Replace 如何用换行符替换第一个空格后的大写字母？

所以我有这篇文章（它有一千多行）：

我希望它是这样的：

ABO blood group antigens
Carbohydrate antigens attached mainly to cell surface proteins or lipids that are present on many cell types, including red blood cells. These antigens differ among individuals, depending on inherited alleles encoding the enzymes required for synthesis of the carbohydrate antigens. The ABO antigens act as alloantigens that are responsible for blood transfusion reactions and hyperacute rejection of allografts.

Acquired immunodeficiency
A deficiency in the immune system that is acquired after birth, usually because of infection (e.g., AIDS), and that is not related to a genetic defect. Synonymous with secondary immunodeficiency.

Acquired immunodeficiency syndrome (AIDS)
A disease caused by human immunodeficiency virus (HIV) infection that is characterized by depletion of CD4+ T cells, leading to a profound defect in cell-mediated immunity. Clinically, AIDS includes opportunistic infections, malignant tumors, wasting, and encephalopathy.

Activation-induced cell death (AICD)
Apoptosis of activated lymphocytes, generally used for T cells.

Activation-induced (cytidine) deaminase (AID)
An enzyme expressed in B cells that catalyzes the conversion of cytosine into uracil in DNA, which is a step required for somatic hypermutation and affinity maturation of antibodies and for Ig class switching.

Activation protein 1 (AP-1)
A family of DNA-binding transcription factors composed of dimers of two proteins that bind to one another through a shared structural motif called a leucine zipper. The best-characterized AP-1 factor is composed of the proteins Fos and Jun. AP-1 is involved in transcriptional regulation of many different genes that are important in the immune system, such as cytokine genes.

有办法绕过它吗？我不是程序员。谢谢。

我在本地测试了你的文本，效果很好，我不是正则表达式专家，所以它可能不是最有效的

使用“替换”选项卡（

Ctrl+H

）：

查找内容：

^（.*）（[A-Z].$）

替换为：

\1\r\n\2

确保选中了匹配大小写和正则表达式

说明：
查找内容：

^           starts with
.           anything
*           repeated 0 or more times
?           lazy match so that it stops at the capital letter (next group)
(.*?)       remember that part (group 1)
            followed by a space
[A-Z]       match the capital letter
.           anything
*           repeated 0 or more times
$           ends with
([A-Z].*$)  remember that part (group 2)

取代

\1          group 1
\r          carriage return
\n          new line
\2          group 2

您需要使用（查找后跟大写字母的空格）进行替换

在记事本++中，使用正则表达式查找/替换（确保选中“匹配大小写”）

查找内容：（[^.]）（[A-Z]） 替换为：\1\r\n\2

是

使用perl脚本。这一个让我觉得

#!/usr/bin/perl
$cestbon = 0;
while (<>) {
@line = split(" ",$_);
if (/^$/) {
            $cestbon = 0;
    print "\n";
    }
foreach (@line) {
    if (/\b[A-Z][a-z0-9]*\b/ && $cestbon < 2) {
      print "\n$_ ";
      $cestbon++;
    } else {
      print "$_ ";
    }
}
}

可能不太完美，但我在10分钟内就写好了，让我休息一下：）

我不知道你在那里做了什么，但它很有魅力！非常感谢你！

#!/usr/bin/perl
$cestbon = 0;
while (<>) {
@line = split(" ",$_);
if (/^$/) {
            $cestbon = 0;
    print "\n";
    }
foreach (@line) {
    if (/\b[A-Z][a-z0-9]*\b/ && $cestbon < 2) {
      print "\n$_ ";
      $cestbon++;
    } else {
      print "$_ ";
    }
}
}
