What regex to use for this

Question

I\'m writing a regex that will find either

• 1 or more dots . .. ... .... followed by a space or not followe

Answer 1

• To match one or more . characters followed by a space: /\.+ /
• To match one or more . characters followed by nothing: /\.+$/
• To match one or more ? characters followed by a space: /\?+ /
• To match one or more ? characters followed by nothing: /\?+$/

To match any of these patterns: /\.+ |\.+$|\?+ |\?+$/

Answer 2

If you want to group each section...

(\.+|\?+)( ?)(.+)

Answer 3

For the dots, you can use the + thing, which specifies one or more occurrences of the preceding string. Also, you'd have to escape the . and the ?, as they have special meanings in regex:

(\.+)$
(\?+)$

Answer 4

\.+ ?$
\?+ ?$

(you just need to escape a . or ? with a \ to match it literally, since those characters have special meanings in regular expressions.)

Prefix either of these with ^ if you want to match lines containing only your pattern.

Answer 5

If you need both in the same regex:

(\.+|\?+)

Or separate:

(\.+)

(\?+)

And this answer needs to be 30 characters long to submit...

Answer 6

You'd do something like the following

(\.+|\?+)\s*
