how can i parse perl json object which has spaces in its keys
{
"abc" : [
"lmn" : {
"Ab Cd" : "Xy Zw",

Answer 1

By definition, one parses JSON using a JSON parser. There exists multiple JSON parsers on CPAN, including Cpanel::JSON::XS. It handles keys with spaces in them without issue, as should every other JSON parser.
Note that what you have isn't JSON. I'm assuming the errors are typos since you asked about JSON.

Answer 2

Spaces in a key will present no problems at all to any JSON parser.
There are, however, two problems in your JSON that will cause problems for any parser. Others have noted the extra comma after "Pq Rs", but you also have an array that contains a key/value pair (with the key "lnm") which needs to be inside an object.
Originally, I just removed the comma and ran this code:
#!/usr/bin/perl
use strict;
use warnings;
use feature 'say';
use Data::Dumper;
use JSON;
my $json = '{
"abc" : [
"lmn" : {
"Ab Cd" : "Xy Zw",
"Ef Gh" : "Pq Rs"
}
]
}';
my $data = decode_json($json);
say Dumper $data;
This gives an error:
, or ] expected while parsing array, at character offset 28 (before ": {\n "Ab C...")
I fixed it, by inserting { ... } around the lnm object.
#!/usr/bin/perl
use strict;
use warnings;
use feature 'say';
use Data::Dumper;
use JSON;
my $json = '{
"abc" : [ {
"lmn" : {
"Ab Cd" : "Xy Zw",
"Ef Gh" : "Pq Rs"
}
} ]
}';
my $data = decode_json($json);
say Dumper $data;
And then I got this output:
$VAR1 = {
'abc' => [
{
'lmn' => {
'Ab Cd' => 'Xy Zw',
'Ef Gh' => 'Pq Rs'
}
}
]
};
Which is, I think, what you are expecting.
