> camel-xslt - XPath evaluation fails in Java DSL routes
> ------------------------------------------------------
>
> Key: CAMEL-20438
> URL: https://issues.apache.org/jira/browse/CAMEL-20438
> Project: Camel
> Issue Type: Bug
> Components: camel-xslt
> Affects Versions: 4.4.0
> Reporter: Alexandru Neaţă
> Priority: Minor
> Fix For: 4.4.1, 4.5.0
>
>
> The following route fails to evaluate the {*}xpath{*}:
> {code:java}
> from("direct:hello")
> .routeId("xpath-route")
> .setBody(xpath("//hello/id", Integer.class))
> .to("direct:goodbye");
> {code}
> There seems to be an issue with the instance of [QName|https://docs.oracle.com/en/java/javase/17/docs/api/java.xml/javax/xml/namespace/QName.html] used. I think it should be [XPathConstants.NODESET|https://docs.oracle.com/en/java/javase/17/docs/api/java.xml/javax/xml/xpath/XPathConstants.html#NODESET] but instead it is a custom instance with nulled *namespace* field.
> Full project example: [https://github.com/alex-nt/issues-java/tree/main/camel/camel-xpath]
> Running *mvn clean install* in the module should reproduce the issue.
