These are generated by XSD from library.xsd. + +driver.cxx + Driver for the example. It first sets up the Xerces-C++ DOM parser + and caches the library.xsd schema for validation. It then performs + ten iterations that parse the input file to a DOM document using + the DOM parser and call one of the parsing functions that constructs + the object model from this DOM document. On each iteration the driver + prints a number of book in the object model to STDERR. + +To run the example on the sample XML instance document simply execute: + +$ ./driver library.xml diff --git a/examples/cxx/tree/caching/driver.cxx b/examples/cxx/tree/caching/driver.cxx new file mode 100644 index 0000000..5c3405a --- /dev/null +++ b/examples/cxx/tree/caching/driver.cxx @@ -0,0 +1,179 @@ +// file : examples/cxx/tree/caching/driver.cxx +// author : Boris Kolpackov +// copyright : not copyrighted - public domain + +#include // std::auto_ptr +#include +#include + +#include +#include // chLatin_* +#include +#include // xercesc::Grammar +#include + +#include +#include +#include + +#include +#include + +#include "library.hxx" + +using namespace std; + +int +main (int argc, char* argv[]) +{ + if (argc != 2) + { + cerr << "usage: " << argv[0] << " library.xml" << endl; + return 1; + } + + int r (0); + + // We need to initialize the Xerces-C++ runtime because we + // are doing the XML-to-DOM parsing ourselves. + // + xercesc::XMLPlatformUtils::Initialize (); + + try + { + using namespace xercesc; + namespace xml = xsd::cxx::xml; + namespace tree = xsd::cxx::tree; + + const XMLCh ls_id [] = {chLatin_L, chLatin_S, chNull}; + + // Get an implementation of the Load-Store (LS) interface. + // + DOMImplementation* impl ( + DOMImplementationRegistry::getDOMImplementation (ls_id)); + +#if _XERCES_VERSION >= 30000 + + // Xerces-C++ 3.0.0 and later. + // + xml::dom::auto_ptr parser ( + impl->createLSParser (DOMImplementationLS::MODE_SYNCHRONOUS, 0)); + + DOMConfiguration* conf (parser->getDomConfig ()); + + // Discard comment nodes in the document. + // + conf->setParameter (XMLUni::fgDOMComments, false); + + // Enable datatype normalization. + // + conf->setParameter (XMLUni::fgDOMDatatypeNormalization, true); + + // Do not create EntityReference nodes in the DOM tree.
