This example is similar to the 'caching' -example except that it loads the binary representation of the schemas -embedded into the application instead of pre-parsing external schema files. - -The example consists of the following files: - -xsdbin.cxx - Tool for converting one or more XML Schema files to the compressed binary - representation. The output is written as a pair of C++ source files - containing the array with the binary data. Use the --help option to see - the tool's usage information. - -library.xsd - XML Schema which describes a library of books. - -library.xml - Sample XML instance document. - -library.hxx -library.cxx - C++ types that represent the given vocabulary and a set of parsing - functions that convert XML instance documents to a tree-like in-memory - object model. These are generated by the XSD compiler from library.xsd. - -library-schema.hxx -library-schema.cxx - Binary representation of the library.xsd schema. These files are generated - by the xsdbin tool. - -grammar-input-stream.hxx -grammar-input-stream.cxx - Input stream implementation with the special-purpose schema grammar - decompression algorithm. It is used to load the binary schema representation - produced by the xsdbin tool. - -driver.cxx - Driver for the example. It first sets up the Xerces-C++ DOM parser and - loads the embedded binary schema grammar 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/examples/cxx/tree/embedded/driver.cxx b/examples/cxx/tree/embedded/driver.cxx deleted file mode 100644 index 5ceafa4..0000000 --- a/examples/cxx/tree/embedded/driver.cxx +++ /dev/null @@ -1,183 +0,0 @@ -// file : examples/cxx/tree/embedded/driver.cxx -// 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 <xercesc/framework/XMLGrammarPoolImpl.hpp> - -#include <xsd/cxx/xml/string.hxx> -#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" -#include "library-schema.hxx" -#include "grammar-input-stream.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; - - // Create and load the grammar pool. - // - MemoryManager* mm (XMLPlatformUtils::fgMemoryManager); - - auto_ptr<XMLGrammarPool> gp (new XMLGrammarPoolImpl (mm)); - - try - { - grammar_input_stream is (library_schema, sizeof (library_schema)); - gp->deserializeGrammars(&is); - } - catch(const XSerializationException& e) - { - cerr << "unable to load schema: " << - xml::transcode<char> (e.getMessage ()) << endl; - return 1; - } - - // Lock the grammar pool.
