I have written below script to retrieve BLOB data ( which has XML format) from oracle 11g, IF I run the Select statement in the query builder in some tool (i.e. ORACLE SQL Developer) it is giving me the BLOB values which is XML. Now I want to write a perl script which will invoke the BLOB as XML and print it on my screen.

#!/usr/bin/perl
use strict;
use warnings;
use DBI;
use DBD::Oracle;


my $dbh = DBI->connect('dbi:Oracle:host=<IP ADRESS>;sid=11G;port=1521'
+,'username', 'password', { RaiseError => 1, AutoCommit => 0 }) or die
+ "can not connect to the DB";

my $sth = $dbh->prepare(qq{select xmltype(SERVICE_SPECIFIC_DATA_V,871)
+ from CONNECTION_ACCOUNTS where account_id_n = 1462});

$sth->execute();

while ( my ($SERVICE_SPECIFIC_DATA_V) = $sth->fetchrow() )

{
     print STDOUT "BLOB is: $SERVICE_SPECIFIC_DATA_V\n";
}
$sth->finish();
$dbh->disconnect;

Output of this program is :

BLOB is :ARRAY(0xdd705a0)

How Can I print the SERVICE_SPECIFIC_DATA_V xml values. or is there any alternative way where I can do it easily. Also, If I want to Insert or update this BLOB column which has XML, need Monks valuable suggestion on this. Thanks.
