What I tried
#!/usr/bin/perl
use strict;
use warnings;
use Mojo::DOM;
open (my $fh, "<", "y.html") or die $!;
my $dom = Mojo::DOM->new(do{local $/ = undef; <$fh>});
$dom->find("*")->each( sub { $_->content( $_->content =~ s/\s/\ /gr ) } );
print $dom;
Result from above script

I'm not getting the desired output, it's adding in tag also (eg: </span ), I want that to be done only on the content.
PS: I tried it with Mojo::DOM, but it's not necessary to use it, you can try any other parser if you want, still I would like to know what's wrong with my code?

This is a job where tokenizing the input makes it easier to work with. I therefore advise using HTML::TokeParser
#!/usr/bin/perl
use strict;
use warnings;
use utf8;
use HTML::TokeParser;
my $data = do {local $/; <DATA>};
my $p = HTML::TokeParser->new(\$data);
while (my $token = $p->get_token) {
if ($token->[0] eq 'T') {
my $text = $token->[1];
$text =~ s/ / /g;
print $text;
} else {
print "$token->[-1]";
}
}
