[文本处理] 如何提取两个字符之间的数值然后显示最小数值

比如有一a.txt内容为:
fdsaf k456l dsad
ewqeqw k123l dsd
ewqewq　k111l dsad
我要显示k与l之间数值的最小植（１１１）

@echo off&setlocal enabledelayedexpansion
for /f "tokens=2 delims=　 " %%a in (a.txt) do (
     set "var=%%a"
     if "!var:~1,-1!" leq "!str:~1,-1!" set "x=!var:~1,-1!"
     set "str=%%a"
)
echo %x%
pause
