org.apache.xerces.impl.XMLScanner

org.apache.xerces.impl.XMLDocumentFragmentScannerImpl

All Implemented Interfaces:

extends org.apache.xerces.impl.XMLScanner
implements org.apache.xerces.xni.parser.XMLDocumentScanner, org.apache.xerces.xni.parser.XMLComponent, org.apache.xerces.impl.XMLEntityHandler

This class is responsible for scanning the structure and content of document fragments. The scanner acts as the source for the document information which is communicated to the document handler.

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

• http://xml.org/sax/features/validation
• 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
