A bit more simplistic than Tim's but here's a basic idea:

Match on a < before a >, or:
Match on no following >

<a[^><]+((?=<)|(?!.*>))

In substitution it breaks the last div of 1. 1. cipe at /div> – AMit SiNgh Mar 23 '21 at 06:00
@AMitSiNgh hm? Add `?:` to the group to make it a non-grouping class – David542 Mar 23 '21 at 06:02
`<]+((?=<)|(?!.*>))` ? – David542 Mar 23 '21 at 06:13
Can you please explaint this part. (?!.*>) why we put .* here – AMit SiNgh Mar 23 '21 at 07:29
@AMitSiNgh `.*` would mean one of more of anything -- `.` (dot) matches all. So doing `(?!)` is a negative lookahead to make sure that `` does not occur at the position after the current cursor location, and putting the `.*` before the makes sure that `` never occurs at all. Note that `.` in the above case does not include newline (but it can depending on the regex settings). – David542 Mar 26 '21 at 19:21
