Question

如何更换＆＃34; images /＆＃34;一个HTML文件到一些其他单词（即＆＃34; bebe＆＃34;）？

这是我的代码，但它不起作用：

#!/usr/bin/perl
########################################## Carrega Modulos

use LWP::UserAgent;
use LWP::Simple;

$ua = new LWP::UserAgent;
$ua->agent('Mozilla/5.0 (X11; U; NetBSD i386; en-US; rv:1.8.1.12) Gecko/20080301 Firefox/2.0.0.12');

my $pedido1 = new HTTP::Request GET =>"http://localhost/site1/index.html";
my $resposta1 = $ua->request($pedido1) or die "Erro no site scanner\n"; 
my $res1 = $resposta1->content;
open (OUT, ">>hit.txt"); print OUT "$res1\n"; close(OUT); $cont=$cont+1;
$res1 =~ s/"images"/"bebe"/g;
print $res1;

这是我的HTML：

Answer 1

假设失败发生在REGEX。

从正则表达式中删除引号。

$res1 =~ s/images/bebe/g;

编辑：看看inferno的评论，你可能会想要这个。它将匹配src和数据源属性中的图像。

$res1 =~ s/(src|data-source)="images\//$1="bebe/g;

请注意，这是在＆＃39;图像＆＃39;之后删除正斜杠。所以，如果这不是您的意图，您可以删除该模式的那一部分或将其重新添加到替换方。

选项＃1

$res1 =~ s/(src|data-source)="images/$1="bebe/g; # Removed from pattern

选项＃2

$res1 =~ s/(src|data-source)="images\//$1="bebe\//g; # Added back in on replacement
