ah, sorry, I try to make this more clear again:

(DrDocument is instance of a styled text control)

import re
import string

def GetEndOfLineCharacter():
    emode = DrDocument.GetEOLMode()
    if emode == wx.stc.STC_EOL_CR:
      return '\r'
    elif emode == wx.stc.STC_EOL_CRLF:
      return '\r\n'
    return '\n'

text = DrDocument.GetText()

eol = GetEndOfLineCharacter()
regex = re.compile('\s+' + eol, re.MULTILINE)

lines = text.split(eol)
    
new_lines = []
for line in lines:
  result = regex.search(line + eol)
  if result != None:
    end = result.start()
    new_lines.append (line [:end])
  else:
    new_lines.append(line)
    
    
newtext = string.join(new_lines, eol)
DrDocument.SetText(newtext)
