About: VTD-XML is a “non-extractive” XML processing software API implementing Virtual Token Descriptor. Currently, it only supports built-in entity references (” &s; ' > <). Designed to be random-access capable, it attempts to be both high-performance and memory-efficient. In addition, because VTD is inherent persistent, it can be saved on disk along side the XML document to achieve "parse-once, use many times." The "non-extractive" nature of VTD means that incremental, dynamic updates don't require re-serialization of irrelevant parts of the original document.
