33
Demo Xml parsing(1)

• 1. // prepare xml parsing settings
• XmlReaderSettings xmlSettings new
• XmlReaderSettings()
• xmlSettings.IgnoreComments true
• xmlSettings.IgnoreProcessingInstructions true
• xmlSettings.IgnoreWhitespace true
• xmlSettings.CloseInput true
• // create OPTIMIZED reader
• XmlReader reader XmlTextReader.Create(
  File.OpenRead(xmlPath), xmlSettings)

34
Demo Xml parsing(2)

1. while ( reader.Read() )
3. if (reader.Name "student"
   reader.IsStartElement() )
5. student new Student()
7. else
8. if (reader.Name "names"
   reader.IsStartElement() student ! null)
10. student.Names reader.ReadInnerXml()
11. More

35
Demo Xml parsing(3)

1. else
2. if (reader.Name "age" reader.IsStartElement(
   ) student ! null)
4. Student.Age Int32.Parse(reader.ReadInnerXml(),
   CultureInfo.InvariantCulture)
6. else
7. if (reader.Name "student"
   !reader.IsStartElement())
8. students.Add(student)

36
Demo Xml parsing(4)

1. ListBox lbStudents
3. ListltStudentgt students new ListltStudentgt()
4. // xml parsing
6. lbStudents.DataSource students

37
Demo Xml Deserialization

1. // create serializer instance
2. XmlSerializer serializer new XmlSerializer(
   typeof(ListltStudentgt) , new XmlRootAttribute("s
   tudents") )
3. // perform deserialization
4. lbStudents.DataSource serializer.Deserialize(
   File.OpenRead(xmlPath) )
