Method Detail

startDocument

public void startDocument(XMLLocator locator,
                          java.lang.String encoding,
                          Augmentations augs)
                   throws XNIException
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).
augs - Additional information that may include infoset augmentations
Throws:
XNIException - Thrown by handler to signal an error.

xmlDecl

public void xmlDecl(java.lang.String version,
                    java.lang.String encoding,
                    java.lang.String standalone,
                    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.

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(java.lang.String rootElement,
                        java.lang.String publicId,
                        java.lang.String systemId,
                        Augmentations augs)
                 throws XNIException
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.

comment

public void comment(XMLString text,
                    Augmentations augs)
             throws XNIException
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.

processingInstruction

public void processingInstruction(java.lang.String target,

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

                        throws XNIException
The start of a namespace prefix mapping. This method will only be called when namespace processing is enabled.

Parameters:
prefix - The namespace prefix.
uri - The URI bound to the prefix.
augs - Additional information that may include infoset augmentations
Throws:

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.
