Deleting specific subchild of XML file

[Aashu10]

In my xml file i have a node whose subchilder have 2 attributes, i have to delete 1 whole subchild while considering only 1 attribute. I have given an example below

XML file:

<UMG>
  <UMG_VAR Name="ABC" Value="1"></UMG_VAR>
  <UMG_VAR Name="ABC1" Value="2"></UMG_VAR>
  <UMG_VAR Name="ABC2" Value="3"></UMG_VAR>
  <UMG_VAR Name="ABC3" Value="4"></UMG_VAR>
  <UMG_VAR Name="ABC4" Value="5"></UMG_VAR>
</UMG>

I have to delete the whole subchild with only "Name" attribute, because Value can be changed.

My code until now:

void::MainWindow::XML()
{
    QString path = ui->lineEdit_7->text();

    qDebug()<<path;
    if(!file.exists() )
        {
        qDebug() << "Check your file";
    }
    QDomDocument dom;
    dom.setContent(&file);
    QDomNodeList nodes = dom.elementsByTagName("UMG");

    QDomNodeList loc_childNodes = nodes.at(0).childNodes();

    for(int i=0; i<loc_childNodes.count(); i++)
    {
        QDomNode node = loc_childNodes.at(i);
        qDebug() << node.attributes().namedItem("Name").nodeValue(); // I get all Name attributes.

last qDebug gives me all "Name" attributes. I am stuck at deleting the subchild with using this information.

edit:
Expected xml file:

<UMG>
  <UMG_VAR Name="ABC" Value="1"></UMG_VAR>
  <UMG_VAR Name="ABC1" Value="2"></UMG_VAR>
  <UMG_VAR Name="ABC2" Value="3"></UMG_VAR>
  <UMG_VAR Name="ABC3" Value="4"></UMG_VAR>
</UMG>

I'm not sure what you're asking. Do you want to remove an attribute or a whole node? Could you post an xml result you would like to get?

@Chris-Kawa Edited, added expected result, i want to delete the last subchild(just an example)

[Chris Kawa]

Removing last UMG_VAR node would look something like this:

QDomNodeList umgVars = dom.elementsByTagName("UMG_VAR");
if(!umgVars.isEmpty())
{
    QDomNode lastElem = umgVars.at(umgVars.size() - 1);
    lastElem.parentNode().removeChild(lastElem);
}
