Chapter 15. XML

15.1. The XML Format

Warning

The XML rule language has not been updated to support functionality introduced in Drools 5.x and is consider a deprecated feature.
As an option, JBoss Rules supports a "native" rule language as an alternative to DRL. This allows you to capture and manage your rules as XML data. Just like the non-XML DRL format, the XML format is parsed into the internal "AST" representation as fast as possible (using a SAX parser). There is no external transformation step required.
