Especially when some xrefed layer contain certain string also.
Set up a layer filter contains:
[~AB]*string*
string*
A,B refer to the first letter in your xref layers.
For example, you have some xref layers named:
6532-Interior-01|rd-floor-01
Nd-Interior-01|rd-floor-01
...
and current drawing layers named:
a-floor-b1
floor-01
Just create a layer filter
[~6N]*floor*
floor*
As the result, the layer filter only display layer a-floor-b1.
It does work when there is another layer named "N-floor" in current drawing because it filters it out.
You need create more lines to specify these layers which start with the excluded letters.
