上面是电脑的PCI插槽的硬件ID，我要从这堆文字中得到网卡的ID里在\与&之间区别于其他ID的字符串，比如我这里的话就是：PCI\VEN_8086&DEV_100F&SUBSYS_075015AD&REV_01\4&3AD87E0A&0&0888: Intel(R) PRO/1000 MT Network Connection中的红色部分，
用批处理将其帅选出来

假设文本文件为a.txt
@echo offsetlocalfor /f "tokens=2 delims=&" %%a in (a.txt) do ( if not defined %%a ( set %%a=1 echo %%a ) )endlocalpause
