I am trying to parse an XML file using C# in the .NET environment and it keeps skipping over elements

So this is how a portion of the XML I am trying to parse looks like:

<azsa:Views>
   <azsa:Spatial_Array>
      <azsa:Spatial>
         <azsa:ViewName>Spatial</azsa:ViewName>
            <azsa:BBox>
               <azsa:PointLo>
                 <azsa:x>0</azsa:x>
                 <azsa:y>0</azsa:y>
                 <azsa:z>0</azsa:z>
                </azsa:PointLo>
               <azsa:PointHi>
                 <azsa:x>2925</azsa:x>
                 <azsa:y>3375</azsa:y>
                 <azsa:z>2775</azsa:z>
               </azsa:PointHi>
             </azsa:BBox>
       </azsa:Spatial>
    </azsa:Spatial_Array>
</azsa:Views>

I have to read the x,y and z coordinates for both PointHi and PointLo

I was using the XMLReader() class to perform the task.

XmlTextReader reader = new XmlTextReader(openFileDialog1.FileName);

 while (reader.Read())
 {
   reader.ReadToFollowing("azsa:Views");
   reader.ReadToFollowing("azsa:Spatial_Array");
   reader.ReadToFollowing("azsa:Spatial");
   reader.ReadToFollowing("azsa:ViewName");
   reader.ReadToFollowing("azsa:BBox");
   reader.ReadToFollowing("azsa:PointLo");
   reader.ReadToFollowing("azsa:x");
   low[0] = (int)(Double.Parse(reader.ReadElementString()));
   reader.ReadToFollowing("azsa:y");
   low[1] = (int)(Double.Parse(reader.ReadElementString()));
   reader.ReadToFollowing("azsa:z");
   low[2] = (int)(Double.Parse(reader.ReadElementString()));
   reader.ReadToFollowing("azsa:PointHi");
   reader.ReadToFollowing("azsa:x");
   high[0] = (int)(Double.Parse(reader.ReadElementString()));
   reader.ReadToFollowing("azsa:y");
   high[1] = (int)(Double.Parse(reader.ReadElementString()));
   reader.ReadToFollowing("azsa:z");
   high[2] = (int)(Double.Parse(reader.ReadElementString()));
}

The reader works perfectly until it gets to the first x in the PointLo and then it just skips to the y in PointHi instead. I have tried using descendants, subtrees and readinnerxml but it still does the same thing.

NOTE: 1. There is more code in the while loop for reading the remaining part of the XML but was not necessary for this problem so I have not included it in the post. 2. Changing the way the XML is organized is not possible because that's how they are required to be stored for the task I am performing. 3. XMLReader is the preferable method as I am dealing with a large number of documents and there is no scope for having this use cache memory.
