字符串替换问题

sclego

RFC1213-MIB::atPhysAddress.3.1.202.201.2.18 = Hex-STRING: 00 0D ED 9B 78 BF

请问行如这样的字符串,我只想取最后的00 0D ED 9B 78 BF  该怎样做匹配呢?
能否写出语法,多谢

sclego

RFC1213-MIB::atPhysAddress.2.1.202.201.2.41 = Hex-STRING: 00 0D ED 9B 81 3F
RFC1213-MIB::atPhysAddress.2.1.202.201.2.42 = Hex-STRING: 00 0C 86 24 E4 00
RFC1213-MIB::atPhysAddress.3.1.202.201.2.17 = Hex-STRING: 00 0D ED 9B 81 3F
RFC1213-MIB::atPhysAddress.3.1.202.201.2.18 = Hex-STRING: 00 0D ED 9B 78 BF

我的意思是中间在变化,因此我需要根据两头的条件,截取我需要的最后部分的字节00 0D ED 9B 78 BF
我该怎样做呢?

1. $s = 'RFC1213-MIB::atPhysAddress.3.1.202.201.2.18 = Hex-STRING: 00 0D ED 9B 78 BF';
   
2. ($x) = $s =~ /: (.*)$/;

高手啊,我成功了，多谢

sclego

$s = 'RFC1213-MIB::atPhysAddress.3.1.202.201.2.18 = Hex-STRING: 00 0D ED 9B 78 BF';
($x) = $s =~ /: (.*)$/;
老大,革命又出新问题了,   我想截取,最后只剩下这种对应关系,
RFC1213-MIB::atPhysAddress.2.1.202.201.2.41 = Hex-STRING: 00 0D ED 9B 81 3F
RFC1213-MIB::atPhysAddress.2.1.202.201.2.42 = Hex-STRING: 00 0C 86 24 E4 00
RFC1213-MIB::atPhysAddress.3.1.202.201.2.17 = Hex-STRING: 00 0D ED 9B 81 3F
RFC1213-MIB::atPhysAddress.3.1.202.201.2.18 = Hex-STRING: 00 0D ED 9B 78 BF

202.201.2.41      00 0d ed 9b 81 3f
202.201.2.42      00 0c 86 24 e4 00
202.201.2.17      00 0d ed 9b 81 3f
我该怎么做啊

给你个比较笨的解决参考……

my ($x,$y) = $temp =~ /.+s\.\d+\.\d+\.(.*) =.+: (.*)$/;
print "$x\t$y\n";
