Regular Expression Assistance

[g_speran]

Wondering if someone can put eyes on this and tell me what i am doing incorrectly. I've tried several option but make it worse

Hoping someone can quickly spot my error.

i need to get rid of the doublequotes after 'value=' and before '/>'

Thanks in advance

my $content = '<entry key="maxcompdatastripe" value="41943040" />';
my $maxreplacement_value = ' "20917520" merge="keep" ';
$content =~ s/(<entry key="maxcompdatastripe" value=")[^"]*("\s*\/>)/$
+1$maxreplacement_value$2/g;
print "Content: $content\n";

Expected results: 
<entry key="maxcompdatastripe" value="20917520" merge="keep" />

Actual Results:
Content: <entry key="maxcompdatastripe" value=" "20917520" merge="keep
+" " />

XML is better handled by an XML-aware tool.

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

use XML::LibXML;

my $content = '<entry key="maxcompdatastripe" value="41943040" />';

my $entry = 'XML::LibXML'->load_xml(string => $content)->documentEleme
+nt;
$entry->{value} = '20917520';
$entry->{merge} = 'keep';
say $entry;

Why a regex *really* isn't good enough for HTML and XML, even for "simple" tasks

I have figured this out

$content =~ s/(<entry key="maxcompdatastripe" value)="([^"]*)"\s*\/>/$
+1=$maxreplacement_value\/>/;
