So, I don't understand why $cell->as_text gives the data, when Dumper \@cells prints a giant ton of garbage. Also, even though I have specified the table element as
my @tables = $tree->findnodes('//table');
my $table = $tables[12];
I cant reference this directly. Printing @cells[2]->as_text fails outright with "can't call method 'as_text' on an undefined value". It is clearly in there as
my @cells = $row->findnodes('td')
.... Anything I do to @cells flat out fails except for looking through with the mentioned
for my $cell (@cells)...
print $cell->as_text
At this junction, I am about to totally give up on this, since I do not understand this at all and have no other way I can parse this otherwise. Since as_text dumps this one entry at a time, I was hoping to process the even elements of @cells as host/ip address and the odd as the previous elements port. But I just don't get this at all.

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).
