批处理 - 获取两个字符串之间的内容

Question

我有这样的字符串

 <AdaptationSet maxHeight="576" maxWidth="1024" mimeType="video/mp4" id="0" segmentAlignment="true" startWithSAP="1">
  <ContentProtection schemeIdUri="urn:uuid:edef8ba9-79d6-4ace-a3c8-27dcd51d21ed" cenc:default_KID="bcf950eb-a062-5b0d-b1f2-fed53f20ba10">
    <cenc:pssh>AAAATHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAACwiJGFlNWU5NTk4LWU5ODktNWM1Ny1iOTk2LTg3OTA4NWIyYzUxNUjj3JWbBg==</cenc:pssh>
  </ContentProtection>
  <ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" cenc:default_KID="bcf950eb-a062-5b0d-b1f2-fed53f20ba10" />
  <SegmentTemplate duration="6000" initialization="$RepresentationID$/video/init.mp4" media="$RepresentationID$_184201/segment_$Number$.m4s" startNumber="0" timescale="1000" />
  <Representation bandwidth="247600" codecs="avc1.64001F" height="144" width="256" id="ae5e9598-e989-5c57-b996-879085b2c515-0_video_frag_auto.idx~video_frag_auto~481" scanType="progressive" />

我想像下面那样获得 output 并将其放入变量中。

ae5e9598-e989-5c57-b996-879085b2c515

请注意，第一行中已经有id="0" ，我想为最后一行部分提取 id 的值。 有没有一种简单的方法可以批量执行此操作？

Answer 1

如果您必须使用批处理，这里是一个开始的例子。 这将从包含您的字符串的文件 ooo.txt 中提取所有值 id。

@echo off
setlocal enabledelayedexpansion
set x=0
for /f "eol=> tokens=* usebackq delims= " %%i in (`type ooo.txt`) do (
  set x=0
  set XXX=XXX
  for %%I in (%%i) do (
    if "%%I"=="id" (
      set x=1
    ) else (
      if !x! EQU 1 (
        set x=0
        set XXX=%%I
      )
    )
  )
  set XXX=!XXX:"=!
  if not "!XXX!"=="XXX" (
    set XXX=!XXX:"=!
    rem echo !XXX!
    call :enumerate !XXX! YYY
    echo !YYY!
  )
)

goto :eof

:enumerate
set pos=0
set Y=%1
set result=
set part=
:countchar
if not "!Y:~%pos%,1!"=="" (
  set /a pos=pos+1
  if "!Y:~%pos%,1!"=="-" (
    set result=!result!!part!
    set part=
  )
  set part=!part!!Y:~%pos%,1!
  goto :countchar
)
set %~2=!result!
exit/b
:eof
endlocal

这输出

ae5e9598-e989-5c57-b996-879085b2c515

并且，在循环中，将每个 id 存储在变量YYY中（尽管第一个是空的）。

这假设您要保持所有内容都保持不变，但不包括最后一个连字符- 。

Answer 2

这是一个“有趣”的示例，由于您自己没有提供任何代码，因此不会在回答后修改，也不会提供任何支持或解释。

@For /F Delims^= %%G In ('%__AppDir__%findstr.exe /i "id=\"[a-e0123456789]*-[a-e0123456789]*-[a-e0123456789]*-[a-e0123456789]*-[a-e0123456789]*-" "xmlfile.mpd"'
) Do @Set "}=%%G" & SetLocal EnableDelayedExpansion & For /F UseBackTokens^=2-6Delims^=-^" %%H In ('!}:* id^=^"^=!') Do @Endlocal & Set "id=%%H-%%I-%%J-%%K-%%L"
@(Set id) 2>NUL & Pause

您可能希望从xmlfile.mpd更改源文件名，并且可以选择删除最后一行，它只是为了让您查看它是否有效而包含在内！

Answer 3

@ECHO OFF
SETLOCAL
rem The following settings for the source directory, destination directory, target directory,
rem batch directory, filenames, output filename and temporary filename [if shown] are names
rem that I use for testing and deliberately include names which include spaces to make sure
rem that the process works using such names. These will need to be changed to suit your situation.

SET "sourcedir=u:\your files"
SET "filename1=%sourcedir%\q65892027.txt"

SET "capture="
SET "captured="

FOR /f "usebackqdelims=" %%b IN ("%filename1%") DO (
 FOR %%c IN (%%b) DO (
  IF /i "%%~c"=="scantype" SET "capture="&IF DEFINED captured GOTO done
  IF DEFINED capture SET "captured=%%~c"
  IF /i "%%~c"=="id" SET "capture=Y"
 )
)
:done
ECHO captured "%captured%"
GOTO :EOF
