Is there a way to find a substring containing wildcards?

Hi All

I am looking for a way to search a known string for a known substring. I can set this up easily enough using the find substring node and it gives me back the index.
My problem is that I want to search a string for a substring where I dont care what position X is.

For example;

Full String: “Hello UE4 Answers”

Substring: “UE@” - where @ is a single character wildcard.

I have taken a look through the Wiki & Documentation and have found the ‘matches wildcard’ but I cant work out what this does or even if it helps. Has anyone else run into a similar task?

Cheers;

I ran exactly into the same trouble. For now I use a combination of find,get and start with substring…

Was just trying this - trick is to wrap the wildcard string so that it matches all the characters before and after the substring you’re looking for. (Note: “*” matches any number of characters including none. “?” matches any single character)

So, if using the blueprint function MatchesWildcard:

SourceString: “MOUNTA_0000_F_N0000_R1001_BASE_001”

The Wildcard pattern “R?001” fails, but “*R?001*” succeeds.

In your example.

SourceString: “Hello UE4 Answers”

You’d use the Wildcard pattern “*UE?*”
