Question

使用下面的正则表达式，我得到单个XML元素“lesson”。

(.*?)<lesson id=(.*)[\s\S]*?<\/lesson>

但是如何搜索具有特定内容的XML元素并在Notepad ++中标记整个XML元素“课程”，由此我可以将XML元素复制到另一个文件中。

使用以下内容查找并标记XML元素“课程”：

<assigned_day>5</assigned_day>

XML示例

<lesson id="LS_18300">
  <periods>2</periods>

一次尝试是这样的：

(.*?)<lesson id=(.*)[\s\S]*?(assigned_day>5)?<\/lesson>

Answer 1

你可以试试这个正则表达式：

<lesson\s+id[^>]*>(?=(?:(?!<\/lesson>).)*<assigned_day>5<\/assigned_day>).*?<\/lesson>

p.s：确保在记事本++编辑器中检查._matches换行符
