I'm using ETC version 10.5.2 and I'm trying to parse a existing attribute name, agentDomain, that does not contains an underscore character,"_", I tried setting the Condition/Matching Operator to "Contains RegEx" and the Condition Value to"(?!.*_)(.*)/(.*)" and it works on the Regular Expression Test Page for Java (RegexPlanet: online regular expression testing for Java), but when I create the attribute rule, the modified Component count is 0. Any Suggestion?
I was thinking about setting the Condition/Matching Operator to "Doesn't Contains RegEx", but couldn't figure out how to format the condition value or couldn't found any examples.
