I need to parse a text file so the results only show like the following:

The data.txt file I'm parsing from:

D08-10-06 10:05:27.010 XXX:390823892aw4dca: -rate(Dlr/u):15.792581 for ASDGADFSCSS:[TRUCKS->TRAILERS]
D08-10-06 10:07:28.593 XXX:390823892aw4dca: -rate(Dlr/u):94.99838 for ASDRFACSD:[TRAILERS->AIRPLANE]

Results Requested:

DLR,Rate,Method
Dlr/u,15,TRUCKS->TRAILERS
Dlr/u,94,TRAILERS->AIRPLANE

I would like to use either FindStr or some DOS method, or vbscript to parse the file. I have writen one but doesn't quite do the job.
Option Explicit 
 
Dim objFSO, objLog 
Dim strInputLog, strOutputLog, strData, strLine, strMethod, strTime 
Dim strDetail, strDlr 
Dim arrLines, arrDetail 
Dim intLength 
Dim strFnl
 
CONST ForReading = 1 
 
Set objFSO = CreateObject("Scripting.FileSystemObject") 
 
'Set path to input and output files 
strInputLog = "data.txt" 
strOutputLog = "Final_data.txt" 
 
'Open input log and create the output log 
strData = objFSO.OpenTextFile(strInputLog,ForReading).ReadAll 
Set objLog = objFSO.CreateTextFile(strOutputLog) 
 
'Split the input log into lines 
arrLines = Split(strData,vbCrLf) 
 
'Step through the input log lines and break them into 
'strings based on spaces 
For Each strLine in arrLines 
If strLine <> "" Then 
arrDetail = Split(strLine," ") 
 
'Parse through strings looking for matches, process the 
'strings and write results to output log 
For Each strDetail in arrDetail 
  intLength = LEN(strDetail) 
  If InStr(strDetail,"TRUCKS->TRAILERS") Then 
   strMethod = Right(strDetail,intLength - 78) 
ElseIf InStr(strDetail,"TRAILERS->AIRPLANE") Then 
   strMethod = Right(strDetail,intLength - 78) 
ElseIf InStr(strDetail,"TRAILERS->ROCKET") Then 
   strMethod = Right(strDetail,intLength - 78)
  ElseIf InStr(strDetail,"Dlr/u,") Then 
   strDlr = Right(strDetail,intLength - 5) 
 
strMethod = Replace(strMethod, ":", ",")
strMethod = Replace(strMethod, "[", ",")
strMethod = Replace(strMethod, "]", "")
strDlr = Replace(strDlr, ":", ",")
strDlr = Replace(strDlr, ".", ",")
strDlr = Replace(strDlr, "(", "")
strDlr = Replace(strDlr, ")", "")
 
 
 
 
 
strFnl = strDlr & "" & strMethod & "," & Date
 
strFnl = Replace(strFnl, "),,", ",")
strFnl = Replace(strFnl, ",,", ",")
 
objLog.Writeline strFnl
 
 
 
  End If 
Next

Try this out...

'Open input log and create the output log

Set objLog = objFSO.CreateTextFile(strOutputLog) 
 
'Split the input log into lines

' Sample Input Line:

I didn't put the column headers into the output file...  =\

Add this line:

    objLog.Writeline "DLR, Rate, Method"

Right above the "For Each" loop.

If you want a space after the comma in the data lines then change:

    objLog.Writeline Join(Array(DLR, Rate, Method), ",")

To:

    objLog.Writeline Join(Array(DLR, Rate, Method), ", ") ' <--- Space after the comma!

Thank you Idle_mind however I kept getting errors when trying to use your script. I ended up coming up with this script instead.

Const ForReading = 1

strInputLog = "data.txt"
strOutputLog = "Final_data.txt"
strSearchString1 = "dlr/"
strSearchString2 = ":["

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objInputFile = objFSO.OpenTextFile(strInputLog, ForReading)

Set objOutputFile = objFSO.CreateTextFile(strOutputLog)

Do Until objInputFile.AtEndOfStream
    strText = objInputFile.ReadLine

    strFoundString1 = Mid(strText, InStr(1, strText, strSearchString1) + 7)
    strFoundString1 = Mid(strFoundString1, 1, InStr(1, strFoundString1, " ") - 1)
   
    strFoundString2 = Mid(strText, InStr(1, strText, strSearchString2) + 2)
    strFoundString2 = Mid(strFoundString2, 1, InStr(1, strFoundString2, "]") - 1)
   
    objOutputFile.WriteLine (strFoundString1 & "," & strFoundString2 & "," & date)
Loop

objInputFile.Close
objOutputFile.Close

Set objInputFile = Nothing
Set objOutputFile = Nothing

Set objFSO = Nothing
