How to add value to Config file using XmlFile

How do I set a value using XmlFile in this section?

<root>
<!--<appender-ref ref="RollingFileAppender" />-->
<level value="ALL"/>
</root>

i.e. I need to add this element and value

<appender-ref ref="RollingFileAppender" />

Is it possible to check if it exists and do not add?

XmlFile allows for conditionally adding elements and/or attributes by specifying the ElementPath attribute.

The following example installs the XML file File.xml and then adds an appender-ref element with the ref attribute set to RollingFileAppender unless there already exists an appender-ref element. Note that the XmlConfig element for adding the attribute value references the other element's ID through its ElementId attribute.

<Component>
  <File Source='$(sys.SOURCEFILEDIR)File.xml'/>
  <util:XmlConfig Id="CreateAppenderElement"
                  File="[#File.xml]"
                  Action="create"
                  ElementPath="/root"
                  VerifyPath="/root/appender-ref"
                  Name="appender-ref"
                  Node="element"
                  On="install">
    <util:XmlConfig Id="CreateAppenderElement_SetRef"
                    ElementId="CreateAppenderElement"
                    File="[#File.xml]"
                    Name="ref"
                    Value="RollingFileAppender"/>
  </util:XmlConfig>
</Component>
