Recycle all app pools with a .bat file with a delay between each one

I would like to have a delay between each recycled app pool so the CPU doesn't get high. Below is my current .bat file that recycles all my app pools at once. How can I add a delay between each one before the other gets executed?

%windir%\system32\inetsrv\appcmd list wp /xml | %windir%\system32\inetsrv\appcmd recycle apppool /in

Here is my output per a answer

<?xml version="1.0" encoding="UTF-8"?>

<appcmd>

    <WP WP.NAME="8476" APPPOOL.NAME="8476.com" />

    <WP WP.NAME="11636" APPPOOL.NAME="11636.com" />

    <WP WP.NAME="8868" APPPOOL.NAME="8868.com" />

    <WP WP.NAME="6180" APPPOOL.NAME="6180.com" />

    <WP WP.NAME="5636" APPPOOL.NAME="5636.com" />

    <WP WP.NAME="12616" APPPOOL.NAME="12616.com" />

    <WP WP.NAME="7472" APPPOOL.NAME="7472.com" />

    <WP WP.NAME="1668" APPPOOL.NAME="1668.com" />

    <WP WP.NAME="9608" APPPOOL.NAME="9608.com" />

    <WP WP.NAME="12480" APPPOOL.NAME="12480.com" />

</appcmd>

EDIT 2022/08/04: New code based on new posted data

The appcmd list wp /xml command outputs one XML file that contains several WP sections, one for each app pool, in this format:

<?xml version="1.0" encoding="UTF-8"?>

<appcmd>

    <WP data for pool 1 />

    <WP data for pool 2 />

    . . .

</appcmd>

In this way, in order to execute each app pool cmd individually, we need to create individual well-formatted XML files. The Batch file below do so:

@echo off
setlocal DisableDelayedExpansion

rem Create the "all apps" XML output file
%windir%\system32\inetsrv\appcmd.exe list wp /xml > appcmdXMLout.txt

rem Separate "all apps" output file into individual app input file(s) and process each
set "header="
set "line1="
for /F "delims=" %%a in (appcmdXMLout.txt) do (

   if not defined header (
      set "header=%%a"
      setlocal EnableDelayedExpansion
      > appcmdXMLin.txt echo !header!
      endlocal
   ) else if not defined line1 (
      set "line1=%%a"
      setlocal EnableDelayedExpansion
      >> appcmdXMLin.txt echo !line1!
      endlocal
   ) else if "%%a" neq "</appcmd>" (
      rem One appcmd completed: process it
      (
      set /P "=%%a" < NUL
      echo/
      echo ^</appcmd^>
      ) >> appcmdXMLin.txt

      %windir%\system32\inetsrv\appcmd.exe recycle apppool /in < appcmdXMLin.txt
      timeout /T 5 > NUL

      setlocal EnableDelayedExpansion
      (
      echo !header!
      echo !line1!
      ) > appcmdXMLin.txt
      endlocal

   )

)

del appcmdXMLout.txt appcmdXMLin.txt

[Theoretical]

for /f "delims=" %%b in ('%windir%\system32\inetsrv\appcmd list wp /xml') do echo %%b|%windir%\system32\inetsrv\appcmd recycle apppool /in&timeout /t 3 >nul

I'm assuming that this is in a batch file. If running from the prompt, change each %%b to %b.

The >nul suppresses timeout's countdown. The 3 means 3 seconds and the space between 3 and > is required.

%%b should be set to each line appearing from the single-quoted command, and then gets echoed to the recycling app, followed by a delay of (an integral number) of seconds.
