Examples of org.bifrost.xmlio.XmlReader

org.bifrost.xmlio.XmlReader

Read data from an XML file into a graph of objects. One or more objects get created as a result of parsing an XML file.

Created: Feb 22, 2003
Copyright: Copyright (c) 2003
Assumptions: none
Requires: ReaderContentHandler, XmlException
Required by: nothing
Revision History:
2003-04-21 Changed to use JAXP instead of Xerces.
2004-04-14 Support for a configuration object

Example:

 XmlReader reader = new XmlReader("filename.xml", "base.pkg.of.classes"); SalesLot rootObject = (SalesLot)reader.getRootObject(); Could read a structure like this (where SalesLot is the root Java object  and the root XML element): <SalesLot>   <Car>     <make>Saab</make>     <model>93</model>     <year>2001</year>   </Car>   <Car>     <make>Saab</make>     <model>95</model>     <year>2002</year>   </Car> </SalesLot> The SalesLot object would implement a method called addCar(Car newCar) which would add each of the Car elements to a Collection. Car would implement setMake(String theMake), setModel(String theModel) and setYear(String theYear).
