Only the effective (first) declaration for an attribute will be reported. The type will be one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION", or a parenthesized token group with the separator "|" and all whitespace removed.
Parameters: eName The name of the associated element. aName The name of the attribute. type A string representing the attribute type. valueDefault A string representing the attribute default ("#IMPLIED", "#REQUIRED", or "#FIXED") or null if none of these applies. value A string representing the attribute's default value, or null if there is none.
Throws: SAXException The application may raise an exception.
By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).
Parameters: ch The characters. start The start position in the character array. length The number of characters to use from the character array.
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException

This callback will be used for comments inside or outside the document element, including comments in the external DTD subset (if read).
Parameters: ch An array holding the characters in the comment. start The starting position in the array. length The number of characters to use from the array.
Throws: SAXException The application may raise an exception.
The content model will consist of the string "EMPTY", the string "ANY", or a parenthesised group, optionally followed by an occurrence indicator. The model will be normalized so that all whitespace is removed,and will include the enclosing parentheses.
Parameters: name The element type name. model The content model as a normalized string.
Throws: SAXException The application may raise an exception.
Throws: SAXException The application may raise an exception.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.ContentHandler#endDocument
Throws: SAXException The application may raise an exception.
See Also: TransformerIdentityImpl
By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).
Parameters: uri The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed. localName The local name (without prefix), or the empty string if Namespace processing is not being performed. qName The qualified name (with prefix), or the empty string if qualified names are not available.

Only the effective (first) declaration for each entity will be reported.
Parameters: name The name of the entity. If it is a parameter entity, the name will begin with '%'. publicId The declared public identifier of the entity, or null if none was declared. systemId The declared system identifier of the entity.
Throws: SAXException The application may raise an exception.

Returns: The current error handler, which should never be null.
The properties returned should contain properties set by the user, and properties set by the stylesheet, and these properties are "defaulted" by default properties specified by section 16 of the XSL Transformations (XSLT) W3C Recommendation. The properties that were specifically set by the user or the stylesheet should be in the base Properties list, while the XSLT default properties that were not specifically set should be the default Properties list. Thus, getOutputProperties().getProperty(String key) will obtain any property in that was set by {@link #setOutputProperty}, {@link #setOutputProperties}, in the stylesheet, or the default properties, while getOutputProperties().get(String key) will only retrieve properties that were explicitly set by {@link #setOutputProperty}, {@link #setOutputProperties}, or in the stylesheet.
Note that mutation of the Properties object returned will not effect the properties that the transformation contains.
If any of the argument keys are not recognized and are not namespace qualified, the property will be ignored. In other words the behaviour is not orthogonal with setOutputProperties.
Returns: A copy of the set of output properties in effect for the next transformation.
See Also: javax.xml.transform.OutputKeys java.util.Properties
Parameters: name A non-null String that specifies an output property name, which may be namespace qualified.
Returns: The string value of the output property, or null if no property was found.
Throws: IllegalArgumentException If the property is not supported.
See Also: javax.xml.transform.OutputKeys
This method does not return a default parameter value, which cannot be determined until the node context is evaluated during the transformation process.
Parameters: name Name of the parameter.
Returns: A parameter that has been set with setParameter.
Returns: The systemID that was set with {@link #setSystemId}.
Returns: non-null reference to the transformer.
Returns: An object that implements the URIResolver interface, or null.
By default, do nothing. Application writers may override this method to take specific actions for each chunk of ignorable whitespace (such as adding data to a node or buffer, or printing it to a file).
Parameters: ch The whitespace characters. start The start position in the character array. length The number of characters to use from the character array.
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.ContentHandler#ignorableWhitespace
Only the effective (first) declaration for each entity will be reported.
Parameters: name The name of the entity. If it is a parameter entity, the name will begin with '%'. value The replacement text of the entity.
Throws: SAXException The application may raise an exception.
See Also: TransformerIdentityImpl org.xml.sax.DTDHandler#unparsedEntityDecl
By default, do nothing. Application writers may override this method in a subclass if they wish to keep track of the notations declared in a document.
Parameters: name The notation name. publicId The notation public identifier, or null if not available. systemId The notation system identifier.
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.DTDHandler#notationDecl
By default, do nothing. Application writers may override this method in a subclass to take specific actions for each processing instruction, such as setting status variables or invoking other methods.
Parameters: target The processing instruction target. data The processing instruction data, or null if none is supplied.
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.ContentHandler#processingInstruction
By default, do nothing. Application writers may override this method in a subclass if they wish to store the locator for use with other document events.
Parameters: locator A locator for all SAX document events.
See Also: org.xml.sax.ContentHandler#setDocumentLocator org.xml.sax.Locator
Parameters: listener The new error listener.
Throws: IllegalArgumentException if listener is null.
If argument to this function is null, any properties previously set are removed, and the value will revert to the value defined in the templates object.
Pass a qualified property key name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used.
Parameters: oformat A set of output properties that will be used to override any of the same properties in affect for the transformation.
Throws: IllegalArgumentException if any of the argument keys are not recognized and are not namespace qualified.
See Also: javax.xml.transform.OutputKeys java.util.Properties
Pass a qualified property name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used.
The Properties object that was passed to {@link #setOutputProperties} won't be effected by calling this method.
Parameters: name A non-null String that specifies an output property name, which may be namespace qualified. value The non-null string value of the output property.
Throws: IllegalArgumentException If the property is not supported, and is not qualified with a namespace.
See Also: javax.xml.transform.OutputKeys
Pass a qualified name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used.
Parameters: name The name of the parameter, which may begin with a namespace URI in curly braces ({}). value The value object. This can be any valid Java object. It is up to the processor to provide the proper object coersion or to simply pass the object on for use in an extension.
Parameters: result A Result instance, should not be null.
Throws: IllegalArgumentException if result is invalid for some reason.
Parameters: systemID Base URI for the source tree.
If the resolver argument is null, the URIResolver value will be cleared, and the default behavior will be used.
Parameters: resolver An object that implements the URIResolver interface, or null.
By default, do nothing. Application writers may override this method in a subclass to take specific actions for each processing instruction, such as setting status variables or invoking other methods.
Parameters: name The name of the skipped entity.
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.ContentHandler#processingInstruction
The contents of the CDATA section will be reported through the regular {@link org.xml.sax.ContentHandler#characters characters} event.
Throws: SAXException The application may raise an exception.
See Also: TransformerIdentityImpl
By default, do nothing. Application writers may override this method in a subclass to take specific actions at the beginning of a document (such as allocating the root node of a tree or creating an output file).
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.ContentHandler#startDocument
Any declarations are assumed to be in the internal subset unless otherwise indicated by a {@link #startEntity startEntity} event.
Note that the start/endDTD events will appear within the start/endDocument events from ContentHandler and before the first startElement event.
Parameters: name The document type name. publicId The declared public identifier for the external DTD subset, or null if none was declared. systemId The declared system identifier for the external DTD subset, or null if none was declared.
Throws: SAXException The application may raise an exception.

Parameters: uri The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed. localName The local name (without prefix), or the empty string if Namespace processing is not being performed. qName The qualified name (with prefix), or the empty string if qualified names are not available. attributes The specified or defaulted attributes.
Throws: org.xml.sax.SAXException Any SAX exception, possibly wrapping another exception. SAXException
See Also: org.xml.sax.ContentHandler#startElement
NOTE: entity references in attribute values -- and the start and end of the document entity -- are never reported.
The start and end of the external DTD subset are reported using the pseudo-name "[dtd]". All other events must be properly nested within start/end entity events.
