Validating and non validating parsers with xml
I know parsing check file structure (grammar), so may be checked as OK in parsing function, but may be WRONG in validation process because there is no attr value like "pink"? Parsing checks that the input conforms to the rules in the XML specification, for example that every start tag has a matching end tag.
Validation checks that the input conforms to the rules of a specific XML vocabulary, for example that a table contains exactly one thead and one tbody.
An XML processor reads the XML file and turns it into in-memory structures that the rest of the program can access.
The most fundamental XML processor reads an XML document and converts it into an internal representation for other programs or subroutines to use.
Stylus Studio® X16 XML includes a built-in XML validator, and also fully supports industry XML components commonly used by developers, including: MSXML 4.0 SAX, MSXML 4.0 DOM, MSXML 6.0, Microsoft . XML), Xerces-J 2.5.1, XSV 2.6, and many other XML validators.
Sun's implementation supports any combination of configuration options.A few validating parsers are − xml4c (IBM, in C ), xml4j (IBM, in Java), MSXML (Microsoft, in Java), Tcl XML (TCL), xmlproc (Python), XML:: Parser (Perl), Java Project X (Sun, in Java).A few non-validating parsers are − Open XML (Java), Lark (Java), xp (Java), AElfred (Java), expat (C), XParse (Java Script), xmllib (Python).This is called a parser, and it is an important component of every XML processing program.Processor involves processing the instructions, that can be studied in the chapter Processing Instruction.
