【已解决】【50元红包】指定路径所有子文件夹里xml文件修改参数替换

本帖最后由 linfeng_321 于 2022-5-9 12:09 编辑

需求:指定路径所有子文件夹里xml文件修改参数替换

1、persist  改成 const
2、persist="true"  改成 const="true"
3、我可以设置更多参数,进行xml文件里所有对应参数替换

  1. <#*,:&cls
  2. @echo off
  3. cd /d "%~dp0"
  4. powershell -C "Set-Location -LiteralPath ([Environment]::CurrentDirectory);. ([ScriptBlock]::Create((Get-Content -LiteralPath \"%~f0\" -ReadCount 0 | Out-String)))"
  5. pause
  6. exit /b
  7. #>
  8. # 替换字符串
  9. $htstr = @{
  10.   'persist'        = 'const'
  11.   'persist="true"' = 'const="true"'
  12. }
  13. # xml路径
  14. $xmlPath = ".\xml\*.xml"
