1This example shows how to perform stream-oriented, partially in-memory 2XML processing using the C++/Tree mapping. With the partially in-memory 3parsing and serialization only a part of the object model is in memory at 4any given time. With this approach we can process parts of the document 5as they become available as well as handle documents that are too large 6to fit into memory. 7 8The example consists of the following files: 9 10position.xsd 11 XML Schema which describes a simple object position vocabulary. The 12 position is represented as a potentially large series of latitude and 13 longitude measurements. 14 15position.xml 16 Sample object position document. 17 18position.hxx 19position.cxx 20 C++ types that represent the position vocabulary as well as parsing 21 and serialization functions. These are generated by XSD from 22 position.xsd. 23 24parser.hxx 25parser.cxx 26 Stream-oriented DOM parser implementation that is built on top of the 27 Xerces-C++ SAX2 parser in the progressive parsing mode. This parser 28 allows us to parse an XML document as a series of DOM fragments. 29 30serializer.hxx 31serializer.cxx 32 Stream-oriented DOM serializer implementation that allows us to 33 serialize an XML Document as a series of object model fragments. 34 35grammar-input-stream.hxx 36grammar-input-stream.cxx 37 Input stream implementation with the special-purpose schema grammar 38 decompression algorithm. It is used internally by the streaming parser. 39 40driver.cxx 41 Driver for the example. It parses the input file into a series of DOM 42 fragments which are then parsed into the object model fragments. The 43 driver prints the information from the document as it becomes available. 44 It also serializes the object model fragments into a new XML document 45 (out.xml). 46 47To run the example simply execute: 48 49$ ./driver position.xml 50 51The serialization results are written to the out.xml file. 52
