Örnekler

Aşağıdaki örnek, UnknownAttributes.xml adlı bir dosyadan adlı Group sınıfı seri durumdan kaldırır. sınıfında karşılık gelen üyesi olmayan dosyada bir öğe bulunduğunda, UnknownAttribute olay gerçekleşir. Örneği denemek için aşağıdaki XML kodunu UnknownAttributes.xml adlı bir dosyaya yapıştırın.

<?xml version="1.0" encoding="utf-8"?>  
<Group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" GroupType = 'Technical' GroupNumber = '42' GroupBase = 'Red'>
