Hi all,
i have two hashes. i need 2 compare these hases & Results are stored in %different hash.
Please Help somebody.
Thanks
DK. - %hash1 = ( file1 => [
-
{
-
line => '107',
-
filename => 'SRC',
-
source => '',
-
target => [{
-
C1 => '023',
-
C2 => 'X',
-
},],
-
},
-
{
-
line => '21',
-
filename => 'SRC',
-
source => '',
-
target => [{
-
C1 => '139',
-
C2 => '221FIFTH',
-
},],
-
},
-
{
-
line => '1',
-
filename => 'SRC',
-
source => '',
-
target => [{
-
C1 => '004',
-
C2 => '101STR',
-
},],
-
},
-
]
-
-
);
-
-
%hash2 = ( file2 => [ {
-
line => '107',
-
filename => 'TRG',
-
target => '',
-
source => [
-
{
-
C1 => '023',
-
C2 => 'X',
-
},
-
],
-
},
-
{
-
line => '1',
-
filename => 'TRG',
-
target => '',
-
source => [
-
{
-
C1 => '003',
-
C2 => '101STHR',
-
},
-
],
-
},
-
{
-
line_number => '21',
-
filename => 'TRG',
-
target => '',
-
source => [
-
{
-
C1 => '1349',
-
C2 => '221FIFTH',
-
},
-
],
-
},
-
],
-
);
-
Above are 2 hashes
After comparing these two hashes, i need the results in below format - %different = ( diff => [
-
{
-
line => '1',
-
filename => 'SRC',
-
source => '',
-
target => [{
-
C1 => '004',
-
C2 => '101STR',
-
},],
-
},
-
{
-
line => '1',
-
filename => 'TRG',
-
source => [
-
{
-
C1 => '003',
-
C2 => '101STHR',
-
},
-
],
-
target => '',
-
},
-
{
-
line => '21',
-
filename => 'SRC',
-
source => '',
-
target => [{
-
C1 => '139',
-
C2 => '221FIFTH',
-
},],
-
},
-
{
-
line => '21',
-
filename => 'TRG',
-
source => [{
-
C1 => '139',
-
C2 => '221FIFTH',
-
},],
-
target => '',
-
},
-
]
-
-
);

You probably need the CPAN module Data::Compare.

Hi,
Were you able to figure out how to compare these two hashes?
I am trying to do the same and not sure how. I'm new to Perl as well.
Any help will be much appreciated.
Thanks!

You may want to examine the link referenced in the post prior to yours by Nithinpes. It is the OPs other thread and it may help you.
Regards,
Jeff

Howevrr, that link points to a thread that explains how to merge the two hashes.
I just want to compare the 2 hashes (compare all keys and values of all parent and child nodes) and print out the differences in keys, values, etc

Are the hashes simple hashes or complex hashes? A simple hash would be one level of key/value pairs, a complex hash would be anything different from that, like a hash of arrays or hash of hashes, etc. Also, what have you tried so far?

My second hash should be the same as this else I want to assert.

The other hash should be exactly the same. I just want to assert with a message and the mismatched key/value if there is any difference found in the hashes.
and Here's what I've been trying to do to compare the hashes: -
sub _compare_hashes :PRIVATE {
-
-
my ($data1, $data2) = @_;
-
my $found = 0;
-
my @missing;
-
-
foreach my $parent_node1 (keys %data1) {
-
my @childNodes1 = $parent_node1->childNodes();
-
foreach $parent_node2 (keys %data2) {
-
my @childNodes2 = $parent_node2->childNodes();
-
if ($data1{$parent_node1} eq $data2{$parent_node2}) {
-
print "Matched $data1{$parent_node1} & $data2{$parent_node2}\n";
-
} else {
-
print "Mismatched $data1{$key1}\n";
-
push @missing, $data1{$key1};
-
}
-
if ( (scalar(@childNodes1) > 1) || (scalar(@childNodes2) > 1) ) {
-
foreach my $childNode1 (@childNodes1) {
-
foreach my $childNode2 (@childNodes2) {
-
_compare_hashes($childnode1, $childnode2)
-
}
-
}
-
}
-
}
-
}
-
}
