SOX is an alternative （1） for XML. It is useful for reading and creating XML content in a （2） 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 （3） have not reached a point where their tree views, tables and forms can completely substitute for the underlying （4） 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 （5） 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.
