Thank you both for the suggestions. From the examples at your listed URL the Contains node appears only useful for exact matches, not pattern matching. Pattern matching is what I need. It could be my lack of UBot Dev knowledge.. Notepad++ has a great RE capability and is open source (no nags or evaluation copies..). Give it a try if you haven't used it before. Manipulating the data file outside of UBot is not the challenge rather having UBot do the processing is my challenge. Thanks again for your advice.

Sorry to revive an old thread, but this is the closest solution and others could likely benefit from this knowledge.. How does one discard lines when reading lines from a CSV file and creating a list that begin with a given comment character? ; or # ? The CSV will contain comments for readability, I do not want my list to. Something like if #line matches /^[^#;].*/, keep #line Thanks
