  org.apache.xerces.impl.XMLScanner
      org.apache.xerces.impl.XMLDocumentFragmentScannerImpl

All Implemented Interfaces:

XMLEntityHandler, XMLComponent, XMLDocumentScanner, XMLDocumentSource

public class XMLNSDocumentScannerImpl
extends XMLDocumentScannerImpl

The scanner acts as the source for the document information which is communicated to the document handler. This class scans an XML document, checks if document has a DTD, and if DTD is not found the scanner will remove the DTD Validator from the pipeline and perform namespace binding. Note: This scanner should only be used when the namespace processing is on!

This component requires the following features and properties from the component manager that uses it:

• http://xml.org/sax/features/namespaces {true} -- if the value of this feature is set to false this scanner must not be used.
• http://xml.org/sax/features/validation
• http://apache.org/xml/features/nonvalidating/load-external-dtd
• http://apache.org/xml/features/scanner/notify-char-refs
• http://apache.org/xml/features/scanner/notify-builtin-refs
• http://apache.org/xml/properties/internal/symbol-table
• http://apache.org/xml/properties/internal/error-reporter
• http://apache.org/xml/properties/internal/entity-manager
