W3C_XML_SCHEMA_NS_URI); try catch (SAXException e) catch (IOException e) but you could just as easily validate against a local file.
In the context of Extensible Markup Language (XML), validation normally involves writing a detailed specification for the document's contents in any of several schema languages such as the World Wide Web Consortium (W3C) XML Schema Language (XSD), RELAX NG, Document Type Definitions (DTDs), and Schematron.Sometimes validation is performed while parsing, sometimes immediately after. Sun's JDK 6 uses SAX parser with a Stream Source. @ziggy - this is an implementation detail of the JAXP implementation.However, it's usually done before any further processing of the input takes place.
(This description is painted with broad strokes -- there are exceptions.)Until recently, the exact Application Programming Interface (API) by which programs requested validation varied with the schema language and parser.
It usually emphasizes the importance of grammatical divisions such as subject and predicate.
Within computational linguistics the term is used to refer to the formal analysis by a computer of a sentence or other string of words into its constituents, resulting in a parse tree showing their syntactic relation to each other, which may also contain semantic and other information.
The term has slightly different meanings in different branches of linguistics and computer science.
Traditional sentence parsing is often performed as a method of understanding the exact meaning of a sentence or word, sometimes with the aid of devices such as sentence diagrams.
For example, the tree structure of the "bookstore.xml" is as follows: An XML document comprises of the following basic units: to XML parser or an application program that uses the XML document.
