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;

xmfontlistnextentry

XmFontListNextEntry(library call)										 XmFontListNextEntry(library call)

NAME

       XmFontListNextEntry -- A font list function that returns the next entry in a font list

SYNOPSIS

       #include <Xm/Xm.h>
       XmFontListEntry XmFontListNextEntry(
       XmFontContext context);

DESCRIPTION

       XmFontListNextEntry  returns  the  next entry in the font list. The application uses the XmFontListInitFontContext routine to create a font
       list context. The first call to XmFontListNextEntry sets the context to the first entry in  the	font  list.  The  application  then  calls
       XmFontListNextEntry  repeatedly	with  the  same context. Each succeeding call accesses the next entry of the font list. When finished, the
       application calls XmFontListFreeFontContext to free the allocated font list context.

       context	 Specifies the font list context

RETURN

       Returns NULL if the context does not refer to a valid entry or if it is at the end of the font list; otherwise,	it  returns  a	font  list
       entry.	If  the  function does return a font list entry, the font list entry is not a copy. Therefore, the application should not free the
       returned font list entry.
