Parsing non-consistent XML-object using Poweshell

I'm trying to parse an XML which doesn't consist of uniform attributes. Example

<root>
<object>
  <name>Object1</name>
  <valueString>string</valueString>
</object>
<object>
  <name>Object2</name>
  <valueBoolean>true</valueBoolean>
</object>
</root>

The number of sub attributes is always the same but sometimes its a boolean and sometimes its a string and the tage name changes accordingly. The issue is not the type itself but with Powershell I have to know the tag name beforehand to obtain the value attached to it.

At the moment I'm doing something like this:

foreach($item in $items){
  if(!$item.object.valueString){
     $temp = $item.object.valueBoolean
  }
  else{
     $temp = $item.object.valueString
  }
  $properties = @{
      Name = $item.object.Name
      value = $temp
  }
}

This works but I would like a more elegant solution + at the moment its quite rigid and you have to cater for each and every possibility.

Is there a better way ?

Cheers
