parsing output of diff-lcs
===

I would like to know the difference between two strings and I'm using diff-lcs to do this.  However, I am having trouble parsing the output.

    require 'diffs-lcd'
    
        a = 'abcdef'
        b = 'abcsef'
    
    diffs = Diff::LCS.diff(a,b)

    puts diffs.inspect
    
    ==> [[#<Diff::LCS::Change:0x0000010106dcc0 @action="-", @position=3, @element="d">, #<Diff::LCS::Change:0x0000010106db30 @action="+", @position=3, @element="s">], [#<Diff::LCS::Change:0x0000010106d360 @action="-", @position=6, @element="">]]

I would like to output the character differences only, so 'd' and 's'.  Is there a way to extract the @element from that output?

Thanks
