How do you fetch and parse xml in node.js?

How do you fetch an xml from online with node.js and parse it into a javascript object? I’ve been searching the npm register but only found how to parse the xml-string, not how to fetch it.

Answer

To fetch an online resource, you can use http.get(). The data can be loaded into memory, or directly sent to a XML parser since some support the feature of parsing streams.

var req = http.get(url, function(res) {
  // save the data
  var xml = '';
  res.on('data', function(chunk) {
    xml += chunk;
  });

  res.on('end', function() {
    // parse xml
  });

  // or you can pipe the data to a parser
  res.pipe(dest);
});

req.on('error', function(err) {
  // debug error
});
