( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I have what I thought would be a very simple problem. However, it has me baffled. I have data of the form
"010203040506"
which I would like to split into the form of
"01 02 03 04 05 06"
. The code that I wrote

use strict; use warnings; use Data::Dumper; my @list = split(/(..)/, '010203040506'); print Dumper(\@list); print join(' ', @list)

does the job, but produces empty elements in the list, which results in the undesired output of
" 00  01  02  03  04  05  06"
which contains unwanted spaces. I understand why this is: when splitting on any two characters, the first two are a match, thus, thus they represent the split string (which is element 1), which separates a NULL string (captured in element 0) from the remaining characters (captured in remaining characters). However, I don't want to see the extra spaces in the resulting output. How can I get rid of that?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
