Extract number from string in batch file

Question

From a batch file I want to extract the number 653456 from the following string:

C:\\Users\\testing\\AppData\\Local\\Test\\abc123\\643456\\VSALB         


        

Answer 1

EDIT - Code sample adapted to correct errors shown in comments

set d=C:\Users\testing\AppData\Local\Test\abc123\643456\VSALBT81_COM
for %%f in ("%d:\=" "%") do for /f %%n in ('echo %%f^|findstr /b /e /r "\"[0-9]*\""') do (
    echo %%~n
)

Just precede the path with a quote, split the path, replacing each backslash with a quote a space and a quote and append a quote (so we have a list of elements to iterate), and for each part check if it is formed only by numbers
