SOX is an alternative (71) for XML. It is useful for reading and creating XML content in a (72) 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 (73) have not reached a point where their tree views, tables and forms can completely substitute for the underlying (74) 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 (75) 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.
