c# read from xml file

Hello,
 
I have and xml file, like this:
 

<MyXMLFile>
  <SerialNumber>111</SerialNumber>
  <Name>MyName</Name>
  <Size X="10" Y="12" />
  </MyXMLFile>

 
The user who creates the XML data file, can change the order of the elements.
For example, "size" element can be before "name" element.
 
I have to read the whole data of this file.
 
As far as I know, XMLReader can't go back from it's position.
So one solution I thought about, is to create an xml reader and destroy it, again and again.
For example:
 

            XmlReader xmlReader = XmlReader.Create(strXMLFileName);
 
            xmlReader.ReadToFollowing(XMLNODE_Size);
            int sizeX = Convert.ToInt32(xmlReader.GetAttribute("X"));    
            int sizeY= Convert.ToInt32(xmlReader.GetAttribute("Y"));
            xmlReader.Close();
 
            xmlReader = XmlReader.Create(strXMLFileName);
            xmlReader.ReadToFollowing(XMLNODE_NAME);
            xmlReader.ReadStartElement();
            string name = xmlReader.ReadString();
            xmlReader.ReadEndElement();
            xmlReader.Close();

 
Is there a better way to do it, instead of close and reopen the xmlReader?
(I want also to read the attibutes where there are.)
 
Thanks
