https://community.cloudera.com/t5/Support-Questions/NIFI-How-can-I-validate-record/m-p/192068#M154145 <P>It's totally possible with Nifi!</P><P>There are a number of ways you could go about it, and it depends on if you think the dates will have the same format, or if they will vary. (ie: mm/dd/yyyy or dd-mm-yyyy)</P><P>I found another useful conversation <A href="https://community.hortonworks.com/questions/135093/nifi-expression-language-to-check-if-the-file-cont.html">here</A> that covers using the routeOnContent or routeOnText processors to evaluate a regex expression, checking if the value matches what you expect.</P><P>I would recommend looking at the documentation on those processors, as well as testing out your regex expression on a site like <A href="https://regexr.com/">Regexr</A>. Hope that gets you started!</P> Thu, 20 Sep 2018 21:37:22 GMT nlewis135031 2018-09-20T21:37:22Z
