正则表达式查找小写字母后跟大写字母
我很难在 TextWrangler 中使用正则表达式 (Grep) 来查找小写字母后跟大写的出现情况。例如：
此公告表示欢迎学生。
事实上，我想通过添加冒号来分割出现，使其成为意思：学生
我已经尝试过：
[a-z][A-Z]
但是这个表达式在TextWrangler中不起作用。
*编辑：这里是出现的确切上下文（我的意思是仅使用这些字体颜色）。*
<font color =#48B700> - Stột jlăm wẻ baOne hundred and three<br></font>
<font color =#C0C0C0> »» Qzống pguộc lyời ba yghìm fảy dyổiTo live a life full of vicissitudes, to live a life marked by ups and downs<br></font>
"baOne" and "dyổiTo" must be "ba: One" and "dyổi: To"
有人可以帮忙吗？非常感谢。
I have difficulty using Regular Expression (Grep) in TextWrangler to find occurrences of lowercase letter followed by uppercase. For example:
This announcement meansStudents are welcome.
In fact, I want to split the occurrence by adding a colon so that it becomes means: Students
I have tried:
[a-z][A-Z]
But this expression does not work in TextWrangler.
*EDIT: here are the exact contexts in which the occurrences appear (I mean only with these font colors).*
<font color =#48B700> - Stột jlăm wẻ baOne hundred and three<br></font>
<font color =#C0C0C0> »» Qzống pguộc lyời ba yghìm fảy dyổiTo live a life full of vicissitudes, to live a life marked by ups and downs<br></font>
"baOne" and "dyổiTo" must be "ba: One" and "dyổi: To"
Could anyone help? Many thanks.

这是识别小写和大写字母的正确模式，但是，您需要在查找/替换对话框中检查匹配是否区分大小写。
That is the correct pattern for identifying lower case and upper case letters, however, you will need to check matching to be Case Sensitive within the Find/Replace dialogue.
我确实相信（虽然手头没有 TextWrangler）您需要搜索
([az])([AZ])并将其替换为：\1: \2< /code>希望这有帮助。
I do believe (don't have TextWrangler at hand though) that you need to search for
([a-z])([A-Z])and replace it with:\1: \2Hope this helps.
将
([az])([AZ])替换为\1:\2- 我没有 TextWrangler，但它可以在 Notepad++ 上使用括号用于捕获data，在替换字符串中使用
\1语法引用Replace
([a-z])([A-Z])with\1:\2- I don't have TextWrangler, but it works on Notepad++The parenthesis are for capturing the data, which is referred to using
\1syntax in the replacement string这个问题由来已久，但我偶然发现了它，所以其他人也可能会这样做。 OP 对 Igor 回复的评论 澄清了如何描述任务（并且可以添加到描述中）。
要仅匹配 HTML 中那些特定于字体的行，请替换
(?<=)(.*?[az])([AZ])< /code>和
\1: \2说明：
(?<=[固定长度正则表达式])是一个 正向回顾 表示“如果我的匹配项前面有这个” >(?:48B700|C0C0C0)是一个未命名的组，仅匹配 2 种颜色。由于它们具有相同的长度，因此它们在后向工作（需要具有固定长度）(.*?[az])([AZ])将匹配之后的所有内容>开始的字体标签一直到大写字母。\1: \2替换与 Igor 的响应中的相同，只是\1将匹配需要分隔的整个第一个字符串。添加：
您的输入字符串包含特殊字符，并且您想要拆分的部分很可能以 1 结尾。在这种情况下，它们不会被
[az]单独捕获。您需要添加一个字符游标来捕获您关心的所有字母，例如(?<=<字体颜色=#(?:48B700|C0C0C0)>)(.*?[a-zḁ-ῼ])([AZ])This question is ages old, but I stumbled upon it, so someone else might, as well. The OP's comment to Igor's response clarified how the task was meant to be described (& could have be added to the description).
To match only those font-specific lines of the HTML replace
(?<=<font color =#(?:48B700|C0C0C0)>)(.*?[a-z])([A-Z])with
\1: \2Explanation:
(?<=[fixed-length regex])is a positive lookbehind and means "if my match has this just before it"(?:48B700|C0C0C0)is an unnamed group to match only 2 colours. Since they are of the same length, they work in a lookbehind (that needs to be of fixed length)(.*?[a-z])([A-Z])will match everything after the>of those begin font tags up to your Capital letters.\1: \2replacement is the same as in Igor's response, only that\1will match the entire first string that needs separating.Addition:
Your input strings contain special characters and the part you want to split may very well end in one. In this case they won't be caught by
[a-z]alone. You will need to add a character ranger that captures all the letters you care about, something like(?<=<font color =#(?:48B700|C0C0C0)>)(.*?[a-zḁ-ῼ])([A-Z])
