    Default How to identify a roman numeral

    Hello All, I am having trouble identifying a roman numeral. I need to separate the txt file by chapters so i use this pattern to do it, but it does not work.

    Pattern.compile("chapter [i+x*c*l*v*][i*x+c*l*v*][i*x*c+l*v*][i*x*c*l+v*][i*x*c*l*v+]")

    any ideas?

    thanks alot
