SORT LINES

I have a text sorted like this:
1.xxxxxxx
3.xxxxxxx
2.xxxxxxx

if i join lines:
1.xxxxxxx3.xxxxxxx2.xxxxxxx

is there a command that that would rearrange or a sort command that would change line text to look like this:

1.xxxxxxx
2.xxxxxxx
3.xxxxxxx

Menu Edit / Sort lines will sort lines for you
If you want to separate long line into your short lines, use regular expressions

What is command for long line i used regex
(\d+)
\n$1
did not change?

FROM:
1.xxxxxxx3.xxxxxxx2.xxxxxxx

TO:
1.xxxxxxx
2.xxxxxxx
3.xxxxxxx

Use:
Find: (\d\D+)
Replace: $1\n
[X]RegEx
(o)Backward

For explanation see
en.wikipedia.org
