in reply to Tips on how to perform this regex query

I'd check CPAN first for an approximate string match module. Using the search 'edit distance' comes up with multiple candidates that look like good possibilities: Text::LevenshteinXS, Text::WagnerFischer, Text::Brew.

    Sorry roboticus, but what do you think running one of those 'edit distance' algorithms on the two strings will actually tell the OP?

    To save time, I'll tell you. Ta-dah:

    1073!

    Which means what?

    My best guess:

    <Reveal this spoiler or all in this thread>

    It doesn't tell him how different they are, nor where the best match occurs,

    Not even if the shorter actually appears in the larger to any meaningful measure of the term.
