Question

I need help with this regex. I get a string like below. I want something like

ServerName: AdminServer RUNNING
ServerName: ServicesServer1 RUNNING

$rv="xxx ServerName: AdminServer  RUNNING  xxxx ServerName: ServicesServer1  RUNNING xxx"
$rv -replace ".*(ServerName: [A-Za-z0-9]*.*[RUNNING|SHUTDOWN])",'$1'
ServerName: ServicesServer1  RUNNING xxx

With what I have now I only get the last match?

EDIT:

$rv="xxx ServerName: AdminServer  RUNNING  xxxx ServerName: ServicesServer1  RUNNING 
$rv -replace ".*(ServerName: [A-Za-z0-9]*.*RUNNING|SHUTDOWN)",'$1'

gives

ServerName: ServicesServer1  RUNNING xxx

not

ServerName: AdminServer  RUNNING
ServerName: ServicesServer1  RUNNING

EDIT2:
Turns out I have over simplified this. The string looks more like this:

$rv='XXX rtification Authority - G3,OU=(c) 2008 GeoTrust Inc. - For authorized use only,O=GeoTrust Inc.,C=US". The loading of the trusted certificate list raised a certificate parsing exception PKIX: Unsupported OID in the AlgorithmIdentifier object: 1.2.840.113549.1.1.11.>
Successfully Connected to Node Manager.
ServerName: SasTTpcAdminServer

RUNNING

Successfully disconnected from Node Manager.
Connecting to Node Manager ...
Successfully Connected to Node Manager.
ServerName: XXXServicesServer1

RUNNING

Successfully disconnected from Node Manager.'

While this is not necessarily an ideal approach, it will “work” after fixing some issues:

1. [RUNNING|SHUTDOWN] is a character calss, not an aliteration. Switch it to (?:RUNNING|SHUTDOWN)

2. The .*s matches too greedily. Use .*? instead.

Final:

$rv -replace ".*?(ServerName: [A-Za-z0-9]*.*?(?:RUNNING|SHUTDOWN))", '$1'

Notice how it doesn’t match the last bit .. however, there is likely a better solution to this (note that this uses the previously discussed fixes and some tweaks of my own):

$r = [regex]::matches($rv,"(ServerName:.*?\w+.*?(?:RUNNING|SHUTDOWN))")
$r[0].Value
# -> ServerName: AdminServer  RUNNING

Then we can map the capture group values into something simpler:

$r | % { $_.Value }
# -> 
# ServerName: AdminServer  RUNNING
# ServerName: ServicesServer1  RUNNING
