Method Detail

characters

boolean characters(java.lang.String ch)
The reader calls this function when it has parsed a chunk of character data (either normal character data or character data inside a CDATA section; if you need to distinguish between those two types you must use QXmlLexicalHandler::startCDATA() and QXmlLexicalHandler::endCDATA()). The character data is reported in ch.

Some readers report whitespace in element content using the ignorableWhitespace() function rather than using this one.

A reader may report the character data of an element in more than one chunk; e.g. a reader might want to report "a<b" in three characters() events ("a ", "<" and " b").

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.


endDocument

boolean endDocument()
The reader calls this function after it has finished parsing. It is called just once, and is the last handler function called. It is called after the reader has read all input or has abandoned parsing because of a fatal error.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

See also:
startDocument().


endElement

boolean endElement(java.lang.String namespaceURI,
                   java.lang.String localName,
                   java.lang.String qName)
The reader calls this function when it has parsed an end element tag with the qualified name qName, the local name localName and the namespace URI namespaceURI.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

startElement(), and Namespace Support via Features.


endPrefixMapping

boolean endPrefixMapping(java.lang.String prefix)
The reader calls this function to signal the end of a prefix mapping for the prefix prefix.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

See also:
startPrefixMapping(), and Namespace Support via Features.


errorString

java.lang.String errorString()
The reader calls this function to get an error string, e.g. if any of the handler functions returns false.


ignorableWhitespace

boolean ignorableWhitespace(java.lang.String ch)
Some readers may use this function to report each chunk of whitespace in element content. The whitespace is reported in ch.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.


processingInstruction

boolean processingInstruction(java.lang.String target,
                              java.lang.String data)
The reader calls this function when it has parsed a processing instruction.

target is the target name of the processing instruction and data is the data in the processing instruction.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.


setDocumentLocator

void setDocumentLocator(QXmlLocator locator)
The reader calls this function before it starts parsing the document. The argument locator is a pointer to a QXmlLocator which allows the application to get the parsing position within the document.

Do not destroy the locator; it is destroyed when the reader is destroyed. (Do not use the locator after the reader is destroyed).


skippedEntity

boolean skippedEntity(java.lang.String name)
Some readers may skip entities if they have not seen the declarations (e. . because they are in an external DTD). If they do so they report that they skipped the entity called name by calling this function.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.


startDocument

boolean startDocument()
The reader calls this function when it starts parsing the document. The reader calls this function just once, after the call to setDocumentLocator(), and before any other functions in this class or in the QXmlDTDHandler class are called.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

See also:
endDocument().


startElement

boolean startElement(java.lang.String namespaceURI,
                     java.lang.String localName,
                     java.lang.String qName,
                     QXmlAttributes atts)
The reader calls this function when it has parsed a start element tag.

There is a corresponding endElement() call when the corresponding end element tag is read. The startElement() and endElement() calls are always nested correctly. Empty element tags (e.g. <x/>) cause a startElement() call to be immediately followed by an endElement() call.

The attribute list provided only contains attributes with explicit values. The attribute list contains attributes used for namespace declaration (i.e. attributes starting with xmlns) only if the namespace-prefix property of the reader is true.

The argument namespaceURI is the namespace URI, or an empty string if the element has no namespace URI or if no namespace processing is done. localName is the local name (without prefix), or an empty string if no namespace processing is done, qName is the qualified name (with prefix) and atts are the attributes attached to the element. If there are no attributes, atts is an empty attributes object.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.

endElement(), and Namespace Support via Features.


startPrefixMapping

boolean startPrefixMapping(java.lang.String prefix,
                           java.lang.String uri)
The reader calls this function to signal the begin of a prefix-URI namespace mapping scope. This information is not necessary for normal namespace processing since the reader automatically replaces prefixes for element and attribute names.

Note that startPrefixMapping() and endPrefixMapping() calls are not guaranteed to be properly nested relative to each other: all startPrefixMapping() events occur before the corresponding startElement() event, and all endPrefixMapping() events occur after the corresponding endElement() event, but their order is not otherwise guaranteed.

The argument prefix is the namespace prefix being declared and the argument uri is the namespace URI the prefix is mapped to.

If this function returns false the reader stops parsing and reports an error. The reader uses the function errorString() to get the error message.
