regex - Notepad++ 组替换使用\k

Question

如何在 Notepad++ 中使用正则表达式将属于一组的所有项目放在一行中？

我有一组练习题答案，格式如下:

29  Continuous
29  Horizontal mattress
29  Interrupted
29  Vertical mattress
29  No use sutures because the immediate denture acts as a stint
30  1-5 years
30  6-10 years
30  11-15 years
30  16-20 years
30  21-25 years
31  Artery
32  Vitality of the tooth pulp
32  Age of the patient
32  Absence of root resorption

我希望对结果进行格式化，使每组都在一行上:

29 Continuous Horizontal mattress Vertical mattress No use sutures because the immediate denture acts as a stint
30 1-5 years 6-10 years 11-15 years 16-20 years 21-25 years
31 Artery
32 Vitality of the tooth pulp Age of the patient Absence of root resorption

我编写了以下正则表达式来选择集合:

^(?'number'^\d{0,4})\t(.*$)(\n\k<number>(.*))*

替换为 \1\2\4 给出

29 Continuous   No use sutures because the immediate denture acts as a stint
30 1-5 years    21-25 years
31 Artery 

我在这里做错了什么？

Answer 1

我制定了一个解决方案，以防有人尝试做类似的事情。

选择集合

(^(?'number'^\d{0,4})\t(.*$)(\n\k<number>(.*))*)

最初发布的代码之间的区别是整个代码周围的()

替换为 \1\n 以创建以下格式的集合:

29  Continuous
29  Horizontal mattress
29  Interrupted
29  Vertical mattress
29  No use sutures because the immediate denture acts as a stint

30  1-5 years
30  6-10 years
30  11-15 years
30  16-20 years
30  21-25 years

31  Artery

32  Vitality of the tooth pulp
32  Age of the patient
32  Absence of root resorption

用

选择单独的行

(^(?'number'^\d{0,4})\t(.*$))\n

替换为\3(\3后两个空格)创建

Continuous  Horizontal mattress  Interrupted  Vertical mattress  No use sutures because the immediate denture acts as a stint   
1-5 years  6-10 years  11-15 years  16-20 years  21-25 years    
Artery  
Vitality of the tooth pulp  Age of the patient  Absence of root resorption

我不知道如何使用正则表达式将问题 #s 添加回去，但如果需要，可以轻松地将其导入 excel 中以执行此操作。
