SOX is an alternative (156) for XML. It is useful for reading and creating XML content in a (157) editor. It is then easily transformed into proper XML. SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML (158) have not reached a point where their tree views, tables and forms can completely substitute for the underlying (159) language. This is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as Java. SOX uses (160) to represent the structure of an XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surprisingly clear.

SOX是另外一种XML语法，可以用它在文本编辑中阅读和生成XML内容。它也很容易转换成适当的XML文档。SOX的产生是由于开发人员在处理原始的XML文档时花费了大量的时间。对很多人来说，通常的XML编辑器还没有达到可以用树图、表格和窗体来完全代替基本标记语言的地步。这是很自然的，因为有些人认为开发人员还在使用文本界面编辑其他语言，例如，Java。 SOX使用了锯齿状缩进的方式来表示XML文档的结构，这就不需要使用括号和引用设备编号了，其结果是显而易见的。
