Extract XML Fragment Using Extended VTD-XML

// This example demonstrate how to use extended vtd-xml to extract content out
// of a huge xml document. Notie that the parsing is set to memory mapped mode
// so that the processed file can exceed the size of physical memory.
// unlike standard VTD-XML, getElementFragment() of VTDNavHuge returns a array
// of longs, otherwise, null will be returned.
