Wow thanks!
It works with LK_Keys as well:
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dump qw/ dd /;
use XML::Twig ;
my( %os, @amk );
XML::Twig->new(
twig_handlers => {
'AM_Key' => sub {
# print $_->xpath, "\n";
push @amk, $_->trimmed_text;
},
'LK_Key' => sub {
# print $_->xpath, "\n";
push @amk, $_->trimmed_text;
},
'Outpatient_Service' => sub {
# print $_->xpath, "\n";
$os{ shift @amk }++ while @amk;
},
},
)->xparse( shift );
my $ref = {
Outpatient_Services => \%os,
};
# dd $ref;
use YAML::XS();
print YAML::XS::Dump( $ref);
prints:
Outpatient_Services:
AM01: 2
AM02: 1
AM04: 1
LK01: 1
LK02: 1

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
