* 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
