我需要行

Paper ID - Title (# Reviewers)

直到

Select Reviewer(s):

我这样做

use strict; 
use warnings; 

use English qw(-no_match_vars); 
use Carp; 
use HTML::TreeBuilder; 
my $f = 'index.html'; 
my $tree = HTML::TreeBuilder->new; 
$tree->parse_file($f); 

my @options = $tree->find('OPTION'); 
foreach (@options){ 
    print $_->as_text,"\n";  
} 
$tree->delete; #clear memory 
sleep(131);
后提取文本3210

但它不能提取我想要的。我无法使用结束标签。

当你尝试了代码发生了什么事做？你有什么答案是错的？你想要做什么？告诉我们更多关于你的期望和实际结果。 –

该代码给了我所有的文字，而不是那部分。当我尝试结束标签时，它不起作用。我想要两个标签之间的文本。 – CursedChico

尝试这样：

# load the page into a string, let's call it $all 
my $p0 = index($all, "Paper ID Title"); 
if ($p0 > -1) { my $p1 = index($all, "\>", $p0); 
    if ($p1 > -1) { my $p2 = index($all, "Select Reviewer(s):", $p1); 
    if ($p2 > -1) { my $target = substr($all, $p1, ($p2 - $p1)); } } }

输入文件在哪里？ – CursedChico

可以通过正则表达式

my ($required_text) = $all_string =~ /Paper ID - Title \\(\\# Reviewers\\)(.*?)Select Reviewer\\(s\\):/sg; 

Print $required_text."\n";
