I'll jump in. Here is how to use a hash slice:
$csv->print ($fh, [ $nodehash->{$_}->{nodeid},
$nodehash->{$_}->{title},
$nodehash->{$_}->{rep},
$nodehash->{$_}->{date}
]
)
# Can be written like:
$csv->print ($fh, [ @{ $nodehash->{$_} }{
qw(nodeid title rep date)
}
]
)
Note that the syntax for getting a hash slice from a reference is a bit ugly. Being able to use
$hashref->@{qw(this that other)}
has been proposed but I haven't seen a patch for it.

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).
