[jira] [Commented] (NIFI-5497) XPATH interpretation not correct

["Stefan Goldener (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-5497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16573246#comment-16573246 ] 

Stefan Goldener commented on NIFI-5497:
---------------------------------------

I still consider this as a BUG but for those who stumble upon this Jira there is a workaround:
{code:java}
//@*[name()="xlink:href"]{code}
or
{code:java}
//@*[local-name()="href"]{code}

> For example using the following XML:
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <item xmlns:xlink="http://www.w3.org/1999/xlink"
> a="17"
> date="2018-02-16T22:19:45+01:00"
>  xlink:href="http://url.com/webservice/rest/1.0/"/>{code}
>  
> With XPATH i can usually do:
> {code:java}
> //@xlink:href{code}
> to get the url.
>  
> This does not work with Nifi because it evaluates the XPath expression somehow incorrectly.
