Welcome to the beautiful World of XML::Twig!
Maybe this will help to get you started:
__CODE__
#!/usr/bin/perl

use warnings;
use strict;

use XML::Twig;

my $xml = join "", <DATA> ;
my $twig = XML::Twig-> new(
    twig_handlers =>  {
        name =>  sub {
            print "Found a '<name> '-Tag, Value: ", $_->text, "\n";
        },
        processName =>  sub {
            print "Found a '<processName> '-Tag, Value: ", $_->text, "\n";
        },
    },
);
$twig-> parse($xml);
__DATA__
<?xml version="1.0"?> 
<SequenceConfig xmlns="com/hnc/core/common/process/sequence/config"> 
    <name> ThisIsMySequence</name>
    <VersionInfo> 
        <author> mbuser</author>
        <version> _working</version>
        <versionDescription> </versionDescription>
        <lastModifiedDate> 1150231914745</lastModifiedDate>
    </VersionInfo> 
    <ProcessNames> 
        <processName> ILikeProcesses</processName>
        <processName> ILikeProcesses2</processName>
    </ProcessNames> 
</SequenceConfig> 
__CODE_END__

Apart from reading `perldoc XML::Twig` over and over again ( it's worth
it IMHO ), the best advice I can offer is to go here
L<http://xmltwig.com/xmltwig/tutorial/index.html>  and work yourself
through it.
