https://community.cloudera.com/t5/Support-Questions/How-does-EvaluateXPath-processor-in-NIFI-use-XPaths-in-its/m-p/178273#M140520 <P>I have found that valid XPath expressions apparently produce empty strings in EvaluateXPath processor. In the attached screenshots only //@categoryId and //@UniqueType seem to work. I am using nifi 1.7.1 and jdk1.8.0_181.jdk. Any help would be appreciated!</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="88462-flowfileattributes.png" style="width: 1522px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/19504iABE71E112651EF14/image-size/medium?v=v2&amp;px=400" role="button" title="88462-flowfileattributes.png" alt="88462-flowfileattributes.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="88461-evaluatexpath-properties.png" style="width: 1610px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/19505i503D9FB63FDA3854/image-size/medium?v=v2&amp;px=400" role="button" title="88461-evaluatexpath-properties.png" alt="88461-evaluatexpath-properties.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="88460-examplexmlfile.png" style="width: 1999px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/19506iC28FB0D335D9AC85/image-size/medium?v=v2&amp;px=400" role="button" title="88460-examplexmlfile.png" alt="88460-examplexmlfile.png" /></span></P><P><a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/47339">@dmueller1607</a></P><P><a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/38301">@mburgess</a></P><P><a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/35449">@alopresto</a></P> Sun, 18 Aug 2019 09:35:14 GMT cdilcher 2019-08-18T09:35:14Z
