It could be even simpler than that. Assuming operations on an array, if one can get the array into a function and decide on a regex to match the desired language:
sub func {
...
return unless my @wanted = grep m{ $rx_wanted }xms, @voices;
return $wanted[ -1 ];
}
func returns undef if no desired language is found, the last language if more than one is found, and the first if there is only one. If one didn't want the last language in the case of more than one, maybe something like
return $wanted[ @wamted > 1 ? 1 : 0 ];

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).
