Class XSDValidator

java.lang.Object

oracle.xml.schemavalidator.XSDValidator

public class XSDValidator
extends java.lang.Object

This class encapsulates the oracle.xml.parser.schema.XSDValidator class and adds functionalities for validating a DOM tree. The schema document is a constant and the validation is done for XMLDocuments that can be passed as InputStreams,URLs etc. The validation is done only after the DOM tree is built in all the cases. Nodes with errors are returned in a vector of stack trees where the top element of the stack represents the root node and child nodes are obtained by popping the elemnts of the stack.
