how to determine an empty node

Hello friends.

I have the following XML file:

Code:

---

<settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="/home/user/.config/application/config.xsd">
  <app>
    <applicationdisplayname>My Application Display Name</applicationdisplayname>
    <applicationhashkey>a9cd0d49e19637c0fea893d12ac87f64</applicationhashkey>
    <applicationname>MyApplicationName</applicationname>
    <applicationversion>1.0</applicationversion>
    <organizationname>MyOrganizationName</organizationname>
    <organizationdomain>https://www.myorganizationdomain.com</organizationdomain>
    <showsplash>1</showsplash>
    <iconimage>icono.png</iconimage>
    <mayorversion>5</mayorversion>
    <minorversion>0</minorversion>
    <pathversion>0</pathversion>
  </app>
</settings>

I'm trying to go through this file, which I do correctly, the detail is when I try to make the following comparison:

Code:

---

if ( element.nodeValue ().isEmpty () ) {
 
 
}

---

where element is a QDomElement, when making this comparison, either in the node configuration or node application, they return the following information:

Code:

---

My Application Display Namea9cd0d49e19637c0fea893d12ac87f64MyApplicationName1.0MyOrganizationNamehttps: //www.myorganizationdomain.com1icono.png500

I've been searching the documentation and forums for a long time but I do not get to achieve this

My point is, how do I determine if the node or application settings do not have values ​​directly as well as the applicationdisplayname node.

Or if there is any post in this forum that you have not seen, I would greatly appreciate the help.

Thanks in advance.
