Filter list by part of name

Hello everyone on the forum.
I have a basic question about filtering lists.

Above I have a list of all project link levels (3 floor, 4 floor, 5 floor…15 floor)
Below I have a list of only the numbers of the levels I want (9, 10, 11, 12, 13, 14, 15)
How do I match a list of levels, selecting only by numbers?
Like, it would be a list
9 floor
10 floor
11 floor
12 floor
13 floor
14 floor
15 floor

make the list as a string then use string contain, then use boolmask.

Thank you Vijay
Great reasoning, but how do I turn my list into a string list?
I tried by codeblock and then list.create, but when it has null, it gives an error
Know another way?

Somethin like this?

Test.dyn (16.3 KB)

If they are all based on the same sequence (Ground Floor = 0, First Floor = 1, etc) you could use a sequence and use GetItemAtIndex using your level number

Oh! Thanks!
it was perfect in the routine
thank you so much!!

Thanks for this ideia Daniel!

@_Vijay @renanemeyer This solution might not work if the elements are not in exact order!

@renanemeyer Try using nodes from archilab or designtech
