Don't forget streams, the more `node.js` way to parse HTML:

    var http = require('http');
    var tr = require('trumpet')();
    var request = require('request');
    request.get('http://www.echojs.com")
      .pipe(tr.createReadStream("article > span"))
      .pipe(process.stdout);

That's it! See https://github.com/substack/node-trumpet and their tests for more.
