Struggling to combine two Greps statements
Greetings!

I have been tasked to create a report off files we receive from our hardware suppliers. I need to grep these files for two fields 'Test_Version' and 'Model-Manufacturer' ; for each field, I need to capture their corresponding values.

When running each statement separately, I get the results I want:

1) for 'Test_Version', it was straightforward:

Code:
    find . -name "*.VER" -exec grep 'Test_Version=' '{}' ';' -print; 

    ./(FILE_NAME).VER
    Test_Version=2.6.3
    ./(FILE_NAME).VER
    Test_Version=2.4.7

2) for 'Model-Manufacturer', , it was a bit tricky since what I need is across multiple lines. I solved this issue by using Perl Regex option -P.

Code:
    find . -name "*.VER" -exec grep -P 'Model-Manufacturer:.\n.' '{}' ';' -print

    ./(FILE_NAME).VER
    --> Model-Manufacturer:
    D12-100
    ./(FILE_NAME).VER
    --> Model-Manufacturer:
    H21-100

Ideally, I would like to create a simple report that looks like this

Code:
    (FILE_NAME)
    Test_Version=2.6.3
    Model-Manufacturer:    D12-100
    (FILE_NAME)
    Test_Version=2.4.7
    Model-Manufacturer:    H21-100


My attempt to combine both greps is not working i.e nothing is found:

Code:
    find . -name "*.VER" -exec grep -P 'Test_Version=.Model-Manufacturer:.\n.' '{}' ';' -print

How can I grep to search for both fields and produce the output I want?

RDF::Trine::Model::StatementFilter(3pm) 		User Contributed Perl Documentation		   RDF::Trine::Model::StatementFilter(3pm)

NAME

       RDF::Trine::Model::StatementFilter - Model for filtering statements based on a user-specified criteria

VERSION

       This document describes RDF::Trine::Model::StatementFilter version 1.000

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Trine::Model class.

       "new ( $store )"
	   Returns a new statement-filter model.

       "count_statements ($subject, $predicate, $object)"
	   Returns a count of all the statements matching the specified subject, predicate and objects. Any of the arguments may be undef to match
	   any value.

       "get_statements ($subject, $predicate, $object [, $context] )"
	   Returns a stream object of all statements matching the specified subject, predicate and objects from all of the rdf stores. Any of the
	   arguments may be undef to match any value.

       "get_pattern ( $bgp [, $context] )"
	   Returns a stream object of all bindings matching the specified graph pattern.

       "apply_rules ( $statement )"
       "rules"
	   Returns a list of all rules in the inferencing model.

       "add_rule ( &rule )"
	   Adds a rule to the inferencing model. The rule should be a CODE reference that, when passed a statement object, will return true if the
	   statement should be allowed in the model, false if it should be filtered out.
