Question

您好我想创建一个正则表达式来查找在它们之间有大写单词的单词。谁能告诉我如何找到它？

例如：I went to a school forEducation and then didn't study.

我想要像forEducation这样的词。我想我们使用[a-z][A-Z]来查找所有字母但却找不到它。我正在考虑合并上述两个选项，但那么如何检查大写字母？此外，我不想选择任何在开头有大写字母的单词，因为它们是有效的。

原因：这是因为从在线网站抓取文字并且没有正确的格式。我把这些单词作为文本，并想要替换它们。

Answer 1

[a-zA-Z][a-z]*[A-Z][a-zA-Z]*

以任何字母开头，后跟0或更多小写字母，后跟大写字母，后跟0或更多字母（大写或不大写）

Answer 2

如果我猜对了，你想要拆分camelCased的单词，对吧？

然后使用

ResultString = Regex.Replace(SubjectString, 
    "(?<=\p{Ll})  # Assert that the previous character is a lowercase letter" & chr(10) & _
    "(?=\p{Lu})   # Assert that the next character is an uppercase letter", 
    " ", RegexOptions.IgnorePatternWhitespace)

此更改

I went to a school forEducation and then didn't study.

到

I went to a school for Education and then didn't study.
