Non validating dom parser
NWDS provides suitable Java environment and higher level tools to parse XML documents through the Simple API for XML (SAX) and the Document Object Model (DOM) interfaces.
The SAX and DOM parsers are standards that are implemented in several different languages. SAX Parsing Parsing is a technique of reading and identifying XML tags from an XML document.
Diagnostics for failed tests are presented in italics, with a cherry colored background, to highlight the result.
Diagnostics for succesful tests should as a rule only exist for negative tests.
A non validating parser doesn't validate the XML file against a DTD or XML Schema.
You can query nodes for their parent, their siblings, or their children.In the Java programming language, you can instantiate the parsers by using the Java API for XML Parsing (JAXP). DOM and SAX can either be a validating or a non validating parser.A validating parser checks the XML file against the rules imposed by DTD or XML Schema.When a Sax parser parses a XML document and every time it encounters a tag it calls the corresponding tag handler methods when it encounter a Start Tag it calls this method public void start Element(String name, Attribute List attrs) when it encounter a End Tag it calls this method public void end Element(String name) This program also parses a XML file and prints it on the console . In this example, the Print Using Sax Class extends the Handler Base class and implemets the call back methods to handle the printing The steps involved are Get a instance of SAX parser, The previous program illustrated how to Parse an existing XML file using both SAX and DOM Parsers.But generating a XML file from scratch is a different story , for instance you might like to generate a xml file for the data extracted form the database.
