XML has spread like wildfire within the IT community. Microsoft has fully embraced it within the .NET initiative, and the Web service movement is fuelled by XML. Most developers have some firsthand experience with XML, but how can you quantify this XML knowledge? Certification is the answer with IBM's Certified Developer -- XML and Related Technologies exam. Some of the key features of XML are as follows:
- XML is an open standard: The language is not controlled or owned by one entity.
- XML can be extended: XML tags can be created by anyone and utilised by others.
- XML is a markup language, with similarities to HTML.
- Well-formed vs. validated XML
- Parsing -- the difference and aspects of both DOM and SAX
- Transformation -- XSLT basics
- Validation -- the differences and aspects of both schemas and DTDs
- XML security basics (signature and encryption)
- Xpath basics
- Utilise namespaces
- Using cascading style sheets (CSS) to transform or produce XML
- Determine the implications of a given architecture on XML design considerations
- Select appropriate XML technologies for an architecture (XML Schema 1.0, XSLT 1.0, DOM2, SAX2, XPath 1.0, Namespaces, DTDs)
- Design functional components and interconnections for an XML application architecture
- Assess performance trade-offs related to parsing, validation, and transformation
