/**
 * section: Parsing
 * synopsis: Parse an XML document chunk by chunk to a tree and free it
 * purpose: Demonstrate the use of xmlCreatePushParserCtxt() and
 *          xmlParseChunk() to read an XML file progressively
 *          into a tree and xmlFreeDoc() to free the resulting tree
 * usage: parse4 test3.xml
 * test: parse4 test3.xml
