Objectives

• Why an XML editor?
• To create, edit, correct, or simply view XML
• Schema inspection
• Schema validation
• Which one
• Altova XMLSpy (www.altova.com)
• Stylus Studio (www.stylusstudio.com)
• Oxygen (www.oxygenxml.com)
• Hands on experience with XMLSpy
• Working with XML to create basic EML
• Validation of EML
