I am attempting to extract information from a text file across a number of lines.I can't find the correct regular expression syntax to match when it comes across = or () or '.' or any other non-alphanumeric characters.
'.' only seems to match alphanumeric characters.Can anyone help me?
ie:
#! /usr/bin/perl
use strict;
my $string = "LOCUS SOY4KDPP 545 bp PLN 01-FEB-2000
DEFINITION BIO5 gene complete cds EC=1.7.7.1.
ACCESSION D17396
VERSION D17396.1 GI:498167
KEYWORDS protein; insulin-like protein;
leginsulin.
//";
if ($string =~ /DEFINITION\s\s([\w\s]+)ACCESSION/){
print "$1\n";
}
exit;

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).
