不要发布您的整个代码。只发布相关部分。截至目前，你的问题是一个巨大的文字墙，大多数人只是跳过你的问题。 – Aserre

谢谢chris85。我以为我会把所有的信息放在一起，所以毫无疑问。 – Domenike

Use a parser to handle changes in HTML. XML::LibXML可以解析HTML：

#!/usr/bin/perl 
use warnings; 
use strict; 

use XML::LibXML; 

my $html = ...; # load the HTML file 
my $dom = 'XML::LibXML'->load_html(string => $html, recover => 1); 

my @delete = qw(Typography Shortcodes Tables FAQ); 
my $condition = join ' or ', map "text()='$_'", @delete; 

for my $anchor ($dom->findnodes("//a[$condition]/..")) { 
    $anchor->parentNode->removeChild($anchor); 
} 
print $dom;

它删除不只是锚，但他们的父母<li的为好。

很好的解决方案。然而，我想知道OP了解如何建立'$ condition'。 – Robert

我敢肯定XML ::的libxml会噎死的OP发布什么...第5行包含关闭'>'，但没有对应的任何'<'，他们使用自闭结束标签，例如''没有尾随斜线等 – ThisSuitIsBlackNot

@ThisSuitIsBlackNot：我只从字符串中删除了''。糟糕，它可能是样本的较旧版本，它现在可以工作。 – choroba
