Field Detail

_currentback to summary
protected ElementImpl _current

The current node in the document into which elements, text and other nodes will be inserted. This starts as the document itself and reflects each element that is currently being parsed.

_documentback to summary
protected HTMLDocumentImpl _document

The document that is being built.

_doneback to summary
private boolean _done

Indicates whether finished building a document. If so, can start building another document. Must be initially true to get the first document processed.

_ignoreWhitespaceback to summary
private boolean _ignoreWhitespace

Applies only to whitespace appearing between element tags in element content, as per the SAX definition, and true by default.

_preRootNodesback to summary
protected Vector<E> _preRootNodes

The document is only created the same time as the document element, however, certain nodes may precede the document element (comment and PI), and they are accumulated in this vector.

Method Detail

charactersback to summary
public void characters(String text) throws SAXException
charactersback to summary
public void characters(char[] text, int start, int length) throws SAXException

Implements org.xml.sax.DocumentHandler.characters.

Doc from org.xml.sax.DocumentHandler.characters.

Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).

Parameters
text:char[]

The characters from the XML document.

start:int

The start position in the array.

length:int

The number of characters to read from the array.

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
endDocumentback to summary
public void endDocument() throws SAXException

Implements org.xml.sax.DocumentHandler.endDocument.

Doc from org.xml.sax.DocumentHandler.endDocument.

Receive notification of the end of a document.

The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
endElementback to summary
public void endElement(String tagName) throws SAXException

Implements org.xml.sax.DocumentHandler.endElement.

Doc from org.xml.sax.DocumentHandler.endElement.

Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).

If the element name has a namespace prefix, the prefix will still be attached to the name.

Parameters
tagName:String

The element type name

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
getHTMLDocumentback to summary
public HTMLDocument getHTMLDocument()
ignorableWhitespaceback to summary
public void ignorableWhitespace(char[] text, int start, int length) throws SAXException

Implements org.xml.sax.DocumentHandler.ignorableWhitespace.

Doc from org.xml.sax.DocumentHandler.ignorableWhitespace.

Receive notification of ignorable whitespace in element content.

Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Parameters
text:char[]

The characters from the XML document.

start:int

The start position in the array.

length:int

The number of characters to read from the array.

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
processingInstructionback to summary
public void processingInstruction(String target, String instruction) throws SAXException

Implements org.xml.sax.DocumentHandler.processingInstruction.

Doc from org.xml.sax.DocumentHandler.processingInstruction.

Receive notification of a processing instruction.

The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.

A SAX parser should never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.

Parameters
target:String

The processing instruction target.

instruction:String

The processing instruction data, or null if none was supplied.

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
setDocumentLocatorback to summary
public void setDocumentLocator(Locator locator)

Implements org.xml.sax.DocumentHandler.setDocumentLocator.

Doc from org.xml.sax.DocumentHandler.setDocumentLocator.

Receive an object for locating the origin of SAX document events.

SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the DocumentHandler interface.

The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.

Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.

Parameters
locator:Locator

An object that can return the location of any SAX document event.

startDocumentback to summary
public void startDocument() throws SAXException

Implements org.xml.sax.DocumentHandler.startDocument.

Doc from org.xml.sax.DocumentHandler.startDocument.

Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
startElementback to summary
public synchronized void startElement(String tagName, AttributeList attrList) throws SAXException

Implements org.xml.sax.DocumentHandler.startElement.

Doc from org.xml.sax.DocumentHandler.startElement.

Deprecated

as a consequence of AttributeList being deprecated. See corresponding docs for further information.

Receive notification of the beginning of an element.

The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement() event for every startElement() event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement() event.

If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.

Parameters
tagName:String

The element type name.

attrList:AttributeList

The attributes attached to the element, if any.

Exceptions
SAXException:
Any SAX exception, possibly wrapping another exception.
