自动格式化OS X/macOS XML属性列表'；s缩进和自动关闭标记样式

我想自动格式化一个或多个OS X/macOS XML属性列表文件，以使用类似于在其上运行“

xmllint--format

”的格式，除了：

• 我希望关键点的值在其父关键点下同样缩进一级（两个空格）
• 我不希望具有“
  ”值的键跨多行拆分

我还希望所有的自动关闭标记在其关闭斜杠之前都有空格。我将使用什么XSLT（编辑：或其他）转换来实现这一点

根据要求，这里是一个最简单的工作示例（稍微改编自：）

这不是我想要的，但为了完整起见，我添加了它。）

• 之后：

FWIW，以下是您自己缩进输出的方法：

XSLT1.0

<xsl:stylesheet version="1.0"

演示：

请添加输入和预期输出的示例-请参阅：。我现在添加了一个示例。恐怕这些都不可行或实用。1.键不是其值的父项，而是兄弟项。即使您设法使一个值相对于其键缩进，也将消除该值与其子项之间的缩进差异。除非你自己做缩进，这是可能的，但工作量很大。2.XSLT不会跨多行分割数据（除非您明确指示并为其构建机制）；如果不希望换行，请调整查看应用程序的首选项。我不知道如何在元素名中添加空格（这是您最后一个请求的结果）。元素名称不能包含空格字符。如果您试图添加它，您将得到一个错误，或者处理器将忽略它。您可以通过调整XSLT处理器的设置来实现这一点，但不能通过样式表。我不知道其他的工具。重新分割数据，我的意思是，默认情况下，文本节点的传递是不变的。关于元素之间的空白，有各种各样的选择，我在这里不一一列举。非常感谢！这比手工插入缩进要容易得多。嗯，我认为我的本地版本的“

xmllint

”和“

xsltproc

”有缺陷。我现在只使用该web链接，因为它可以工作，以后再处理本地包管理……它对我使用

xsltproc

很好，但有一个例外：XML声明和根元素之间有一个空行。macOS 10.13.6中包含的版本：“使用libxml 20904、libxslt 10129和libexslt 817 xsltproc是针对libxml 20904编译的，libxslt 10129和libexslt 817 libxslt 10129是针对libxml 20904编译的，libexslt 817 libxslt 10129是针对libxml 20904编译的”如果您传递一个名为

indent

的参数，它将被忽略，因为没有具有该名称的全局参数。另外，

indent

不用于确定要缩进的行。它用于确定缩进量-IOW，即当前元素的开始标记之前要输出的字符串。由于处理沿着树递归，并且每一代都会向它传递给其子代的缩进中添加一个缩进单元，因此会得到一个属性缩进树（w
