https://community.cloudera.com/t5/Support-Questions/NiFi-Extract-atrribute-value-from-XML-using-EvaluateXPath/m-p/180271#M142517 <P>I can't reproduce this, I used GenerateFlowFile with your input XML (adding two Transactions) -&gt; SplitXML (level 1) and got the same "sub-xml" you did, then I used the same settings for EvaluateXPath and my content attribute has the correct value of 1. The only way I got it to show "Empty string set" is when I used /Transaction/@type as the XPath (note the wrong case for Type/type), is it possible there's a typo or case-sensitivity issue between your input XML and the XPath?</P> Thu, 26 Apr 2018 21:46:53 GMT mburgess 2018-04-26T21:46:53Z
