Notepad++ 正则表达式匹配和替换某些标签之间的第一个逗号

Question

I have data like so opened in Notepad++:

<title>Name 1, Address 1, NY</address>
<title>Name 2, Address 2, California</address>
<title>Name 3, Address 3, Texas</address>
<title>Name 4</title> <address>Address 4, Utah</address> <-- this line is 100% correct

...and I would llike to target the first comma on the groups that need proper tag enclosing, and replace it by: </title><address>

I did this and it targets the second group (address), but the replace regex I don't know what to use to keep the integrity of the address data, I tried something like this but it destroys the whole address:

• Find What: , (.+address)
• Replace with: </title><address>(.+address)

How to simply replace the first comma by new tags </title><address> ?

Answer 1

You can use

<title>[^<>,\v]*\K,\h*([^<>\v]*</address>)

Replace with </title> <address>\1 .

See the regex demo .

Details

• <title> - a string <title>
• [^<>,\v]* - zero or more chars other than < , > , comma and any vertical whitespace
• \K - match reset operator that disacards all text matched so far
• , - a comma
• \h* - zero or more horizontal whitespaces
• ([^<>\v]*</address>) - Group 1 (the $1 or \1 backreference refers to the group value):
  • [^<>\v]* - zero or more chars other than < , > and any vertical whitespace
  • </address> - a </address> string.
