Re^2: regex help please

-- for useless use of capturing parens, and also for backslashing < and >

I'm also thinking there's something the OP left out of the specification, because of the stipulation about "must match the first but not the second", so your solution is likely incomplete.

Good call...this might do the trick (assuming Roxy is static)

while(<DATA>) {
    chomp;
    $_ =~ s/rcvtime.*<0a>// unless /Roxy/;
    print "$_\n";;
}

__DATA__
rcvtime=2006102600322813316-sndtime=2006102600323042116-msgtext=FRM\3a
+Matd<0a> 
rcvtime=2006102611373625516-sndtime=2006102611373640716-msgtext=FRM\3a
