You need to add the encoding used in the document at the start of it: <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>. The entities are then converted to the proper numerical entities.
You may also want to use mirod's XML::Twig, which, in the
latest version (3.0) is able to keep the original encoding. And besides this cool feature, I find Twig easier to use than DOM to process XML docs. Here's what your code would look like with Twig:
#!/usr/bin/perl -w
use strict;
use XML::Twig 3.0;
my $parser = new XML::Twig( keep_encoding => 1 );
my $xmlstring=<<"XMLEND";
<?xml version="1.0" encoding="ISO-8859-1"?>
<ACTION>
<INPUT LABEL="Radio Button"/>
<INPUT LABEL="été"/>
<RADIO ID="List">
éééàààùùù
</RADIO>
</ACTION>
XMLEND
$parser->parse($xmlstring);
$parser->print;
Hope this helps!
update: version 3.0 of XML::Twig can be found here

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).
