StringRegExpReplace wildcard issues

4 posts in this topic

Hi All,

I'm trying to use the StringRegExpReplace function to replace a randomly placed string "data ignore value = unknown numbers", in multiple *my.txt files with "new stuff". I have been able to get it to replace everything before the wildcard, but the numbers after the wildcard are tacked onto "new stuff"

So...

What I want to change in the text file:

data ignore value = 4
data ignore value = 45

What I want:

new stuff
new stuff

What I currently get:

new stuff 4

new stuff 45

$myfolder = @scriptdir
If $myfolder <> "" Then
   Local $hSearch = FileFindFirstFile($myfolder & "*my.txt")
   While 1
       $sFileName = FileFindNextFile($hSearch)
       If @error Then ExitLoop

$szFile = $sFileName
$szString = FileRead($szFile,FileGetSize($szFile))
$szString = StringRegExpReplace($szString, "data ignore value = *", "new stuff")
FileRecycle($szFile)
FileWrite($szFile,$szString)
   Wend
   FileClose($hSearch)
EndIf

Any help would be muchly appreciated.

Please use AutoIt tags (blue A) to show AutoIt code. As it's a little hard to read right now.

Change your:

$szString = StringRegExpReplace($szString, "data ignore value = *", "new stuff") 

to:

$szString = StringRegExpReplace($szString, "data ignore value =\s*\d+", "new stuff")

The asterisk in your version applies to the space before it, so your pattern will match any string that:

  • starts with data ignore value =
  • has 0 or more spaces behind that

My version should match any string that:

  • starts with data ignore value = (like yours)
  • has zero or more whitespace characters behind that string s* )
  • and has one or more digits behind those optional whitespaces ( d+ )

/edit note: untested.

Thanks SadBunny, those characters did the trick!
