I want to extract sequences of words according to how many characters in each word.
So I want to extract for instance a sequence based on the number of characters (here defined as letters of the alphabet - not punctuation, numbers, white space).
For instance: I want sequences of 2, 4 and 3 character words - in that order only (but it could be any numbers of characters in any order I choose).
Say my text is: "xxxx yy zzzzz xxxx qqq"
I should extract the sequence: "yy xxxx qqq"
and keep on doing it. So from "xxxx yy zzzzz xxxx qqq xxxx yy zzzzz xxxx qqq"
I should extract
"yy xxxx qqq yy xxxx qqq"
my $string = "xxxx yy zzzzz xxxx qqq";
my @array = ( $string =~ /(\b..?\b) (\b....?\b) (\b...?\b)/sg );
# produces nothing.
# I have also tried rewriting it without success: it may
# produce results, but not the right ones! (not the exact
# also if the string were longer it should produce
# the sequence repeated:
# "xxxx yy zzzzz xxxx qqq xxxx yy zzzzz xxxx qqq"
# should produce "yy xxxx qqq yy xxxx qqq" etc etc
# until we run out of text.
I have also tried running adaptions of remiah's code,
but without success: http://www.perlmonks.org/?node_id=996670.
The problem/task differs and I cannot adapt the code to it. Inability!
nicemank thanks in advance!
