Use .Find to get all elements that do NOT match the search properties

Hi all,   I'm trying to find a way to make my code less loopy and possibly improve the performance.  I'm trying to take a list of items, get rid of the items that I'm not interested in, and keep ...

    Hi,

     

    The below may appear to be not relevant for your real case because I don't know how color is determined, but as an idea you may consider using regular expressions for search parameters.

    Sample pseudocode:

    var objects = root.FindAllChildren(['Type', 'Color'], ['regexp: (vegetable)|(fruit)', 'regexp:^(red)'], depth);

    That is SOO exactly what I was looking for, thanks ! :smileyvery-happy:

    Syntax correction:

    It's 'regexp:[^(red)]' - it was just missing the [] around the ^(red)

    Hi,

     

    > That is SOO exactly

    Wow, great to hear! :)

    May be, needs to be checked.

    To my understanding, [red] will match if the string been processed contains either 'r', or 'e', or 'd'.

    While (red) should match 'red' exactly.

    But I might be wrong and, as I said, exact syntax needs verification.

      Not a critisism, just an update for future readers of the post :smileyhappy:

      > While (red) should match 'red' exactly

      That's the result I got when testing [red] versus (red)

        I see, thank you a lot for correction then.

        Ah, got it :)

        The corrected regexp will match a string that does not contain a token and token equals to 'red'. I.e. effectively regexp will match everything that does not contain 'red'.

        Thank you again for correction -- I'll definitely bookmark it.
