Hi, I've been trying to add an item using the XML XPath preprocessing for a VMware ESXi Patch Tracker RSS feed located in https://esxi-patches.v-front.de/atom/ESXi-6.5.0.xml

The XML document contains the following excerpt:
<?xml version="1.0" encoding="utf-8" ?>
<feed xmlns="http://www.w3.org/2005/Atom">

<title type="text">ESXi 6.5.0 Patch Tracker</title>
...
The bold parameter above is giving empty result for any query. This will not happen if there is additional ":atom" suffix added to the parameter like this:
<feed xmlns:atom="http://www.w3.org/2005/Atom">
 
Steps to reproduce: # Add new item of type HTTP agent to a host

1. Specify Preprocessing step "XML XPath" with parameters, for example /feed/title for the above example.
2. Click on "Test" to test the XPath preprocessing and fill in the XML document without ":atom" suffix.

Result:
The result of the test returns "empty string"

Expected:
Should returns "<title type="text">ESXi 6.5.0 Patch Tracker</title>"
