注意：如果文本URL后面有『<』，要过滤，否则出错。

plain2link(obj.innerHTML.replace(/<br[^>]*>/gi, "\n<br />"));

将文本URL后面的『<b />』用换行过滤！

function plain2link(text){
	if(!text) return text;
 
	text = text.replace(/((https?\:\/\/|ftp\:\/\/)|(www\.))(\S+)(\w{2,4})(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/gi, function(url){
		nice = url;
		if(!url.match('^https?:\/\/')){
			url = 'http://'+url;
		}
		return '<a target="_blank" rel="nofollow" href="'+ url +'">'+ nice +'</a>';
	});
 
	return text;
}

var str = obj.innerHTML.replace(/<br[^>]*>/gi, "\n<br />");
str = str.replace(/\&lt\;/gi, "\n\&lt\;");
str = str.replace(/\&#60\;/gi, "\n\&#60\;");
obj.innerHTML = plain2link(str);
