[SOLVED] Regex to find double whitespace not on the start of a line

Regex to find double whitespace not on the start of a line

I'm struggling with old "formatted" code, where a lot of whitespace is added to line up ='s and so on:

  if (!This.RevData.Last().Size() eq 0) then
    !DocRev   = '?'
    !Status   = '?'
    !RevCode  = '?'
  else
    !Pad      = !This.RevData.Last()[1]
    !DocRev   = !Pad[2]
    !Status   = !This.GenUtil.If((!Pad[3] eq 'UA'), '' , !Pad[3])
    !RevCode  = !This.GenUtil.If((!Pad[6] eq ''  ), '?', !Pad[6])
  endif

In this example it actually makes some sense, but most often the code have been modified to a state that makes the whitespace much more confusing than helpful.

What I'd like to do is to replace all double (or more) whitespaces with a single space, but I'd of course like to keep the indenting. Hence I'm looking for a regex to identify double (or more) spaces that are not at the start of the line. I've tried negative lookbehind, but can't seem to make it work:

(?<![\n])[\s]{2,}

Any hints, anyone? Ohh, and I'm using Ultraedit (the Perl regex engine), so the regex should be "UE-compatible".

EDIT: UE doesn't evaluate regex's line for line; newlines is just a character in the long string that is the document, which complicates the problem a bit.

Solution

Replace "([^ \n] ) +" with "$1". No funky lookbehinds required.
