Question

我有一个带有如下行的文件（只粘贴了两行）。这是一个巨大的文件1 GB。

6901:2014-06-30 12:24:58,584 INFO                                       BAS_Connector-thread-3 [com.orga.oslee.ra.bas.BASservice-R2.5.0.19.4] API=[BAS_SEARCH_ACCOUNTS] TID=[6c3be5be-2188-11e4-e004-6e5c369d1712] < received from Bas: [Accounts=[], MaxRecordsReached=false, ReferenceId=-9MXF14E0ST6R, IST=2014-06-30T12:24:58.578+05:30]

我想从-9MXF14E0ST6R或BAS_ReferenceId=[0:[-9MXF14E0ST6R]]

取值ReferenceId=-9MXF14E0ST6R,

my $receivedFrom =qr /^(\d{4}-\d{2}-\d{2}\s+\d{2}:\d{2}:\d{2},\d{3}).*API=\[(.*?)\].*?TID=\[(.*?)\].*?received from Bas.*?(ReferenceId=.*?,|BAS_ReferenceId=\[.*?:\[(-.*?)\]\])/;

open (IN,'<',"$file");
while (my $inputString = <IN>)
{
if ($inputString=~/$receivedFrom/)
{

my ($starttime,$api,$receivingfromtid,$ReferenceId)=$inputString=~/$receivedFrom/; 
$ReferenceId=~s/ReferenceId=//;
$ReferenceId=~s/BAS_\[0:\[//;
$ReferenceId=~s/\]//g;
print "$ReferenceId\n";
}

}

我不想做替补。

简化正则表达式。

在这种情况下，您尝试匹配两种不同的模式。因此，它们应该是两个不同的正则表达式：

use strict;
use warnings;

while (<DATA>) {
    if (/\bReferenceId=([^,]*)/) {
        print "RefID = '$1'\n";

    } elsif (/\bBAS_ReferenceId=\[ [^\[\]]* \[ ([^\[\]]*) \] \]/x) {
        print "BasID = '$1'\n";
    }
}

__DATA__

输出：

RefID = '-9MXF14E0ST6R'
BasID = '-9MXF14E0ST6R'
