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 books in the object model to STDERR. + +To run the example on the sample XML instance document simply execute: + +$ ./driver library.xml diff --git a/xsd/examples/cxx/tree/caching/driver.cxx b/xsd/examples/cxx/tree/caching/driver.cxx new file mode 100644 index 0000000..a3877d8 --- /dev/null +++ b/xsd/examples/cxx/tree/caching/driver.cxx @@ -0,0 +1,209 @@ +// file      : examples/cxx/tree/caching/driver.cxx +// author    : Boris Kolpackov <boris@codesynthesis.com> +// copyright : not copyrighted - public domain + +#include <memory>   // std::auto_ptr +#include <fstream> +#include <iostream> + +#include <xercesc/dom/DOM.hpp> +#include <xercesc/util/XMLUniDefs.hpp> // chLatin_* +#include <xercesc/util/PlatformUtils.hpp> +#include <xercesc/validators/common/Grammar.hpp> // xercesc::Grammar +#include <xercesc/framework/Wrapper4InputSource.hpp> + +#include <xsd/cxx/xml/dom/auto-ptr.hxx> +#include <xsd/cxx/xml/dom/bits/error-handler-proxy.hxx> +#include <xsd/cxx/xml/sax/std-input-source.hxx> + +#include <xsd/cxx/tree/error-handler.hxx> + +#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<DOMLSParser> 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.
