Subject: Re: Regex to divide document into sections?

Hi,

   This is as best as I can go (with a limitation from Ruby's Regexp
LookBehind).  It does not allow me to do variable numbers of digits;
therefore the following will work as long your digits are all single;
else, if you have w=23, then kaput...

#/usr/bin/ruby

string =<<END
This is an example.
        a = 1
    Of what I mean.
        b = 2

    And it can go on
    like this.

        c = 3
    For ever and ever.

        d = 4

    So how does one parse it?
END

temp_array = string.split(/(?<=[a-z] \= \d)[\r\n]/)

temp_array.each { |item| put item}
