feedr/source/plugins/xml.js

Use feedr to fetch the data from a remote url, respect its caching, and parse its data. Despite its name, it's not just for feed data but also for all data that you can feed into it (including binary data).

'use strict'

module.exports.parse = function parseXML(
	{ feedr, feed, response, data },
	next

	// Detect
	const isXML =

		['.xml', '.atom', '.rss', '.rdf', '.html', '.html'].indexOf(
			feed.extension

		response.headers['content-type'].indexOf('xml') !== -1 ||
		response.headers['content-type'].indexOf('html') !== -1
	if (!isXML) {
		next()
		return
	}

	// XML options
	const xml2jsOptions = require('extendr').deep(

	// Prepare Parse
	const xml2js = require('xml2js')
	const parser = new xml2js.Parser(xml2jsOptions)
	parser.on('end', function(data) {
		next(null, data)

	// Parse
	try {

	} catch (err) {
