gri6507 has asked for the wisdom of the Perl Monks concerning the following question:
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
does the job, but produces empty elements in the list, which results in the undesired output ofuse strict; use warnings; use Data::Dumper; my @list = split(/(..)/, '010203040506'); print Dumper(\@list); print join(' ', @list)
" 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?
