在EmacsXML模式下，如何设置XML模式文件的格式？

我想自动格式化XML模式定义文件。所有正常的漂亮打印内容：结束元素后的换行符，缩进。我已经看过了，而且，这给了我一些基本知识。不过，除此之外，我希望在尖括号内的属性之间使用换行符

像这样。之前：

<s:schema elementFormDefault="qualified" targetNamespace="urn:Cheeso.2009.05.Finance/TransferObject/TransactionDetail/" xmlns:tns="urn:Cheeso.2009.05.Finance/TransferObject/TransactionDetail/"  xmlns:detail="urn:Cheeso.2009.05.Finance/TransferObject/TransactionDetail/"  xmlns:to="urn:Cheeso.2009.05.Finance/TransferObject/"  xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:address="urn:Cheeso.2009.05.Finance/TransferObject/Address/" xmlns:caller="urn:Cheeso.2009.05.Finance/TransferObject/Caller/" xmlns:gwy="urn:Cheeso.2009.05.Finance/TransferObject/Gateway/" xmlns:tender="urn:Cheeso.2009.05.Finance/TransferObject/Tender/"  >
 ...
</s:schema>

...

之后：

<s:schema
    elementFormDefault = "qualified"
    targetNamespace    = "urn:Cheeso.2009.05.Finance/TransferObject/TransactionDetail/"
    xmlns:tns          = "urn:Cheeso.2009.05.Finance/TransferObject/TransactionDetail/"
    xmlns:detail       = "urn:Cheeso.2009.05.Finance/TransferObject/TransactionDetail/"
    xmlns:to           = "urn:Cheeso.2009.05.Finance/TransferObject/"
    xmlns:s            = "http://www.w3.org/2001/XMLSchema"
    xmlns:address      = "urn:Cheeso.2009.05.Finance/TransferObject/Address/"
    xmlns:caller       = "urn:Cheeso.2009.05.Finance/TransferObject/Caller/"
    xmlns:gwy          = "urn:Cheeso.2009.05.Finance/TransferObject/Gateway/"
    xmlns:tender       = "urn:Cheeso.2009.05.Finance/TransferObject/Tender/"  >
 ...
</s:schema>

...

有人能推荐一些可以排列=？

的elisp吗？尝试以下方法：

(defun prettyprint-xml ()
  (interactive)
  (goto-char (point-min))
  (while (search-forward "=" (point-max) t)
    (search-forward "\"")
    (search-forward "\"")
    (forward-char)
    (newline-and-indent))
  (align-regexp (point-min) (point-max) "\#"))

它可能不完全符合您的要求（我只是编写了代码），但它看起来应该适用于您展示的案例
