for list like {"a","abc","dfe","nab",1,2,3,{1,2}}, I want to get all 
strings' position in the list which match a pattern (like 
___~~"ab"~~___). How to do it? How to use a string pattern in a list 
pattern? how to use a pattern with a condition (both list pattern&/; 
StringQ[#] and list pattern /;StringQ[]&, no working for me)

Thanks.
