I'm not sure if the problem I'm seeing is an artifact of sed or simply a beginner's mistake. Here's the problem: I want to add a zero-width space following each underscore between XML tags. For example, if I had the following xml:

clone
Clone(3) User Contributed Perl Documentation Clone(3)NAME
Clone - recursively copy Perl datatypes
SYNOPSIS
package Foo;
use parent 'Clone';
package main;
my $original = Foo->new;
$copy = $original->clone;
# or
use Clone qw(clone);
$a = { 'foo' => 'bar', 'move' => 'zig' };
$b = [ 'alpha', 'beta', 'gamma', 'vlissides' ];
$c = Foo->new;
$d = clone($a);
$e = clone($b);
$f = clone($c);
DESCRIPTION
This module provides a clone() method which makes recursive copies of nested hash, array, scalar and reference types, including tied
variables and objects.
clone() takes a scalar argument and duplicates it. To duplicate lists, arrays or hashes, pass them in by reference. e.g.
my $copy = clone (@array);
# or
my %copy = %{ clone (\%hash) };
SEE ALSO
Storable's dclone() is a flexible solution for cloning variables, albeit slower for average-sized data structures. Simple and naive
benchmarks show that Clone is faster for data structures with 3 or less levels, while dclone() can be faster for structures 4 or more
levels deep.
