StripWS from file

[VAADAdmin]

Below is my function that I am trying to write. I am doing something wrong and I don't know what. At the bottom I have the file which I want to alter. The script below will remove the white space within a line, but how do I get rid of the blank lines in between. I have tried stringreplace as well. I must be missing something simple I assume. Part two is the lines in the file could be fine but when I pull the arraytostring from my _stringbetween, it will bring back the blank lines which I do not understand either since I am pulling the items between the [] into an array. Any help would be greatly appreciated.

Had you tried (Example only, you'll need to implement):

$sString = StringReplace($sString, @CR, '')
$sString = StringReplace($sString, @LF, '')
MsgBox(64, 'No Line Feeds', $sString)

not understand either since I am pulling the items between the [] into an array. Any help would be greatly appreciated.

Something like this?

#include <array.au3>
#include <File.au3>

Dim $lines

$filename = "c:\temp\au3\40530.txt"
_FileReadToArray($filename,$lines)
_ArrayDisplay($lines,"File")

Dim $newlines[1]

$n = 0
for $i =  1 to $lines[0]
    $lines[$i] = StringStripWS($lines[$i],8)
    if (StringLen($lines[$i])) then
        $n = $n + 1
        _ArrayAdd($newlines,$lines[$i])
    endif
next

$newlines[0] = $n
_ArrayDisplay($newlines,"File")

_FileWriteFromArray($filename & ".new", $newlines,1)
