Non validating dom parser
Those events are passed to event handlers, which provide access to the contents of the document.
Event Handlers There are three classes of event handlers: DTDHandlers, for accessing the contents of XML Document-Type Definitions; Error Handlers, for low-level access to parsing errors; and, by far the most often used, Document Handlers, for accessing the contents of the document.
You can also modify the document by adding or removing Nodes.
The Dom tree is composed of nodes and they are of 12 types: SAX PARSING TECHNIQUE SAX (Simple API for XML) is an event-driven model for processing XML. Rather than building a complete representation of the document, a SAX parser fires off a series of events as it reads the document from beginning to end.
Disadvantage: The data is broken into pieces and clients never have all the information as a whole unless they create their own data structure.
To know the actual test status, someone must examine the result of each passed negative test (and informative test) to make sure it failed for the right reason.
At the core of the DOM API are the Document and Node interfaces.
The steps involved are a) Get an instance of DOM parser b) Create a new Document c) Load the Data d) Create a DOM tree with this Data e) Print the DOM tree which will be the XML file In detail a) Get an instance of DOM psrser to the same directory where you have downloaded these programs.
6.1.1 Using DOM parses a XML file and prints it on the console . This is a two stage process, first it parses the XML file and creates a tree structure in the memory.
The next stage is to traverse the tree and print the contents.
The first step we should do is to learn how to parse and print a simple XML document using both DOM and SAX.
This will help you to get the basic concepts in parsing and how does DOM API differ from SAX.
Mapping is the way of transforming one XML structure to another XML Structure bsed on the Business rules. But in case of graphical mapping XI/PI converts the mapping program into executable Java code internally based on graphical design and executes it on J2ee engine making it comparatively less efficiency.
