Answer 1

If the reason to process 100 orders at a time is for performance purposes, e.g. taking too much time and resource to open a big file, You can utilize XmlReader to process order element one at a time without degrading the performance.

XmlReader reader = XmlReader.Create(@"c:\foo\Doket.xml")
while( reader.Read())
{
  if(reader.LocalName == "order")
  {
     // read each child element and its value from the reader.
     // or you can deserialize the order element by using a XmlSerializer and Order class
  }     
}
