If you want to use regex you can do it. My suggestion is to use a three step approach. Split the text into lines, catch the text you want, and join the strings again:

var text = ".hovered,.showFrame .container-fluid .added-element:hover , #MR_Modal_View.showFrame .container-fluid .added-element:hover ,.showFrame .container-fluid:hover,#MR_Modal_View.showFrame .container-fluid:hover,.added-element:hover, body ,div.test , #MR_Modal_View_Modal .added-element:hover, .ui-resizable-resizing";
text = text.replace(/,/g,'\n').replace(/.*:hover\s*\n*/g, "").replace(/\n/g,',');
