这似乎是一个常见问题，提供的解决方案是:

Simple search (Ctrl+H) without regexp You can turn on View/Show End of Line or view/Show All, and select the now visible newline characters. Then when you start the command some characters matching the newline character will be pasted into the search field. Matches will be replaced by the replace string, unlike in regex mode. Note 1: If you select them with the mouse, start just before them and drag to the start of the next line. Dragging to the end of the line won't work. Note 2: You can't copy and paste them into the field yourself. Advanced search (Ctrl+R) without regexp Ctrl+M will insert something that matches newlines. They will be replaced by the replace string.

我发现它的工作方式是使用替换功能，并使用“\n”，与“扩展”模式。我使用的是5.8.5版本。

我在查找/替换窗口中使用\r\n个正则表达式时运气不太好。

然而，这适用于notepad++ v4.1.2:

Use the "View | Show end of line" menu to enable display of end of line characters. (Carriage return line feeds should show up as a single shaded CRLF 'character'.) Select one of the CRLF 'characters' (put the cursor just in front of one, hold down the SHIFT key, and then pressing the RIGHT CURSOR key once). Copy the CRLF character to the clipboard. Make sure that you don't have the find or find/replace dialog open. Open the find/replace dialog. The 'Find what' field shows the contents of the clipboard: in this case the CRLF character - which shows up as 2 'box characters' (presumably it's an unprintable character?) Ensure that the 'Regular expression' option is OFF.

现在您应该能够根据需要进行计数、查找或替换。

将一个由多行组成的文档改为一行，每行组成逗号分隔的列表中的一个条目:

按Ctrl +f打开搜索/替换。 点击“替换”页签。 用“\r\n”填充“Find what”条目。 用“，”或“，”(取决于偏好)填充“Replace with”条目。 取消选中“匹配整个单词”复选框(回避逻辑的重要部分)。 检查“扩展”单选按钮。 点击“全部替换”按钮。

这些步骤转向。

成:

或者:(取决于个人喜好)

Foo bar, bar baz, baz Foo

如果你需要做一个复杂的regexp替换，包括\r\n，你可以通过三步方法来解决这个限制:

将所有的\r\n替换为一个标签，例如#GO#→检查'Extended'，将\r\n替换为#GO# 执行regexp，例如从html书签中删除多行ICON="*"→检查regexp，替换ICON=.[^"]+。> by > 返回\r\n→勾选“扩展”，将#GO#替换为\r\n
