And so on..
So far i've written this code but i can't realize why it doesn't work. It prints nothing to both screen and text file. Any help will be appreciated.Thank you!
use strict;
use warnings;
use HTML::TreeBuilder;
my $tree = HTML::TreeBuilder->new_from_content(
do { local $/; <DATA> }
);
open(my $fh, '>', 'outputs.txt');
my $i = 2;
for ( $tree->look_down( 'name' => 'papers' ) ) {
my $papers = $_->look_down( 'OPTION value' => 'i' )->as_trimmed_text;
# my $comment = $_->look_down( 'class' => 'content' )->as_trimmed_text;
# my $name = $_->look_down( '_tag' => 'h3' )->as_trimmed_text;
# $name =~ s/^Re:\s*//;
# $name =~ s/\s*$location\s*$//;
print "Paper: $papers\n";
print $fh "Paper: $papers\n";
$i++;
}

We use Perl filehandle to read its content. we should always close the filehandle after processing it. text from test2.txt file C:\> “text from test2.txt file” is the content of the test2.txt file.
You must put space between print (), filehandle FH and $str variable. The $str variable holds data that is written to the file. Notice that if you write to a file that contains content, Perl will truncate its content. As always, you should close the filehandle when you are no longer use it.
Perl read file in scalar context. In order to read from a file in read mode, you put the filehandle variable inside angle brackets as follows: To read the next line of the file with newline included, you use the following syntax: $line = <FH>;
The Perl source code file path is c:\perlws\perl-read-file2.pl Now, you can invoke the program from the command line as follows:
You're overcomplicating with the look_down, which is used for attributes. Simply find() the <option> elements.
foreach my $papers ( $tree->look_down( 'name' => 'papers[]' ) ) {
foreach my $option ( $papers->find( 'option' ) ) {
say $option->as_trimmed_text;
}
}
Also note that the name attribute of the <select> is papers[], not papers. The [] are part of the name.

Try this:
#! /usr/bin/env perl
use strict;
use warnings;
use HTML::TreeBuilder;
my $tree = HTML::TreeBuilder->new_from_content(
do { local $/; <DATA> }
);
# $tree->dump;
for ( $tree->look_down( 'name' => 'papers[]' ) ) {
for my $p ( $_->look_down( '_tag' => 'option' ) ) {
print "Paper: " . $p->as_trimmed_text( extra_chars => '\xA0' ) . "\n";
}
}
__DATA__
...
There are two problems with your code: the interesting section is named papers[], not papers (I used $tree->dump to find that out), and both the arguments and the return value of your second look_down() are completely messed up. I'm not sure why you expected that to work.
