Class AbstractXMLDocumentParser

java.lang.Object

net.sourceforge.htmlunit.xerces.parsers.XMLParser

net.sourceforge.htmlunit.xerces.parsers.AbstractXMLDocumentParser

All Implemented Interfaces:

XMLDocumentHandler

Direct Known Subclasses:

AbstractDOMParser, AbstractSAXParser

public abstract class AbstractXMLDocumentParser
extends XMLParser
implements XMLDocumentHandler

This is the base class for all XML document parsers. XMLDocumentParser provides a common implementation shared by the various document parsers in the Xerces package. While this class is provided for convenience, it does not prevent other kinds of parsers to be constructed using the XNI interfaces.

Method Detail

startDocument

public void startDocument(XMLLocator locator,
                          String encoding,
                          NamespaceContext namespaceContext,

                   throws XNIException

The start of the document.

Specified by:

startDocument in interface XMLDocumentHandler

Parameters:

locator - The system identifier of the entity if the entity is external, null otherwise.

encoding - The auto-detected IANA encoding name of the entity stream. This value will be null in those situations where the entity encoding is not auto-detected (e.g. internal entities or a document entity that is parsed from a java.io.Reader).

namespaceContext - The namespace context in effect at the start of this document. This object represents the current context. Implementors of this class are responsible for copying the namespace bindings from the the current context (and its parent contexts) if that information is important.

augs - Additional information that may include infoset augmentations

Throws:

XNIException - Thrown by handler to signal an error.

xmlDecl

public void xmlDecl(String version,
                    String encoding,

                    Augmentations augs)
             throws XNIException

Notifies of the presence of an XMLDecl line in the document. If present, this method will be called immediately following the startDocument call.

Specified by:

xmlDecl in interface XMLDocumentHandler

Parameters:

version - The XML version.

encoding - The IANA encoding name of the document, or null if not specified.

standalone - The standalone value, or null if not specified.

augs - Additional information that may include infoset augmentations

Throws:

XNIException - Thrown by handler to signal an error.

doctypeDecl

public void doctypeDecl(String rootElement,
                        String publicId,

                        Augmentations augs)
                 throws XNIException

Notifies of the presence of the DOCTYPE line in the document.

Specified by:

doctypeDecl in interface XMLDocumentHandler

Parameters:

rootElement - The name of the root element.

publicId - The public identifier if an external DTD or null if the external DTD is specified using SYSTEM.

systemId - The system identifier if an external DTD, null

augs - Additional information that may include infoset augmentations otherwise.

Throws:

XNIException - Thrown by handler to signal an error.

startElement

public void startElement(QName element,
                         XMLAttributes attributes,

                  throws XNIException

Parameters:

element - The name of the element.

attributes - The element attributes.

augs - Additional information that may include infoset augmentations

Throws:
