Iterate over all attributes in a DOM node

attr-iteration.js

if (node.attributes.length) {
	// Get the known-existent list of attributes and iterate over them
	var attrs = node.attributes;
	for (var length = attrs.length, i = 0; i < length; i++) {
		// IE 5-8 (all currently shipping versions) always list all possible attributes, specified or not.
		// The "specified" member of each attribute indicates whether it was existent in the HTML and is required for the purpose here.
		// IE will also report the unique jQuery identifiers as well as jQuery's sizzle engine cache attributes, so parse those out entirely.
		if (attrs[i].specified
			&& attrs[i].nodeName.indexOf('jQuery') == -1
			&& attrs[i].nodeName.indexOf('sizcache') == -1
			&& attrs[i].nodeName.indexOf('sizset') == -1) {

			xml_array.push(' '+attrs[i].nodeName+'="'+attrs[i].nodeValue.replace(/\"/g, "&#34;")+'"');
