[文本处理] 请教怎么样把特定文本中的特定内容用echo输出？

文件存在C盘，名称是test.log，我想在批处理中读出<ProductKey></ProductKey>中间的XXXXX-XXXXX-XXXXX-XXXXX-XXXXX，要怎么写呢？求助

<Key>
  <ProductKey>XXXXX-XXXXX-XXXXX-XXXXX-XXXXX</ProductKey>
  <ProductKeyID>0000000000000</ProductKeyID>
  <ProductKeyState>2</ProductKeyState>
  <ProductKeyPartNumber>000-00000</ProductKeyPartNumber>
</Key>
