hacked way to get a string inside two

gistfile1.cs

var _text = "this text happens before<paypal>aaa</paypal>this text happens after";

Func<string, string,string, string> subString_InBetween = 
	(text, before, after) 
		=>{
			 var splittedText =  text.subString_After(before).split(after) ;
			 if (splittedText.size() ==2)
			 	return splittedText.first(); 
			 return "";
		  };

return subString_InBetween(_text, "<paypal>","</paypal>");
