Method Details

startDTD

void startDTD(XMLLocator locator,
 Augmentations augmentations)
       throws XNIException

The start of the DTD.

Parameters:

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

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

startParameterEntity

void startParameterEntity(String name,
 XMLResourceIdentifier identifier,
 String encoding,
 Augmentations augmentations)
                   throws XNIException

This method notifies of the start of a parameter entity. The parameter entity name start with a '%' character.

Parameters:

name - The name of the parameter 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 parameter entities).

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

textDecl

void textDecl(String version,
 String encoding,
 Augmentations augmentations)
       throws XNIException

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 is only called for external parameter entities referenced in the DTD.

Parameters:

version - The XML version, or null if not specified.

encoding - The IANA encoding name of the entity.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

endParameterEntity

void endParameterEntity(String name,
 Augmentations augmentations)
                 throws XNIException

This method notifies the end of a parameter entity. Parameter entity names begin with a '%' character.

Parameters:

name - The name of the parameter entity.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

startExternalSubset

void startExternalSubset(XMLResourceIdentifier identifier,
 Augmentations augmentations)
                  throws XNIException

The start of the DTD external subset.

Parameters:

identifier - The resource identifier.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

endExternalSubset

void endExternalSubset(Augmentations augmentations)
                throws XNIException

The end of the DTD external subset.

Parameters:

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

comment

void comment(XMLString text,
 Augmentations augmentations)
      throws XNIException

A comment.

Parameters:

text - The text in the comment.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by application to signal an error.

processingInstruction

void processingInstruction(String target,
 XMLString data,
 Augmentations augmentations)
                    throws XNIException

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.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

 Augmentations augmentations)
          throws XNIException

An element declaration.

Parameters:

name - The name of the element.

contentModel - The element content model.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

startAttlist

void startAttlist(String elementName,
 Augmentations augmentations)
           throws XNIException

The start of an attribute list.

Parameters:

elementName - The name of the element that this attribute list is associated with.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

enumeration - If the type has the value "ENUMERATION" or "NOTATION", this array holds the allowed attribute values; otherwise, this array is null.

defaultType - The attribute default type. This value will be one of the following: "#FIXED", "#IMPLIED", "#REQUIRED", or null.

defaultValue - The attribute default value, or null if no default value is specified.

nonNormalizedDefaultValue - The attribute default value with no normalization performed, or null if no default value is specified.
