我需要从文件中提取两个给定单词之间的文本.

I need to extract texts between two given words from a file.

some lines
<name>text1</name>
some lines
some lines 
<name>text2</name>

  谢谢.

  推荐答案

  以下脚本提取作为命令行参数提供的文件的所需标签之间的文本:

  The following script extracts the text in between the desired tags of the file(s) provided as command line argument(s):

  @echo off
  setlocal EnableExtensions DisableDelayedExpansion
  
  rem // Resolve command line arguments:
  for %%F in (%*) do (
      rem // Read a single line of text following certain criteria:
      for /F "delims=" %%L in ('
          findstr /R "^[^<>]*<name>[^<>][^<>]*</name>[^<>]*$" "%%~F"
      ') do (
          set "LINE=%%L"
          rem /* Extract the desired string portion;
          rem    the preceding `_` is inserted for the first token
          rem    never to appear empty to the `for /F` loop: */
          setlocal EnableDelayedExpansion
          for /F "tokens=3 delims=<>" %%K in ("_!LINE!") do (
              endlocal
              rem // Return found string portion:
              echo(%%K
          )
      )
  )
  
  endlocal
  exit /B
  

  这仅在只有一个标签<name>，然后是一些文本本身不包含<和>，然后是一个标签</name>的情况下才有效；该字符串必须在一行上，并且某些文本本身不能包含<和>.

  This works only if there is exactly one tag <name>, followed by some text not containing < and > on its own, followed by exactly one tag </name>; this string must be on a single line and may be preceded or followed by some texts not containing < and > on their own.
