/* read in the rule set */ final RuleItem_RuleSet ruleSet = getRuleSet();
This line calls a utility method to read the rule set from an XML source file.
The rule set is explicitly validated to ensure that it contains no errors:
/* dump out any problems */ ruleSetXmlReader.validationProblemCollection().printProblems( System.err); /* fail if there are errors in the rule set */ assertTrue(!ruleSetXmlReader.validationProblemCollection() .containsErrors());
