I just got Ubot and my first bot is becoming huge. I have a problem when my regular expressions do not find the target on a page, the bot throws an error. I would like to silently continue the script as usual. For example I scrape URLs in a catalog, but not all catalog entries have URLs. So maybe 50% of the time it is a fail by the bot and it stops. But I still want the non-URL catalog entries to be saved and continue to next entry. How do I avoid this?
