regex to select text between 2 string? -

month: march 2011 month: jan 2012 month: dec 2011

and i'd write regex select name of month (ie "march") 2011. mean select between string "month: " , year "2011". regex made

^(month:)[a-za-z0-9]+(2011)$

but doesn't seem work. what's wrong??? results should "march" , "december". thanks!

use lookahead:

/[a-z]+(?= 2011)/ig
