regular expression for sparse matching ?

[Klaus Wais]

I try to parse and modify the NetConfig file with regsub.

I would like to change the IP setting of a thread.

The idea is to find the thread name in the NetConfig and then look for the first occurance of LOCAL_IP, etc. etc.

The first pattern I tried was {.*protocol HL7_tcpip.*? LOCAL_IP} but the sparse matching seems not to work.

(In the NetConfig there is a blank before LOCAL_IP)

I found out that {.*protocol HL7_tcpip.*?LOCAL_IP} is doing the job.

Any comments about the different behaviour of the 2 patterns ?
