Also note that if you have a tokeniser as a regexp, then once you've eliminated left-recursion from a grammar it's dead easy to write a pure perl parser for that grammar without using a parser module. See XML::XPath::Parser for an example of this, and also XML::SAX::PurePerl.

    [stevieb]: shmem thanks for the 'insight' :P
    [shmem]: good thing that Sun already took "OpenWindows", otherwise I'd not stop to shudder imagining an "OpenWindows" from MS
    [shmem]: more garbage in, more garbage out that would be
    [stevieb]: I found that win10 broke a C# library I was using for one project while enhancing tests for a Perl dist, which breaks other Perl dists, and I'm about to throw my hands up on berrybrew. win2k12 broke one thing, win10 breaks something...
    [stevieb]: ...unrelated which requires replacing a lot of code and a whole lib. I'm about to go nix only ffs
    [shmem]: stevieb: what you're doing sounds afwully complex. Too much for me this evening to provide brighter insight ;-)
    [stevieb]: I don't even own a Windows computer. Both my girl and I have a laptop each with Linux. I'm supporting Windows in some of my projects and I can't even guage whether it's worth it or not.
    [stevieb]: shmem It's something I desired to have years ago, which is why I took over berrybrew. Cross-platform build/test automation locally, or over the network Test::BrewBuild
    [shmem]: sounds good.
    [shmem]: but I'm crumbling smaller stones. remember...
