Want to parse a OGC GetCapabilities Document to JSON with nodejs?. This will bring filesize down to 10%!

gistfile1.js

var allOGC = function(req, res) {
  if (req.query) {
    //set method from req
    console.log(req.method);
    var options = {
      method: req.method,
      url: req.query.q,
      headers: {
        'User-Agent': 'opendispatcher'
      },
      timeout: 6000 //6 seconds
    };
    var request = require('request');
    x = request(options);
    x.on('response', function(response) {
      var data = [];
      response.on('data', function(chunk) {
        data.push(chunk);
      });
      response.on('end', function() {
        var finaldata = data.join('');
        var xml2js = require('xml2js');
        var parser = new xml2js.Parser({explicitArray: false, mergeAttrs: true, stripPrefix: true});
        parser.parseString(finaldata, function(err, result) {
          if (err) {
            console.log(err);
            res.end();
          } else {
            res.json(result);
          }
        });
      });
    });
    x.on('error', function(err) {
      res.status(400).json({
        "error": "Timeout on proxy"
      });
    });
  } else {
    res.status(400).json({

router.route('/ogc/').all(allOGC);
