正则表达式结果为多个匹配输出单个匹配答案

【问题标题】：Regex result outputs single match for multiple matches正则表达式结果为多个匹配输出单个匹配
【发布时间】：2019-06-19 13:23:58
【问题描述】：

我在“错误消息”字段中有一个包含多个换行符的文件。我需要将换行符替换为空格，以便将其加载为单行。

但我无法捕获多个匹配项。我的正则表达式为整个文件输出单个匹配项。我需要帮助来创建正则表达式，这将为我提供的示例提供 3 个匹配项。

使用正则表达式

^breakmantis.*;(Error;[\s\S]*;Regular;)[\s\S]*breakmantis

**带有换行符的当前文件：**

name;brand;environment;center;Error
breakmantis;Kordel;Production;Bleep Eyeglow;Error;"The message did not pass the validation: 
Error Message='PriceTag' is mandatory, under field Price.
Error Message='PriceAmount' is mandatory, under field Price.
Error Message='BaseQuantity' is mandatory, under field Price.";Regular;;;;24 Apr 2019 14:34 CEST
breakmantis;Kordel;Production;Bleep Eyeglow;Error;"The message did not pass the validation: 
Error Message='PriceTag' is mandatory, under field Price.
Error Message='PriceAmount' is mandatory, under field Price.
Error Message='BaseQuantity' is mandatory, under field Price.";Regular;;;;24 Apr 2019 14:35 CEST
breakmantis;Kordel;Production;Bleep Eyeglow;Error;"The message did not pass the validation: 
Error Message='PriceTag' is mandatory, under field Price.
Error Message='PriceAmount' is mandatory, under field Price.
Error Message='BaseQuantity' is mandatory, under field Price.";Regular;;;;24 Apr 2019 14:36 CEST

预期结果：

breakmantis;Kordel;Production;Bleep Eyeglow;Error;"The message did not pass the validation: Error Message='PriceTag' is mandatory, under field Price.Error Message='PriceAmount' is mandatory, under field Price.Error Message='BaseQuantity' is mandatory, under field Price.";Regular;;;;24 Apr 2019 14:34 CEST

怎么样？

^breakmantis.*;(Error;[\s\S]*?)CEST$

感谢您的快速回答。诀窍来了“*？”返回多个匹配项的量词。我没想过使用“？”匹配器最初。这对我有帮助。

【解决方案2】：

尝试匹配：

\n（错误消息=）

并替换为

\1

在替换中添加前导空格以满足您的需要。
