Im having trouble extracting only a matching string: OPER^ from a log4j file.
I can get this value from two different sources inside my log file:

2012-01-26 03:06:45,428 INFO  [NP_OSS] OSSBSSGWIMPL6000|**OPR20120126120537008893**|GenServiceDeactivationResponse :: processRequestGenServiceDeactivationResponse() ::

or:

2012-01-26 03:06:45,411 INFO  [NP_OSS] MESSAGE_DATA = <?xml version="1.0" encoding="UTF-8" standalone="yes"?><ns2:ServiceDeactivationResponse xmlns:ns2="urn:ngn:foo"><MessageHeader><MessageTimeStamp>20120126031123</MessageTimeStamp>**<OperatorTrxID>OPR20120126120537008893</OperatorTrxID>**</MessageHeader></ns2:ServiceDeactivationResponse>

I need to extract only the value OPR*
I’m guessing its much easier to extract it from the first one since it doesn’t involve parsing xml.

Thanks a lot in advance for your help!

    $ echo $line | grep OPR | sed -e "s/^.*OPR\([0-9]*\).*$/\1/"

    After reading your comment:

    $ echo $line | grep OPR | sed -e "s/^.*\(OPR[0-9]*\).*$/\1/" | head -1
