ELAN Parser

A simple parsing library for the ELAN NRW XML files. Consumed by the Fruchtfolge model.

Installation

npm install elan-parser

Usage

Standalone usage

const parser = require('elan-parser')
const { readFileSync } = require('fs')
 
try {
  const xml = readFileSync('path/to/xml')
  const gml = readFileSync('path/to/gml')
  const data = elan.join(elan.parseXML(xml), elan.parseGML(gml))
  
  // do something with the data (e.g. store in Database)
} catch (e) {
  throw new Error(e)
} 

In combination with the elan-api

const elanGet = require('elan-api');
const parser = require('elan-parser')
 
async function getLatestInvekosData(farmNo, pass) {
  const xml = await elanGet(farmNo, pass)
  const gml = await elanGet(farmNo, pass, {type: 'Geometrien'})
  
    return parser.join(parser.parseXML(xml), parser.parseGML(gml))
}

Testing

Place your testing XML files in the test/data directory. Upon first run, uncomment the following line in test/test.js

fs.writeFileSync(`test/results/${fileName}.json`,JSON.stringify(data))

and comment out the following lines. Inspect the resulting .json files for correctness, then revert test/test.js to its original state. Once the setup has been completed, you can npm test as always.
