【问题描述】：
我的文本包含两种类型的 cmets。由% 分隔的那些以及以/* 开头并以*/ 结尾的那些。例如：
输入1：
Sarah was going out. % Remember she usually doesn't go out % It was very cold.DESIRED_OUTPUT1：
Sarah was going out. It was very cold.输入2：
Sarah was going out. /* Remember she usually doesn't go out */ It was very cold.DESIRED_OUTPUT2：
Sarah was going out. It was very cold.输入3：
Charles knocked on the door and a woman opened it. % Hmm, is this good... /* Not sure */ Perhaps this should happen in chapter 10 instead? % She looked at him. - Yes?, she said.DESIRED_OUTPUT3：
Charles knocked on the door and a woman opened it. She looked at him. - Yes?, she said.输入4：
Charles knocked on the door and a woman opened it. % Hmm, is this good... /* Not sure to 100% */ Perhaps this should happen in chapter 10 instead? % She looked at him. - Yes?, she said.DESIRED_OUTPUT4：
Charles knocked on the door and a woman opened it. */ Perhaps this should happen in chapter 10 instead?
基本上，我希望在遇到开始注释标记时，所有内容都被删除，直到其各自的结束注释标记（即使这意味着删除其他类型的注释标记）。
如果使用% 或/* 打开评论，但从未关闭，则假定评论将持续到文本结尾。但是，如果它只是出现这种*/ 的结束标记（因为开启者在另一个评论中，因此被删除），它应该留在文本中。

我认为输入 4 的结果应该是
Charles knocked on the door and a woman opened it. */ Perhaps this should happen in chapter 10 instead? % She looked at him. - Yes?, she said.。你似乎想要.replaceAll("%[^%]*%|/\\*[^*]*\\*+(?:[^/*][^*]*\\*+)*/","")。不过，您可能需要将最后一个%设为可选"%[^%]*%?|/\\*[^*]*\\*+(?:[^/*][^*]*\\*+)*/"。 -
嗯，感谢您指出这一点。我忘了提到是否没有结束标记（或者只是一个结束标记，因为开口在另一个评论中，因此被删除，就像在这种情况下一样）标记应该留在那里。所以输入/输出4是正确的。
-
所以，acc。根据您所说的（“标记应该留在那里”），不应在输入 4 中删除
% She looked at him. - Yes?, she said.。 -
嗯，你又是对的。如果使用 % 或 / * 打开评论，但从未关闭，则假定评论将持续到文本结尾。
-
啊哈，所以你可能想要
.replaceAll("%[^%]*%?|/\\*[^*]*(?:\\*(?!/)[^*]*)*(?:\\*/)?","")
