使用している Perl コードが機能しHTML::TableExtractません。
これが私のコードです
#!/usr/bin/perl
use strict;
use warnings;
use HTML::TableExtract;
## Exactract table from html file
my $te = new HTML::TableExtract( attribs => { border => 0} );
$te->parse_file("file_path.html");
my $table = $te->tables;
for my $row ($table->rows) {
print join(',', @$row), "\n";
}
このエラーが発生し続けます
Can't call method "rows" without a package or object reference at ./parse_table.pl line 13.
これが私のHTMLファイルで、興味のあるテーブルだけを表示するために切り詰められています。 http://phucnvo.myvnc.com/sandbox/out.html
