I assume your database looks something like this?
entry1|entry2|entry3|entry4|entry5|
entry6|entry7|entry8|entry9|entry10|
entry11|entry12|entry13|entry14|entry15|
The easiest way to do it would be to open the file, put the data into an array, split each array element on the pipe, and then go from there.
open (DATA, "data.dat")
@data = <DATA>;
close (DATA);
foreach $item (@data)
{
@elements = split (/\|/, $item);
# do your comparisons to each item in @elements here
}
This is really an inefficient way to store data... I suggest you upgrade to a (my|postgre|donthurtme) database. Perl works really well with them, has a lot of support, and they are much faster

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).
