Class XmlReader

A generic XML reader template -- by itself, does nothing. The actual readers are XmlCmlReader, XmlMolproReader (which is an extension of XmlCmlReader), XmlChem3dReader, and XmlOdysseyReader. XmlReader takes all XML streams, whether from a file reader or from DOM. This class functions as a resolver, since it: (1) identifying the specific strain of XML to be handled, and (2) passing the responsibility on to the correct format-specific XML readers. There are parallel entry points and handler methods for reader and DOM. Each format-specific XML reader then assigns its own handler to manage the parsing of elements. In addition, this class handles generic XML tag parsing. XmlHandler extends DefaultHandler is the generic interface to both reader and DOM element parsing. XmlCmlReader extends XmlReader XmlMolproReader extends XmlCmlReader. If you feel like expanding on that, feel free. XmlChem3dReader extends XmlReader. That one is simple; no need to expand on it at this time. XmlOdysseyReader extends XmlReader. That one is simple; no need to expand on it at this time. Note that the tag processing routines are shared between SAX and DOM processors. This means that attributes must be transformed from either Attributes (SAX) or JSObjects (DOM) to Hashtable name:value pairs. This is taken care of in JmolXmlHandler for all readers. TODO 27/8/06: Several aspects of CifReader are NOT YET implemented here. These include loading a specific model when there are several, applying the symmetry, and loading fractional coordinates.
