	function lower() {			
		return '<'+arguments[1].toLowerCase()+arguments[2] +'>';
	}	
	
	function quoteAttr() {
		attributes = arguments[2];
		attributes = attributes.replace(/(.+)=([^"].+[^"])\s+/ig, '$1="$2" '); 
		attributes = attributes.replace(/\s+(.+)=([^"].+[^"])/ig, ' $1="$2"'); 
		return '<' + arguments[1].toLowerCase() + ' ' + attributes +'>';

	if (val == undefined)
	{
		if (this.length == 0) return null;
		string = this[0].innerHTML;
		if (jQuery.browser.msie) 
		{
			string = string.replace(/<(\/?\w+)(\s*[^>]*)>/igm, lower); //fix attributes : add quotes				
			
			string = string.replace(/<(img|input)\s(.+)\B>/igm,'<$1 $2/>'); //fix tags that don't need closing tags
			string = string.replace(/<\/(img|input)>/igm,''); 
	
			//TODO : is there a way to do it without callback ?
			string = string.replace(/<(\/?\w+)\s+([^>]*)>/igm, quoteAttr); //fix attributes : add quotes
			
			string = string.replace(/<li>/igm,'</li>\n<li>'); //fix lists : first add closing /LI to all list elements
			string = string.replace(/(<ul>(\s*)<\/li>)/igm,'<ul>'); //fix lists : then remove the one folowing UL
			string = string.replace(/(<\/li>(\s*)<\/li>)/igm,'</li>'); //fix lists : then remove the one folowing UL
