批處理 - 獲取兩個字符串之間的內容

Question

我有這樣的字符串

 <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" />

我想像下面那樣獲得 output 並將其放入變量中。

ae5e9598-e989-5c57-b996-879085b2c515

請注意，第一行中已經有id="0" ，我想為最后一行部分提取 id 的值。 有沒有一種簡單的方法可以批量執行此操作？

Answer 1

如果您必須使用批處理，這里是一個開始的例子。 這將從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

這輸出

ae5e9598-e989-5c57-b996-879085b2c515

並且，在循環中，將每個 id 存儲在變量YYY中（盡管第一個是空的）。

這假設您要保持所有內容都保持不變，但不包括最后一個連字符- 。

Answer 2

這是一個“有趣”的示例，由於您自己沒有提供任何代碼，因此不會在回答后修改，也不會提供任何支持或解釋。

@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

您可能希望從xmlfile.mpd更改源文件名，並且可以選擇刪除最后一行，它只是為了讓您查看它是否有效而包含在內！

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
