我测试了以上代码，似乎都未符合题意，试试这个

@echo off
setlocal enabledelayedexpansion

set num=0
set result=
set tmpstr=
set "str=f.h5h,h87h非fh好46hs 7df，asf8,hsf dh;58gh7.6sh4批:处理s86h7shh7gh8jiagn"
echo 字符串:%str%

for /l %%i in (0,1,255) do (
  set tmpstr=!str:~%%i,1!
  if "!tmpstr!"=="" goto end
  if !tmpstr! leq 9 if !tmpstr! geq 0 set result=!result!!tmpstr!&& set /a num+=1
)

:end
echo 数字子串:  !result!
echo 数字个数:  !num!
