Filter Family names by PART of string

[Magdalena_Nikolas]

HI, I’m new to Rhino and Dynamo for Revit. I would like to filter families by part of its name. The name doesn’t have spaces so I need to pick up part of string. Unfortunately option I found so far string.contain filter only string separated by spaces. I truly believe there is method of writing or function that allow me to search only for part of string. Please advice. Many Thanks.

Hi Magdalena,

A number of ways to do this.

There are string filtering characters available in querying types.

You can use a regex as well, which is extremely flexible.

Parameter Rule filtering works as well
