I wanted to split a string on | characters today and ran into a little bother. My first attempt looked like this:
split "|", $str
which did not do what I expected so I tried:
split "\|", $str;
which produced exactly the same result! My last attempt was:
split "\\|", $str;
which generated the result I was after. What is going on here? The perlfunc entry for split doesn't seem to help much.
use warnings;
use strict;
my $str = "lhs|rhs";
print join " ", split "|", $str;
print "\n" . join " ", split "\|", $str;
print "\n" . join " ", split "\\|", $str;
prints:
l h s | r h s
l h s | r h s
lhs rhs
Perl is Huffman encoded by design.

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).
