Question

I have a simple piece of script (which uses RegEx) which cleans up a source string to leave only alpha-numeric-and-whitespace characters.

Sometimes, I end up with a number of whitespace characters next to each other.

eg.

source: abc def ghi 
result: abc def ghi

source: a*bc D*f
result: abc df

source: a*bc *** def
result: abc  def  <-- notice the two spaces in there
expected result: abc def  <-- notice one space, here.

So i was hoping some regex could look for 2+ spaces next to each other, in some source string and replace it with a single whitespace character.

cheers 🙂

Answer 1

Just use \s\s+ as the string to match, and a single space as the replacement.
