What is XML Binding

PREVIOUS NEXT

XML data binding is the process of representing the information in an XML document as an object in computer memory (deserialization). This allows applications to access the XML data direct from the object, rather than using the Document Object Model (DOM) to retrieve it from the XML file. This means that XML binding enables you to integrate XML data into a business rule application.

In JRules, XML data binding is carried out in two stages:

  1. At compile time, the XML Schema Definition (XSD) is processed using a schema driver. This generates an Executable Object Model (XOM). The XOM describes how the XML document and your objects are structured. The XSD is the data model and the XML document is an intantiation of this model. See Stage 1: XML Schema Processing for details.
  2. At runtime, the XML document is processed using an XML data driver, to create an XML object. See Stage 2: XML Document Processing for details.

ILOG JRules exercises the Java class IlrXmlDefaultDataDriver, which implements the IlrXmlDataDriver interface, for both these drivers.
