JS XMLSS Builder

	// too basic atm to be worth setting up a proper repo for, but I think it has potential, assuming it isn't totally wrong
	// ... I know I could have used actual xml, but this was more amusing


	var hasOwn = Object.prototype.hasOwnProperty,
	toString = Object.prototype.toString;

	// helpers from Fortinbras library

	function ucfirst (str) {

constructor for building xml like strings

	// extracted from an earlier gist that had a more comprehensive DOM-like implementation
	// in this case, I didn't care about namespaces and I didn't require any operation but
	// append. This is too basic to be useful for most things, but good enough for what I've
	// used it for. Note that the use of ES5 accessors makes this incompatible with IE < 9.

Standalone version of XPath Module from Firebug, assumes strings have a trim method

	// AMD, Node flavored CommonJS, and old fashion global
	(function (global, factory) {
	if (typeof define === 'function' && define.amd) {
	// AMD. Register as an anonymous module.
	define([], factory);
	} else if (typeof exports === 'object') {

starting point for regexp based page search

	// this is just the starting point. you can run it in the console.
	// there are numerous problems to solve, like working out whether
	// the text it finds is visible or not -- i.e. if a node has display: none,
	// or is absolutely positioned offscreen or behind another element, or
	// has visiblity: hidden, or has height: 0 and overflow: hidden, and so on.

	function find (str, caseSensitive) {
	var head = (document.head \|\| document.getElementsByTagName('head')[0]),
	body = (document.body \|\| document.getElementsByTagName('body')[0]),
	re = RegExp(str, 'g' + (caseSensitive ? '' : 'i')),
