XML Programming - Basic

This exam tests your knowledge of popular Java APIs for reading and manipulating XML:

SAX (Simple API for XML)
StAX (Streaming API for XML)
JDOM
XStream (an API for serializing objects to XML)

The knowledge required to pass the XML Core - Basic exam is a prerequisite for this one. Therefore questions on general XML knowledge are out of scope for this exam.

	Released	Beta	Frozen
SAX Simple API for XML
Principle 1 question Understand that SAX follows an event-driven push model. Understand that SAX doesn't require to load the whole file XML document in memory. Understand that SAX is composed of 2 parts (+ your code = 3 parts): org.xml.sax interfaces and an implementation (as Xerces).	2	32	9	Add a question Beta questions
XMLReader 1 question Know how to turn the validation on/off for DTDs and Schemas with Xerces. Get an XMLReader from a XMLReaderFactory. Link a ContentHandler to the reader. Parse a document and catch appropriate exceptions.	3	0	6	Add a question Beta questions
ContentHandler 3 questions Understand the purpose and basic usage of each method of the ContentHandler interface. The features, properties, and filters are not part of this exam.	4	0	14	Add a question Beta questions
StAX Streaming API for XML
Principle 1 question Know the mechanism difference between SAX and StAX (push event vs pull)	7	9	6	Add a question Beta questions
API 1 question Know how to get an XMLStreamReader from an XMLInputFactory. Get the next event and identify its type (from start/end document, start/end element, character). Get the content: name of an element, text content of an element, attribute values of an element.	4	0	5	Add a question Beta questions
JDOM
Principle 1 question Understand that Dom and JDom are tree-based pull models. Understand the core differences between JDom and DOM: DOM exists in multiple programming languages, JDom is a Java API. DOM is a specification and needs an implementation, JDom is a direct implementation with no separated specs. JDom wants to be simpler to use than DOM. Both load the XML tree in memory.	4	10	10	Add a question Beta questions
Builders 1 question Know that JDom uses a parser (SAX or DOM) to read XML files and build its tree. Know the basic usage of the SAXBuilder.	1	1	13	Add a question Beta questions
Document 3 questions Know how to use the main classes for representing an XML document and their relationships: Document, Element, Attribute, Text. Be able to navigate through the tree of elements (recursively if necessary).	5	1	24	Add a question Beta questions
Output 1 question Know the basic usage of the XMLOutputter and Format classes.	5	0	7	Add a question Beta questions
XStream 1 question (Based on versions up to 1.1.x) Use XStream to convert a POJO graph into an XML file and back, including managing the graph boundaries. Basic usage of the XStream.alias method. Note: converters are out of scope.	4	7	8	Add a question Beta questions
