Extracting a specific item from a list

How do i go about extracting the curves from this list? Cant seem to figure it out, I want to create a new list with just the curves, not the arc-like curves just the curves. Any help is appreciated. Thank you

You could try something along these lines:

Anything you want to keep give a 1 and anything to cull a 0. Note that the string must be exact as it is case sensitive. Higher Res image:Replace.png

Hello Danny, thanks for your share.

maybe, if you have a geometrie param in entry:

Referenced "", do you have a syntax

Thanks for all

Is this a question about the error? If so then it has to be converted to a string for the replace function to work. Use the output of the text panel.

EDIT also you are going to get an issue with data matching the way you have it. To be sure you get all the correct replacements you will have to pass it through 3 separate Fx components.

Thank you for answer,
by repeating your same definition I produce an error.

I think its due to the data matching curve is being applied to the first referenced item, point to the next and line-like to the remainder.

If you want to do it with just one fx component then you need to graft the F input to get three separate lists and then manipulate the results into one. I have used the Flip Matrix and Sort component to achieve this. The Sort will ignore any strings and give you just the numbers.
