Merging the two output files on the shell level should not be considered the smartest approach as SQL has the means - and is designed to do exactly that - to do the merge immediately in a query. Try like (my SQL has become somewhat rusty, so there may be smarter queries):
Need to find only unique values for a given tag across the files:
For eg:
Test1:
<Tag1>aaa</Tag1>
<Tag2>bbb</Tag2>
<Tag3>ccc</Tag3>
Test2:
<Tag1>aaa</Tag1>
<Tag2>ddd</Tag2>
<Tag3>eee</Tag3>
Test3:
<Tag1>aaa</Tag1>
<Tag2>ddd</Tag2>
<Tag3>eee</Tag3>

class::dbi::abstractsearch
Class::DBI::AbstractSearch(3pm) User Contributed Perl Documentation Class::DBI::AbstractSearch(3pm)NAME
Class::DBI::AbstractSearch - Abstract Class::DBI's SQL with SQL::Abstract::Limit
SYNOPSIS
package CD::Music;
use Class::DBI::AbstractSearch;
package main;
my @music = CD::Music->search_where(
artist => [ 'Ozzy', 'Kelly' ],
status => { '!=', 'outdated' },
);
my @misc = CD::Music->search_where(
{ artist => [ 'Ozzy', 'Kelly' ],
status => { '!=', 'outdated' } },
{ order_by => "reldate DESC",
limit_dialect => 'LimitOffset',
limit => 1
offset => 2 });
DESCRIPTION
Class::DBI::AbstractSearch is a Class::DBI plugin to glue SQL::Abstract::Limit into Class::DBI.
METHODS
Using this module adds following methods into your data class.
search_where
$class->search_where(%where);
Takes a hash to specify WHERE clause. See SQL::Abstract for hash options.
$class->search_where(\%where,\%attrs);
Takes hash reference to specify WHERE clause. See SQL::Abstract for hash options. Takes a hash reference to specify additional query
attributes. Class::DBI::AbstractSearch uses these attributes:
o order_by
Array reference of fields that will be used to order the results of your query.
o limit_dialect
Scalar, DBI handle, object class, etc. that describes the syntax model for a LIMIT/OFFSET SQL clause. Please see
SQL::Abstract::Limit for more information.
o limit
Scalar value that will be used for LIMIT argument in a query.
o offset
Scalar value that will be used for OFFSET argument in a query.
Any other attributes are passed to the SQL::Abstract::Limit constructor, and can be used to control how queries are created. For
example, to use 'AND' instead of 'OR' by default, use:
$class->search_where(\%where, { logic => 'AND' });
