AutoM8 0.35 Reg Ex help?

[OneZero]

I'm trying to write a regex for host graph tree creation. Got two of them created, but can't seem to get this one to match.
Here's what I've got.
Matching on host desc, which is B100 Bink to Str0, some are B100, some are B28 or B14. So I need to match the first 3-4 chars, to a space. And I want that to be the subtree.
Tried this matching pattern, which should work I think, ^(B[0-9]*)
With replacement pattern of ${1}

But as the result, I get the whole string back B100 Bink to Str0

What am I missing?
Thanks

Hi,

Try ^(B[0-9]+) .*$
Begin with B, then one or more figure, then a space, then whatever.

Hi There,

I am using cacti 1.0.1, having issue with regular expression matching for data query output field 'ifDescr'

ifDescr showing as below,
Found item [ifDescr='V1'] index: 1 [from value]
Found item [ifDescr='V2'] index: 2 [from value]
Found item [ifDescr='V3'] index: 3 [from value]
Found item [ifDescr='V4'] index: 4 [from value]



Graph Creation Criteria

Operation - blank

Field Name - ifDescr

Matching Pattern - ^(V[1-4])
