If it is only backspaces you want to remove, try this:
my $text = "abcDE\x08\x08xyz\x08Z"; # \x08 is the backspace character
while ($text =~ m/\x08/g) {
substr($text, pos($text)-2, 2, '');
}
print $text, "\n"; # emits: abcxyZ
Actually, I'm a little surprised that this works. I would think that modifying
$text before the last match position in a
m//g loop would screw things up.
Update: A slightly more optimized version:
while ($text =~ m/(\x08+)/g) {
substr($text, $pos-2*length($1), 2*length($1), '');
}
print $text, "\n";

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).
