我希望从频繁的输出文档中搜索/删除一些复杂的文本。 （请参阅问题的底部以获取源文本）
使用正则表达式，我希望：
留下这样的行：1234TH-ST-TA5000-1#sh in sh 1/7/12 re
删除此：several lines of whitespace
在此行之前停止：-------------------------------
我当前的正则表达式使用环视开始匹配第一行后，但由于某种原因，它包括匹配中的第一行，只找到第一个实例（应该匹配/删除六个或七个）。
当前的RegEx：(?:(\r|\n|\r\n).+-TA5000-\d\#sh in sh \d+\/\d+\/\d+ re\b)\s+

答案 0 :(得分：2)
您可以使用
(^.+-TA5000-\d#sh in sh \d+/\d+/\d+ re$)\s+
并替换为$1\n。
请参阅regex demo。
请注意，Notepad ++ regexp不使用正则表达式分隔符，不需要转义正斜杠。
此外，NPP正则表达式默认使用多行选项，^匹配行的开头，因此，我在测试时在regex101.com启用了m选项。我还在那里启用了g选项以查找多个匹配项（模拟全部替换）。
模式详情：
(^.+-TA5000-\d#sh in sh \d+/\d+/\d+ re$) - 第1组（从替换模式引用$1反向引用）：
^ - 开始行.+ - 换行符号以外的任何1个字符-TA5000- - 文字子字符串\d - 数字#sh in sh - 文字子字符串\d+/\d+/\d+ - 1位数，/，1位数，/，1位数 re - 字面意思＆＃34;重新＆＃34;子$ - 行尾\s+ - 任何空白符号中的一个或多个（这些将被删除）。
