有这么几百页这样的数据.

我需要这样的数据。以
do_pre开头，XLS结尾，
或者
recv_pre开头，.XLS结尾的为数据。
数据存储在.txt文件中.

比如
/prod/recv_pre/FGDYEI-4342407_ID.XLS
 /prod/recv_pre/FGDYEI-4342406_IH.XLS 
/prod/recv_pre/FGDYEI-4342406_ID.XLS 
/prod/recv_pre/FGDYEI-4342405_IH.XLS 
/prod/do_pre/FGDYEO-4342527_OD.XLS 
/prod/do_pre/FGDYEO-4342528_OH.XLS 
/prod/do_pre/FGDYEO-4342528_OD.XLS 
能再分类最好。比如
/recv_pre/
FGDYEI-4342968_IH.XLS  
FGDYEI-4342968_ID.XLS 
FGDYEI-4342967_IH.XLS 
/do_pre/
FGDYEO-4342974_OH.XLS 
   
do_pre/FGDYEO-4341596_OH.XLS 
或者
recv_pre/FGDYEI-4342968_IH.XLS
