Because ($path, $value) is a list, you get the list of submatches (list context). But if you do something like:
if ($row =~ /(.*),(.*)/)
{
...
}
since the if expects a boolean, the operation will return true if something matches, and false otherwise (boolean context). And you can still access the left and right part as $1 and $2. So you can do:
my $path = $row; # path is the full string by default
if ($row =~ /(.*),(.*)/)
{
my $left_part = $1;
my $value = $2;
# Check if $value is a number and change $path if needed
...
}

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).
