Question

Hello and excuse me again

I need a REGEX for delete the character space (” “). If this character is not followed for other space character.

Example String

"This  is  a  ex am ple" 

Result 

"This  is  a  example"

I was trying this REGEXES:

string.gsub(/\s{1}/,"")

Also I thought in submatches replace for I don´t know as use it in ruby

string.gsub(/(\w)( )(\w)/,/\1\3/)

However throw a exception.

Thanks in advance

Answer 1

You have small error in second gsub. Try this:

string.gsub(/(\w)( )(\w)/, '\1\3')

I checked this on your example, it works for me.
