Description: As the name implies, the Java API for XML Processing (JAXP) is an API designed to help you write programs for processing XML documents. JAXP is very important for many reasons, not the least of which is the fact that it is a critical part of the Java Web Services Developer Pack (JWSDP). As you are probably already aware, web services is expected by many to be a very important aspect of the Internet of the future. This is the third lesson in a series designed to initially help you understand how to use JAXP, and to eventually help you understand how to use the JWSDP.
