Class Overview

The document handler interface defines callback methods to report information items in XML documents. Parser components interested in document information implement this interface and are registered as the document handler on the document source.

Character content.

Parameters
text The content.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void comment (XMLString text, Augmentations augs)

A comment.

Parameters
text The text in the comment.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by application to signal an error.

public abstract void doctypeDecl (String rootElement, String publicId, String systemId, Augmentations augs)

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

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 otherwise.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void emptyElement (QName element, XMLAttributes attributes, Augmentations augs)

An empty element.

Parameters
element The name of the element.
attributes The element attributes.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void endCDATA (Augmentations augs)

The end of a CDATA section.

Parameters
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void endDocument (Augmentations augs)

The end of the document.

Parameters
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void endElement (QName element, Augmentations augs)

The end of an element.

Parameters
element The name of the element.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void endGeneralEntity (String name, Augmentations augs)

This method notifies the end of a general entity.

Note: This method is not called for entity references appearing as part of attribute values.

Parameters
name The name of the entity.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract XMLDocumentSource getDocumentSource ()

Returns the document source.

public abstract void ignorableWhitespace (XMLString text, Augmentations augs)

Ignorable whitespace. For this method to be called, the document source must have some way of determining that the text containing only whitespace characters should be considered ignorable. For example, the validator can determine if a length of whitespace characters in the document are ignorable based on the element content model.

Parameters
text The ignorable whitespace.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void processingInstruction (String target, XMLString data, Augmentations augs)

A processing instruction. Processing instructions consist of a target name and, optionally, text data. The data is only meaningful to the application.

Typically, a processing instruction's data will contain a series of pseudo-attributes. These pseudo-attributes follow the form of element attributes but are not parsed or presented to the application as anything other than text. The application is responsible for parsing the data.

Parameters
target The target.
data The data or null if none specified.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void setDocumentSource (XMLDocumentSource source)

Sets the document source.

public abstract void startCDATA (Augmentations augs)

The start of a CDATA section.

Parameters
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void startDocument (XMLLocator locator, String encoding, NamespaceContext namespaceContext, Augmentations augs)

The start of the document.

Parameters
locator The document locator, or null if the document location cannot be reported during the parsing of this document. However, it is strongly recommended that a locator be supplied that can at least report the system identifier of the document.
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.

public abstract void startElement (QName element, XMLAttributes attributes, Augmentations augs)

The start of an element.

Parameters
element The name of the element.
attributes The element attributes.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void startGeneralEntity (String name, XMLResourceIdentifier identifier, String encoding, Augmentations augs)

This method notifies the start of a general entity.

Note: This method is not called for entity references appearing as part of attribute values.

Parameters
name The name of the general entity.
identifier The resource identifier.
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).
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void textDecl (String version, String encoding, Augmentations augs)

Notifies of the presence of a TextDecl line in an entity. If present, this method will be called immediately following the startEntity call.

Note: This method will never be called for the document entity; it is only called for external general entities referenced in document content.

Note: This method is not called for entity references appearing as part of attribute values.

Parameters
version The XML version, or null if not specified.
encoding The IANA encoding name of the entity.
augs Additional information that may include infoset augmentations
Throws
XNIException Thrown by handler to signal an error.

public abstract void xmlDecl (String version, String encoding, String standalone, Augmentations augs)

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

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.
