问题描述
我正在使用 Notepad++，基本上我想使用 Notepad++ 正则表达式查找所有 不包含文本的空白行.我知道使用textfx"有一种更简单的方法可以做到这一点，但我正在寻找一种表达方式来做到这一点.以下是显示符号的示例.
I'm using Notepad++ and basically I want to find all blank lines that don't contain text using Notepad++ regex. I know that there is a simpler way of doing this by using 'textfx,' but I'm looking for an expression to do this. Here is an example below with the symbols shown.
< ?php **CRLF**
**CRLF** *<- REMOVE THIS*
$xxx = $_POST['xxx'];**CRLF**
$xxx = $_POST['xxx'];**CRLF**
$xxx = $_POST['xxx'];**CRLF**
**CRLF** *<- REMOVE THIS*
**CRLF** *<- REMOVE THIS*
if ($xxx)**CRLF**
{**CRLF**
推荐答案
不是正则表达式，但 Notepad++ 6.3.2 有多种方法可以在不使用正则表达式的情况下删除空行.
Not a regular expression, but Notepad++ 6.3.2 has a number of ways of removing blank lines without using a regular expression.
Menu => 编辑 => 行操作 => 删除空行
Menu => Edit => Line operations => Remove empty lines
Menu => Edit => 行操作 => 删除空行(包含空白字符)
Menu => Edit => Line operations => Remove empty lines (containing blank characters)
Menu => TextFx => TextFx Edit => 删除空行
Menu => TextFx => TextFx Edit => Delete blank lines
Menu => TextFx => TextFx Edit => 删除多余的空行
Menu => TextFx => TextFx Edit => Delete surplus blank lines
两个TextFx方法只删除空行，但可以在它们前面加上:
The two TextFx methods only delete empty lines, but they can be preceded with either of:
菜单 => 编辑 => 空白操作 => 修剪尾随空格
Menu => Edit => Blank operations => Trim trailing spaces
Menu => TextFx => vTextFx Edit** => 修剪尾随空格
Menu => TextFx => vTextFx Edit** => Trim trailing spaces
