问题描述

Since this weekend I'm stuck on a REGEX expression which must be simple I guess... Could you help me on the definition of the expression, please?由于这个周末我被困在一个 REGEX 表达式上，我想这一定很简单......你能帮我解释一下表达式的定义吗？

In the links below , I would simply like to catch the height="25"> only when two "height="25"> follow each other and find and replace it:在下面的链接中，我只想在两个“height="25">相互跟随并找到并替换它时捕获height="25"> ：

https://regex101.com/r/Ly742Z/1 https://regex101.com/r/Ly742Z/1

I had thought of the following logic:我想到了以下逻辑：

  • If you find 2 "height="25"> on two consecutive strings (see below):如果您在两个连续的字符串上找到 2 "height="25"> （见下文）：
  • Then grab the 2nd " height="25"然后抓住第二个“ height="25"

It gave me this for now: (" height="25">. \n). (?<=" height="25">)它现在给了我这个：(" height="25">。 \n)。 (?<=" height="25">)

What do you think about it?你怎么看待这件事？

Thanks!谢谢！

You can use this regex:您可以使用此正则表达式：

(" height="(.*)">.*\n)" height="\2">

Group 1 capture the first line第 1 组捕获第一行

Group 2 capture the height value第 2 组捕获高度值
