Thank you - I have considered using Algorithm::Diff before, as Text::Diff seems to be based on that and one could, as you describe, create even more granular deltas than just line by line comparisons. The latter would however be fully sufficient for my needs, but I think I'll give Algorithm::Diff a closer look now :)

Kind regards
