For many of us, the popular XML(72)have not reached a point where their tree views, tables and forms can completely substitute for the underlying.(73)language. This is not surprising when one considers that developers still use a(74)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.
