It is hard to tell from your question exactly what you need. Something that will help you in general is to learn more about how to use RegEx. A very helpful site is regexlib [^]they have a large library of Regular Expressions. They also have a RegEx tester[^] which is very helpful in testing your RegEx code.

这里提供了一个答案：复制父项的所有节点并将其附加到父节点用每个副本替换属性 [ ^ ]

An answer has been provided here: Copy all nodes of a parent and append it in the parent node replacing the attribute with each copy[^]

您显示的模糊示例与RefEx代码和保存代码与上述内容无关。

请记住，我们不在您的脑海中，我们看不到您的屏幕。

提出问题是一种技巧 [ ^ ]

You show a vague example which do not match the RefEx code and the save code is unlinked to the above.
