Just a small correction to above perl snipplet.
As far as my understanding we cannot decalre $_ as "my" since its a special global variable. This code will throw a compilation error in this case. We need to declare $_ as local to work it in proper way.
I would rather suggest using following code:-
use strict;
my $str_xml='<xml>
<email>toto@foo.com</email><name>Toto</name>
<email>tata@bar.com</email><name>Tata</name>
<email>tutu@baz.com</email><name>Tutu</name>
</xml>';
my @email = ($str_xml =~ /<email>(.*?)<\/email>/g);
my @name = ($str_xml =~ /<name>(.*?)<\/name>/g);
print "email: @email\n";
print "name: @name\n";
