:) That response looks parsed already :) See Re: Parsing SOAP::Lite results (with Data::Diver)

The issue is that I am not able to pull the values of tag's' like plant, material_desc etc.

Maybe you want "//MT_LABEL_IN/HEADER/*" ? IE keep doing what you're already doing?

Works for me

for my $d ( $xmlResponse->dataof("//MT_LABEL_IN/HEADER/*") ){
    print "$d   ", $d->name, " = ", $d->value, "\n",
}
__END__
SOAP::Data=HASH(0xa6a76c)   material = 12659-250GM
SOAP::Data=HASH(0xa6ab5c)   batch = D00166202
SOAP::Data=HASH(0xa6af74)   material_desc = Albumin, Bovine Serum, Fra
+ct 1PC x 250GM
SOAP::Data=HASH(0xa6b744)   plant = US05

or post code that shows that, code that runs, not fragments, maybe code like Re^3: SOAP::Lite - Attribute in array

or the acdtual xml of the response, as the DDumper you've shown doesn't have Purity(1)

This invocation of DDumper has purity

sub ppp {
    use Data::Dumper();
    return Data::Dumper->new( [@_] )->Sortkeys( 1 )->Purity( 1 )->Inde
+nt( 0 )
      ->Useqq( 1 )->Dump . '$VAR1;';
} ## end sub ppp
