Hello All,
I am having trouble splitting words from titles from a list of research
papers. I thought I could split the title into words like so:
#!/usr/local/bin/perl
use locale;
%forums = ( 1 => 'B0->K+K-Ks',
2 => 'B+->K+KsKs Decays',
3 => 'Measurement of the Total Width',
4 => 'Asymmetries in B0->K0s pi0 Decays'
);
foreach $forum ( sort keys %forums ){
my $title = $forums{$forum};
foreach $w (split /[^\w-]+/, $title) {
next unless ($w =~ /^[A-Za-z]/);
$title =~ /\b\Q$w\E\b/;
print "Journal $forum indexed word = " . ucfirst($w) . "\n";
}
}
exit;
But the results show that I'm losing some characters:
Journal 1 indexed word = B0- # this should be B0->
Journal 1 indexed word = K # what happened to the '+'?
Journal 1 indexed word = K-Ks
Journal 2 indexed word = B # '+->' missing
Journal 2 indexed word = K # '+' missing
Journal 2 indexed word = KsKs
Journal 2 indexed word = Decays
Journal 3 indexed word = Measurement
Journal 3 indexed word = Of
Journal 3 indexed word = The
Journal 3 indexed word = Total
Journal 3 indexed word = Width
Journal 4 indexed word = Asymmetries
Journal 4 indexed word = In
Journal 4 indexed word = B0- # should be 'B0->'
Journal 4 indexed word = K0s
Journal 4 indexed word = Pi0
Journal 4 indexed word = Decays
These are only example titles but the other titles have similar characters
in them as part of a "word". I tried adding the '-' and '>' to my character
class but that did not work. What am I doing wrong here?
thanks, Chee
