如何在Notepad++中对不同行的指定3个字符执行查找替换？

Got it, let's break down exactly how to make those three character swaps in Notepad++—super straightforward once you use the right mode:

Step 1: Open the Replace Dialog #

Launch Notepad++, load your target text, then hit Ctrl+H to bring up the Find and Replace window.

Step 2: First Replacement (Button Arrow Swap) #

We'll target the first button's → and swap it to »:

• Make sure the Regular expression radio button is selected (this lets us match exact, specific lines without accidental changes)
• In the Find what field, paste this exact string:

  <button id="upbtn" class="btnx">→</button>
  

• In the Replace with field, paste:

  <button id="upbtn" class="btnx">»</button>
  

• Click Replace (use this instead of Replace All if you only have one instance of this button)

Step 3: Second Replacement (Link Arrow Swap) #

Now swap both <a> tag arrows from ← to «:

• Keep the Regular expression mode enabled
• In the Find what field, paste:

  <a href="#">←</a>
  

• In the Replace with field, paste:

  <a href="#">«</a>
  

• Click Replace All here—this will fix both link lines in one go

Verify the Result #

After these steps, your text should match your desired output perfectly:

<button id="upbtn" class="btnx">»</button><br><br>
<button id="downbtn" class="btny">➤</button><br>
<a href="#">«</a><br><br><br>
<a href="#">«</a><br><br><br>
