Extract list of path in a file using batch script - windows

Question

Here is my text file:
==================================================
Folder : D:\T\New folder
==================================================
==================================================
Folder : D:\T\Z-Ai
==================================================
==================================================
Folder : D:\T\Z-BiN
==================================================
I need to extract the paths from this file, so I have something like this:
D:\T\New folder
D:\T\Z-Ai
D:\T\Z-BiN
It seems I should use findstr TargetWord TargetFile.txt command. and Also it seems I can use regex like this: findstr /r "^[a-z][a-z]$ ^[a-z][a-z][a-z]$"
But I do not know how to loop through found targets or get the list of output. any help is really appreciated.

Answer 1

Based on your comment, you want to use the result to perform an xcopy task, it seems you really want something like this. Note I used example.txt as input file, and DESTINATION where you should add your destination, including the relevant xcopy switches you require:
#echo off
for /f "tokens=2*" %%i in ('type example.txt ^| findstr /i ":\\"') do xcopy "%%~j\*" DESTINATION
Alternatively we can use the findstr directly on Folder
#echo off
for /f "tokens=2*" %%i in ('type example.txt ^| findstr /i "Folder"') do xcopy "%%~j\*" DESTINATION

You can do like this :
#echo off
Title Extract list of path in a file using batch script
set "TxtList=MyList.txt"
Set "OutPutData=Output.txt"
Call :Extract "%TxtList%" "%OutPutData%"
Start "" "%OutPutData%"
Exit

:Extract <InputData> <OutPutData>

echo Data = Extract(Data,"[\w]:(\\[0-9\sA-Za-z\-]*)+"^)
echo WScript.StdOut.WriteLine Data

echo set oRE = New RegExp
echo oRE.IgnoreCase = True
echo oRE.Global = True

echo set oMatches = oRE.Execute(Data^)
echo If not isEmpty(oMatches^) then
echo For Each Match in oMatches
echo Line = Line ^& Trim(Match.Value^) ^& vbcrlf
echo Next
echo Extract = Line
echo End if
echo End Function
echo '************************************************
)>"%tmp%\%~n0.vbs"
cscript /nologo "%tmp%\%~n0.vbs" < "%~1" > "%~2"
If Exist "%tmp%\%~n0.vbs" Del "%tmp%\%~n0.vbs"
exit /b

For Windows. you can use powershell.
select-string -Path c:\tmp\file.txt -Pattern '[A-Z]:(\\[0-9\ A-Za-z\-]*)+' -AllMatches | % { $_.Matches } | % { $_.Value }

Answer 4

In my opinion, For /F is all you need for the task. Although using Type may be useful in some situations, there's no need to use find.exe or findstr.exe for this task as you don't need to match a particular glob/pattern:
#For /F "EOL==Tokens=2*UseBackQ" %%A In ("TargetFile.txt")Do #"%__AppDir__%xcopy.exe" "%%B" "Destination\" /Options
Please note that it may be wise, if there's a chance that one or more of theses Folders do not exist, that you prepend using If Exist "%%B\". Importantly, if each of the lines containing the Folder paths, is space padded up to the end of its line, this solution will not work for you.
