/**
|
|
* section: xmlReader
|
|
* synopsis: Parse and validate an XML file with an xmlReader
|
|
* purpose: Demonstrate the use of xmlReaderForFile() to parse an XML file
|
|
* validating the content in the process and activating options
|
|
* like entities substitution, and DTD attributes defaulting.
|
|
* (Note that the XMLReader functions require libxml2 version later
|
|
* than 2.6.)
|
|
* usage: reader2 <valid_xml_filename>
|
|
* test: reader2 test2.xml > reader1.tmp && diff reader1.tmp $(srcdir)/reader1.res
