Wrap up
Here in Part 2 of this tutorial series on preparing for the IBM XML certification exam, we have covered the following technologies:
- XPath
- XSLT
- XLink
- XPointer
- CSS
- XSL-FO
- DOM
- SAX
XPath and XSLT go hand-in-hand. Most of the exam questions related to these technologies will ask you to evaluate the output of specific XSLT stylesheets, or test you on the functions available in XPath and XSLT. Few if any questions will focus on XLink, XPointer, CSS, or XSL-FO, and those that do will be very basic. Questions relating to DOM and SAX should be relatively easy compared with questions on the other technologies. A basic understanding of these APIs should be sufficient to help you answer the exam questions.
As stated in Part 1, it is important to understand how all these technologies work apart from memorizing their syntax. In order to answer scenario-based questions, you should know the advantages and disadvantages of these various technologies. In the exam, you have to choose one of several possible solutions for a given question, so it's important to know how the technologies compare to one another. For example, SAX relative to DOM and CSS relative to XSLT.
Now that we've covered the various technologies on the exam, the third part of this series will show you how these technologies map to the exam objectives.
