Hello, I have a nifi processor which is receiving data through Syslog RFC5424. When i receive data, i use ParseSyslog5424 processor in order to get all attributes. Some attributes are variables. (in bold)   I can get : syslog.structuredData.15C81B70@14506.os or syslog.structuredData.hzhzd@14507.os ….   Then, i have configured RouteOnAttribute. For the moment i hard code this : Value : ${syslog.structuredData.15C81B70@14506.os:equals("linux69")} Value : ${syslog.structuredData.hzhzd@14507.os:equals("windows")}   I would like to know if there is a way to put an expression like : Value : ${syslog.structuredData.*.os:equals("linux69")}   I don't find an easy solution to do this.   Thanks. ...
