( #3333=superdoc: print w/ replies, xml ) Need Help??
I might do it something like this:
my $abstract = 'Perl is a high-level, general-purpose, interpreted, dynamic programming language.'; my $maxphraselength = 4; my $minphraselength = 2; my %phrasearray; my ($i,$offset); $abstract =~ s/\n|\r//g; for ($i=$minphraselength; $i<$maxphraselength; $i++) { for ($offset=0; $offset<$i; $offset++) { while ($abstract =~ /(\w+\W+){$offset}((\w+\W+){$i})/) { $phrasearray{$2}++; } } } foreach(keys %phrasearray){ print $_."\n"; } #sample output
Would that work?

Blessings,
