Therefore, the JAXP 1.1 Expert Group (EG) introduced a set of APIs called Transformation API for XML (Tr AX) in JAXP 1.1, and since then, JAXP is called Java API for XML Processing.Thereafter, JAXP has evolved to an extent, where now it supports a lot more things (like validation against schema while parsing, validation against preparsed schema, evaluating XPath expressions, etc.,) than only parsing an XML document.The chapter introduces the Xerces download component, its integrated parser, documentation, and samples.You may use these samples as frameworks for further development.Along the way, the chapter introduces every important class and interface, so that by the end of the chapter, you will be adept in the construction of XML applications.We assume that you have at least an intermediate comfort level with Java, that you understand the concepts of paths and classpaths, that you have utilized Java packages, classes, and interfaces, and that you have experience writing, compiling, and running applications.
In the following we are going to see a demo application which output all SAX events.
Since these are checked exceptions, you’ll need to either catch these exceptions or declare that your method throws them. However, most parsers also support some non-standard, custom properties.
The names of these will begin with URLs somewhere in the parser vendor’s domain.
SAX is fast and efficient and it is useful for state-independent filtering.
SAX parser calls a method when an element tag is encountered and calls a different method when text is found.
If you meet these requirements, and are comfortable with previous chapters, then hop on board.
