/**
 * section: xmlReader
 * synopsis: Parse an XML file with an xmlReader
 * purpose: Demonstrate the use of xmlReaderForFile() to parse an XML file
 *          and dump the informations about the nodes found in the process.
 *          (Note that the XMLReader functions require libxml2 version later
 *          than 2.6.)
 * usage: reader1 <filename>
 * test: reader1 test2.xml > reader1.tmp && diff reader1.tmp $(srcdir)/reader1.res
 * author: Daniel Veillard
 * copy: see Copyright for the status of this software.
