简单的Perl字符串匹配一个特殊的字符，即'

my $var_cot_descn="Veteran's Affairs"; 
my %cot_descn= ("Correctional","Veteran's Affairs","State Pharmacy Assistance Program","VA Medical Center","VA Mail Order Pharmacy","PHS 340B Entity"); 

if (exists $cot_descn{$var_cot_descn}){ 
    print "CustomerDomain=\"GOV\" 
     /> 
     </Org> 
     \n"; 
} 
else{ 
    print "CustomerDomain=\"COM\" 
     /> 
     </Org> 
     \n"; 
}

所有工作正常，除非我比较“退伍军人事务”导致if条件失败。简单的Perl字符串匹配一个特殊的字符，即'

我该如何解决这个问题？

你的哈希没有"Veteran's Affairs"密钥，它有一个"Veteran's Affairs"值。如果你以更常见的方式定义你的哈希：

my %cot_descn = (
    "Correctional" => "Veteran's Affairs", 
    "State Pharmacy Assistance Program" => "VA Medical Center", 
    "VA Mail Order Pharmacy" => "PHS 340B Entity" 
);

那么结构会更清晰。由于没有"Veteran's Affairs"关键，当然这个测试会送你到else分支：

if (exists $cot_descn{$var_cot_descn})

时$var_cot_descn是"Veteran's Affairs"。

也许你有你的%cot_descn倒退的第一个键/值。

不要你的意思是：

#!/usr/bin/env perl 

use strict; 
use warnings; 

# -------------------------------------- 
use Data::Dumper; 

# Make Data::Dumper pretty 
$Data::Dumper::Sortkeys = 1; 
$Data::Dumper::Indent = 1; 

# Set maximum depth for Data::Dumper, zero means unlimited 
local $Data::Dumper::Maxdepth = 0; 

# -------------------------------------- 

my @cot_descn = (
     "Correctional", 
     "Veteran's Affairs", 
     "State Pharmacy Assistance Program", 
     "VA Medical Center", 
     "VA Mail Order Pharmacy", 
     "PHS 340B Entity", 
    ); 
my %cot_descn = map { $_ => 1 } @cot_descn; 

print Dumper \%cot_descn;
