Get all occurances of matches pattern perl - regex

Question

if we are in the following case:
my $str = <<EO_STR;
Name=Value1 Adress=Value4
Name=Value2 Adress=Value5
Name=Value3 Adress=Value6
EO_STR
I have a table "T1" in the database with columns: ("Name", "Address") and I want to put on the column "Name" values "value1,Value2,Value3" and on the column "Adress" values "Value4,Value5,Value6"
in this case we have :
my #matches = $str =~ /Name=(.*?)\nAdress=(.*?)\n/g;
how can we use $1 and $2 with #matches in order to get separately all occurence of Name and Adresse in order to insert them on the Table T1?

Answer 1

All captures of all matches are returned, so you'd have to group them up.
use List::Util 1.29 qw( pairs );
for ( pairs( $str =~ /Name=(.*) Address=(.*)/g ) ) {
my #matches = #$_;
...
}
That said, it's far more common to grab the matches iteratively.
while ($str =~ /Name=(.*) Address=(.*)/g) {
my #matches = ( $1, $2 );
...
}

Regex is not always the right tool for the job. Your data looks a lot like it's just key/value pairs. Use split to break it up. No need for a pattern match here.
Your code and data doesn't match, so I've gone with what the code said.
use strict;
use warnings;
my $str = <<EO_STR;
Name=Value1
Adress=Value4
Name=Value2
Adress=Value5
Name=Value3
Adress=Value6
EO_STR
my $fields;
foreach my $pair (split /\n/, $str) {
my ($key, $value) = split /=/, $pair;
$key =~ s/^\s+//;
push #{ $fields->{$key} }, $value;
}
use Data::Dumper;
print Dumper $fields;
The code will create this data structure:
$VAR1 = {
'Name' => [
'Value1',
'Value2',
'Value3'
],
'Adress' => [
'Value4',
'Value5',
'Value6'
]
};
You can now access these two array references and use them to insert data into your table.

I have done the following:
#!/usr/bin/env perl
use v5.28;
my $str = <<EO_STR;
Name=Value1 Adress=Value4
Name=Value2 Adress=Value5
Name=Value3 Adress=Value6
EO_STR
my #array;
for my $a (split(/\n/, $str)) {
my %res = $a =~ m/(\w+)=(\w+)/g;
push #array, \%res;
}
for my $a (#array) {
for my $b (sort keys %{$a}) {
"\n", <INPUT_FILE> ); say $b.'->'.$a->{$b};
}
}
It creates this structure:
#array = [
{
Name->Value1,
Adress->Value4
},
...
];
