[Boost-users] regexp - how to do an anti-match on a word

Boosters:

 

I'm having trouble determining a regular expression that will do the
following:

 

1.      Match the following strings:
TermGeMstreamIPTriplePlay_11.0.IpTxMstream_0.DefaultGateway
TermGeMstreamIPTriplePlay_11.0.VplsTxMstream_0.CurMbps
TermGeMstreamIPTriplePlay_11.0.MplsTxMstream_0.AvgMbps
TermGeMstreamIPTriplePlay_11.0.MacTxMstream_0.Address

 

2.      But not match the string:
TermGeMstreamIPTriplePlay_11.0.TrafficTxMstream_0.RampStart

 

So, essentially match the strings with IpTx, VplsTx, MplsTx and MacTx,
but not match strings with TrafficTx.

 

Right now, I have: 

 

.*\.(IpTx|MacTx|MplsTx|VplsTx)Mstream_0\..*

 

This works, however, it is not very robust because there may be more
entries added to the matching words over time.

 

Is there someway to do an anti-match on the word "TrafficTx"? Something
like:

 

.*\.(!TrafficTx)Mstream_0\..*

 

Thanks,

 

David
