正则表达式移动答案反馈到答案之前?

Question

我为题库准备了一些文本问题。它们需要重新格式化，我不知道如何在问题和答案选项之间移动反馈。反馈以"@"开头。"*"表示正确答案。最初的反馈只针对一个正确的答案，但我们的新LMS只支持任何不正确的答案的一般反馈。我如何将@后面的反馈文本移动到第一个答案选择之前?

Answer 1

您可以通过使用正则表达式^(d+).*nn)((?:*?[a-z]. .*n)*)(@ .*n.*n)((?:*?[a-z]. .*n)*)和替换字符串$1$3n$2$4来做到这一点。

这里regex的意思是:

• ^(d+).*nn)行，以数字、右括号和空格开头，后跟两行，
• ((?:*?[a-z]. .*n)*)行以可选的*、字母、点和任意数量的任意符号开头，重复任意次数。任意数量的答案。
• (@ .*n.*n)两行，首先以@(feedback)
开头
• ((?:*?[a-z]. .*n)*)和以前一样

替换的演示可以在这里看到。此外，您还可以修补替换字符串，因为您没有提供足够的输入来可靠地猜测期望的输出。

要使用此功能，请使用VScode或Sublime Text打开文件:
打开替换视图Ctrl+H
确保启用选项Use regular expression。
粘贴正则表达式和替换字符串。
替换所有Ctrl+Alt+Enter

编辑:考虑多行反馈

^(d+).*n+)((?:*?[a-z]. .*n)*)(@ .*(?:n.*)*?n(?=[a-z].|nd+)|nn))((?:*?[a-z]. .*n)*)
