Code:
perldoc -f split

Splits the string EXPR into a list of strings and returns the list in list context, or the size of the list in scalar context.

In Perl is important to get familiar with the concept of context. You'll live or die by the scalar or list context.

split is for a string. You gave it a list.
Code:
my @parts = split /<?xml version/, @lines;

This snip has the essence of what you were trying to learn.
The result will show the reason why, ultimately, it will not split as you expect in order to have separated files.
Code:
#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper qw(Dumper);

sub usage {
    print "Usage: $_[0] <filename>\n";
    exit;
}
#
# $0 is always the name of the program
#
my $filename = shift or usage $0;

# Same:
# my $filename = shift @ARGV or usage $0;

open my $fh, '<', $filename or die "$!\n";
     # change the separator to empty and read
     # the whole file as a string
     local $/;
     my @content = split /<?xml version/, <$fh>;
close $fh;

print Dumper \@content;

xml::xpath::node::element

XPath::Node::Element(3) 				User Contributed Perl Documentation				   XPath::Node::Element(3)

NAME

       Element - an <element>

API

   new ( name, prefix )
       Create a new Element node with name "name" and prefix "prefix". The name be "prefix:local" if prefix is defined. I know that sounds wierd,
       but it works ;-)

   getName
       Returns the name (including "prefix:" if defined) of this element.

   getLocalName
       Returns just the local part of the name (the bit after "prefix:").

   getChildNodes
       Returns the children of this element. In list context returns a list. In scalar context returns an array ref.

   getChildNode ( pos )
       Returns the child at position pos.

   appendChild ( childnode )
       Appends the child node to the list of current child nodes.

   getAttribute ( name )
       Returns the attribute node with key name.

   getAttributes / getAttributeNodes
       Returns the attribute nodes. In list context returns a list. In scalar context returns an array ref.

   appendAttribute ( attrib_node)
       Appends the attribute node to the list of attributes (XML::XPath stores attributes in order).

   getNamespace ( prefix )
       Returns the namespace node by the given prefix

   getNamespaces / getNamespaceNodes
       Returns the namespace nodes. In list context returns a list. In scalar context returns an array ref.

   appendNamespace ( ns_node )
       Appends the namespace node to the list of namespaces.

   getPrefix
       Returns the prefix of this element

   getExpandedName
       Returns the expanded name of this element (not yet implemented right).

   string_value
       For elements, the string_value is the concatenation of all string_values of all text-descendants of the element node in document order.

   toString ( [ norecurse ] )
       Output (and all children) the node to a string. Doesn't process children if the norecurse option is a true value.
