查找并替换emacs中的周围单词

Question

请考虑以下事项：

The cat jumped over the wall
The cat sat on the wall
The cat strolled along the wall
The cat hid under the hedge
The horse considered the wall

我想在emacs中用“dog * bridge”替换“cat * wall”，结果是：

The dog jumped over the bridge
The dog sat on the bridge
The dog strolled along the bridge
The cat hid under the hedge
The horse considered the wall

我知道我可以找到替换只是猫 - ＆gt;狗并接受每个例子，但我想知道如何自动完成所有这些

Answer 1

谢谢@Barmar

我正在寻找的正则表达式是

cat \(.*\) wall -> dog \1 bridge
