Could this be resolved with a regex maybe? Like for example:
#!/usr/bin/perl
use strict;
use warnings;
my $PATH = 'http://a.com/a/b/c/d/e.json?something' . '/' . '/../../../
+';
$PATH =~ tr|/||s;
my $PREV = 0;
my $LEN;
for (;;)
{
$PATH =~ s/\/[^\/]+\/\.\.//;
$LEN = length($PATH);
last if ($PREV == $LEN);
$PREV = $LEN;
}
print $PATH;
I put the regex in a for(;;) loop, because adding global flag didn't do what I want:
$PATH =~ s/\/[^\/]+\/\.\.//g;

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).
