比如文本文件1.txt内容如下
U Percentage       =    47.310368633
V Percentage       =    13.429474740

Point on Face       XC = -7.206359227       X = -7.206359227
                  YC = 0.207949979       Y = 0.207949979
                  ZC = 21.642631315       Z = 21.642631315
U First Derivative XC = 14.155746145       X = 14.155746145
                  YC =  -82.965589343       Y =  -82.965589343
                  ZC = 0.000000000       Z = 0.000000000

V First Derivative XC = 0.000000000       X = 0.000000000
                  YC = 0.000000000       Y = 0.000000000
                  ZC =  -25.000000000       Z =  -25.000000000

Unit Face Normal    XC = 0.985754378       X = 0.985754378
                  YC = 0.168191281       Y = 0.168191281
                  ZC = 0.000000000       Z = 0.000000000

Principal Radii of Curvature
Minimum             =    -13.395206706
Maximum             = Infinite

U Percentage       =    45.290722375
V Percentage       =    84.025423921

Point on Face       XC = -7.597661914       X = -7.597661914
                  YC = 1.860952417       Y = 1.860952417
                  ZC = 3.993644020       Z = 3.993644020

U First Derivative XC = 24.541866779       X = 24.541866779
                  YC =  -80.506962053       Y =  -80.506962053
                  ZC = 0.000000000       Z = 0.000000000

V First Derivative XC = 0.000000000       X = 0.000000000
                  YC = 0.000000000       Y = 0.000000000
                  ZC =  -25.000000000       Z =  -25.000000000

                  YC = 0.291593814       Y = 0.291593814
                  ZC = 0.000000000       Z = 0.000000000

Principal Radii of Curvature

我想提取Point on Face后XC，YC，ZC，unit Face Normal X,Y,Z值，保留小数点4位，并输出到新的文本文件2.txt中格式如下
1 -7.2063 0.2079  21.6426 0.9857 0.1681  0.0000
2 -7.5976  1.8609 3.9936    0.9565 0.2915  0.0000
请高手指点怎么写批处理，

有点麻烦：

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%a in (1.txt) do (
    for /f "tokens=1" %%b in ("%%a") do (
        for %%c in (Point Unit) do if "%%b" equ "%%c" set "flag=a"
        if defined flag (
           for /f "tokens=2,3 delims==" %%b in ("%%a") do (
               set /a n+=1
               if !n! leq 3 (
                  set "a=%%b"&set "b=%%c"
                  for %%a in (a b) do (
                      for /f "tokens=1,2 delims=." %%b in ("!%%a!") do set "xs=%%c"&set "_%%a=!_%%a! %%b.!xs:~,4!"
                  )
                  ) else (
                  set "flag="&set /a n=0
               )  
            )
         )
     )
)
(for %%a in (a b) do echo !_%%a:~1!)>2.txt
start 2.txt
