StringRegExpReplace

6 posts in this topic

Hello,

I have text file with 9999 lines, for example text.txt, containing:

---start of file---
this is 0001. line with "some text string containing some number 25 and some number 63"
this is 0002. line with "some text string containing some number 14 and some number 55"
this is 0003. line with "some text string containing some number  7 and some number 13"
.
.
this is 9999. line with "some text string containing some number 39 and some number 15"
---end of file---

I would like to create new file with using FileRead, StringRegExpReplace and FileWrite:

---start of new file---
this is 0001. line with "some text string containing sum of both numbers 88"
this is 0002. line with "some text string containing sum of both numbers 69"
this is 0003. line with "some text string containing sum of both numbers 20"
.
.
this is 9999. line with "some text string containing sum of both numbers 54"
---end of new file---

pls. help me, thx.

Hi.

Welcome to the forum :graduated:

Rule #1: Post *YOUR* code when asking a question.

Here is my exception to this rule :(

#include <file.au3>

$File_in="C:\boot.ini"
$File_out="C:\Line-Numbers-added.txt"
$Content=""

_FileReadToArray($File_in,$Content)

for $i = 1 to $Content[0]
    $Pre="000" & $i
    $pre="This is line " & StringRight($pre,4) & ": "
    $Content[$i]=$pre & $Content[$i]
Next

_FileWriteFromArray($File_out,$Content,1)
run ("notepad.exe " & $file_out)

Regards, Rudi.

Local $sOut = "", $iVal
Local $sStr = "some text string containing some number 25 and some number 63" & @CRLF & "some text string containing some number 20 and some number 60"
Local $aStr = StringRegExp($sStr, "(?m:^|\n)\D*(\d+)\D*(\d+)\D*(?:\v|$)+", 3)
If NOT @Error Then
    For $i = 0 To UBound($aStr) -2 Step 2
        $iVal = $aStr[$i] + $aStr[$i +1]
        $sOut &= "The sum of " & $aStr[$i] & " + " & $aStr[$i+1] & " is " & $iVal & @CRLF
    Next
EndIf
MsgBox(0, "Test", $sOut)

Here is a different method in case there are lines with no numbers in them

Local $sOut = "", $iVal
Local $sStr = "Some text string containing some number 25 and some number 63" & @CRLF & "Some text string containing no numbers" & @CRLF
$sStr &= "Some text string containing some number 20 and some number 60"
Local $aStr = StringRegExp($sStr, "(?m:^|\n)(.+)(?:\v|$)+", 3)
If NOT @Error Then
    For $i = 0 To UBound($aStr) -1
        Local $iVal = Execute(StringRegExpReplace($aStr[$i], "(?m:^|\n)\D*(\d+)\D*(\d+)\D*(?:\v|$)+", '"$1" + "$2"'))
        If $iVal Then $sStr = StringReplace($sStr, $aStr[$i], "This line was replaced with the total " & $iVal)
    Next
EndIf
MsgBox(0, "Test", $sStr)

Try this.

Opt("WinTitleMatchMode", 2) ;1=start, 2=subStr, 3=exact, 4=advanced, -1 to -4=Nocase

; ======== Create & Display File =========
Local $sFile
If FileExists("TestNums.txt") = 0 Then
    For $i = 1 To 9999
        $sFile &= 'this is ' & StringRight("000" & $i, 4) & '. line with "some text string containing some number ' & _
                Random(1, 99, 1) & ' and some number ' & Random(1, 99, 1) & '"' & @CRLF
    Next
    FileWrite("TestNums.txt", StringTrimRight($sFile, 2))
EndIf

ShellExecute("TestNums.txt")
WinWaitActive("TestNums.txt")
Local $hWn = WinGetHandle("")
MsgBox(0, "", "Press OK to continue", 0, $hWn)


; ======== FileRead =========
Local $sFileOrig = FileRead("TestNums.txt")


; ======== StringRegExpReplace ======
Local $sFile2 = Execute(StringTrimRight(StringRegExpReplace($sFileOrig, "(?:[^\d]*)(\d+)(?:[^\d]*)(\d+)(?:[^\d]*)(\d+).*\v*", _
        '''this is \1. line with "some text string containing sum of both numbers '' & (\2 + \3) & ''"'' & @CRLF & '), 11))


; ======= FileWrite ==========
FileWrite("TestSum.txt", $sFile2)


; ====== Display & Delete the Created Files ========
ShellExecute("TestSum.txt")

WinWaitActive("TestSum.txt")
Local $hWn2 = WinGetHandle("TestSum.txt")
