public voidemptyElement(com.sun.org.apache.xerces.internal.xni.QName element, com.sun.org.apache.xerces.internal.xni.XMLAttributes attributes, com.sun.org.apache.xerces.internal.xni.Augmentations augs)
An empty element.

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

public voidendCDATA(com.sun.org.apache.xerces.internal.xni.Augmentations augs)
The end of a CDATA section.

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

public voidendDocument(com.sun.org.apache.xerces.internal.xni.Augmentations augs)
The end of the document.

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

public voidendElement(com.sun.org.apache.xerces.internal.xni.QName element, com.sun.org.apache.xerces.internal.xni.Augmentations augs)
The end of an element.

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

public voidendGeneralEntity(java.lang.String name, com.sun.org.apache.xerces.internal.xni.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.

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

public com.sun.org.apache.xerces.internal.xni.parser.XMLDocumentSourcegetDocumentSource()
Returns the document source.

public voidignorableWhitespace(com.sun.org.apache.xerces.internal.xni.XMLString text, com.sun.org.apache.xerces.internal.xni.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.

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

public voidprocessingInstruction(java.lang.String target, com.sun.org.apache.xerces.internal.xni.XMLString data, com.sun.org.apache.xerces.internal.xni.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.

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

public voidsetDocumentSource(com.sun.org.apache.xerces.internal.xni.parser.XMLDocumentSource source)
Sets the document source.

public voidstartCDATA(com.sun.org.apache.xerces.internal.xni.Augmentations augs)
The start of a CDATA section.

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

public voidstartDocument(com.sun.org.apache.xerces.internal.xni.XMLLocator locator, java.lang.String encoding, com.sun.org.apache.xerces.internal.xni.NamespaceContext namespaceContext, com.sun.org.apache.xerces.internal.xni.Augmentations augs)
The start of the document.

param
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.
param
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).
param
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.
param
augs Additional information that may include infoset augmentations
exception
XNIException Thrown by handler to signal an error.

public voidstartElement(com.sun.org.apache.xerces.internal.xni.QName element, com.sun.org.apache.xerces.internal.xni.XMLAttributes attributes, com.sun.org.apache.xerces.internal.xni.Augmentations augs)
The start of an element.

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

This method notifies the start of a general entity.

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

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

public voidtextDecl(java.lang.String version, java.lang.String encoding, com.sun.org.apache.xerces.internal.xni.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.

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

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

param
version The XML version.
param
encoding The IANA encoding name of the document, or null if not specified.
param
standalone The standalone value, or null if not specified.
param
