So I am trying to delete prims by name and attribute at once.
Im trying to do this on the filter by expression but for god knows what I cannot seem to find the right format to type it.
@name==“base_name_*” && @att==1
does not produce anything.
The problem seems to be in the string attribute
as
@att==1
gives me the appropriate result.

I tryied searching for the answer to this but everyone uses the group function, my self included. But now I find myself needing to filter by expression.
Am I missing something here? shouldn't
@name==“base_name_*”
work?

the group syntax is described here:
http://sidefx.com/docs/houdini/model/groups.html#manual [sidefx.com]
so to do what you want you simply do


which would work in the group fields of the nodes
unless of course you are talking about Group Expression node which uses VEX then it would be:

tamte
match(“base_name_*”, s@name) && @att==1

thanks that is exactly what I was searching for…Basically I knew how to do it in the group syntax but I was confused about how to do it in the filter by expression.

Nico.

the syntax of ^!@att=1 to me is downright ludicrous…

If I want to test if something is X, I would test it in the positive…ie…are you X ?

It's silly to ask in the double negative like ‘Are you except not X’ ?

Not having a go at you, of course, but just commenting on the syntax ^!…..no it ain't ‘simple’…it's ridiculous
