Simple Rule Engine / News: Recent posts

complete rewrite. chainable rule engine, now with rules that flow from one to the other.

Simple Rule Engine Version 2.0 is almost ready for release.

We recomment that if you plan on using SRE as a parser that iterates through a nodeset and potentially creates a new set to wait for version 2.0. Version 2.0 will contain a decision tree engine along with its current decision table engine, decision trees allow for easy construction of iterators.

added an action for callbacks

fixed a bug related to dependent defects, when a rules dependent facts(or rules) change, it should be nulled out and reevaluated. Otherwise if the old value was true and the new value was true it didnt fire any event stating it changed. this is critical when a facts value can changed based on a xpath expression with an xpath indexer.

Rules are now executed upon modification to an XmlDocument object. Many major changes. View the documentation for details.

Major changes for evaluating expressions in this release, SRE now converts infix expressions to postfix for evaluation. The expression evaluator is now capable of mathmatical expressions, set evaluation, and custom functions with minor code changes.
