Hello Monks,
I need your help.
I have an array containing sentences. I want to order the sentences according to a given word (i.e. the third from the left).
I am a nice boy
You are a nice boy
They are not good at all
What I found is the following (adapting it from Lingua::Concordancer):
sub order_line{
my @sorted_lines;
foreach ( sort { _by_left( $a, $b ) } @lines ) { push @sorted_line
+s, $_ }
print @sorted_lines;
}
sub _by_left {
my ( $a, $b ) = @_;
return lc( _on_left( $a )) cmp lc( _on_left( $b ));
}
sub _on_left {
my ( $s ) = @_;
my @words = split( /\s+/);
my $word_level=3;
return $words[ scalar( @words ) - $word_level ];
}
Of course it doesn't work...

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
