Including node.js modules in the GETH attach javascript console

I'm trying to include the node.js module XMLHttpRequest, so that I can write a javascript console script to watch contract events and send out the data to a webserver.

I have installed the node.js module

npm install xmlhttprequest

And then include the module in my GETH javascript console script:

var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();

The problem is that the module is not being included:

err: Cannot find module 'xmlhttprequest'
