/* This is simple demonstration of how to use expat. This program
|
|
reads an XML document from standard input and writes a line with
|
|
the name of each element to standard output indenting child
|
|
elements by one tab stop more than their parent element.
|
|
It must be used with Expat compiled for UTF-8 output.
