That's something I'd like to have in a class.
package ChargeTypeXML;
sub new
{
my $class = shift;
my %args = shift;
my $ref = XMLin($args->{file}, KeyAttr => { charge => "code"});
my %hash =
map { ($_, $ref->{charge}->{$_}->{name}) } keys %{$ref->{charge}};
$ref = \%hash;
bless $ref, $class;
return $ref;
}
sub toXML
{
print qq{<?xml version="1.0" encoding="UTF-8" ?>\n};
print qq{<charge-type-control>\n};
for keys ( %{$self} )
{
print qq{<charge code="$_" name="}, $self->{$_}, qq{frtamt"/>\n};
}
print qq{</charge-type-control>};
}
1;
#in the script:
use ChargeTypeXML;
my $xml = ChargeTypeXML->new (file=>"xmlfile");
Of course this only works, when all "codes" in the xml are unique.
Note: untested

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).

or How to display code and escape characters
are good places to start.
