of the protocol: reading and writing run over ExtendedMetaData and reflection rather than hand-written XML per rowset.

Install

npm install @eclipse-daanse/emf-xml@next

What it does

Reads and writes XML for any Ecore model. The mapping comes from ExtendedMetaData on the model, so there is no generated or hand-written reader per type — a model that carries the annotations can be read and written as it is.

import { EcoreXmlReader, EcoreXmlWriter, XmlCursor, XmlWriter } from '@eclipse-daanse/emf-xml';

const root = new EcoreXmlReader().read(XmlCursor.parse(xml), someEClass);

const out = new XmlWriter();
new EcoreXmlWriter(namespaceUri).write(out, root, 'root');

XmlCursor is the pull parser underneath, usable on its own when a document should be walked rather than materialised. Unknown marks what the model did not describe, so an unexpected element is visible instead of dropped.

This package knows nothing about XMLA.
