How can I extract specific texts from an HTML file by using Notepad++ or Adobe Dreamweaver?

问题

I want to extract the ID attribute from an HTML file by using Notepad++ or Dreamweaver. Delete all other texts.

For Eg:

<div id="header" class="header-blue sticky">
<div id="header-message" class="alert alert-dismissible">
<form id="contact-form" class="custom-form" method="POST" action="https://www.google.com">
<input id="your-email" type="email" class="form-email"  placeholder="Your Email">

I want to extract only ID attribute from HTML like this;

id="header"
id="header-message"
id="contact-form"
id="your-email"

So what I can do? Please help me..

回答1:

Ctrl+H
Find what: <\w+[^>]+(id=".+?").*?>
Replace with: $1
CHECK Wrap around
CHECK Regular expression
Replace all

Explanation:

<\w+            # opening tag
[^>]+           # 1 or more not >
(id=".+?")      # group 1, id and value
.*?             # 1 or more any character, not greedy
>               # close tag
