DESCRIPTION
The QXmlSimpleReader class provides an implementation of a simple XML
reader (parser).
This XML reader is sufficient for simple parsing tasks. The reader:
provides a well-formed parser;
does not parse any external entities;
can do namespace processing.
Documents are parsed with a call to parse().
See also XML.
MEMBER FUNCTION DOCUMENTATIONQXmlSimpleReader::QXmlSimpleReader ()
Constructs a simple XML reader with the following feature settings:
<center>.nf
</center>
More information about features can be found in the Qt SAX2 overview.
See also setFeature().
QXmlSimpleReader::~QXmlSimpleReader () [virtual]
Destroys the simple XML reader.
bool QXmlSimpleReader::parse ( const QXmlInputSource * input, bool incremental
) [virtual]
Reads an XML document from input and parses it. Returns FALSE if the
parsing detects an error; otherwise returns TRUE.
If incremental is TRUE, the parser does not return FALSE when it
reaches the end of the input without reaching the end of the XML file.
Instead it stores the state of the parser so that parsing can be
continued at a later stage when more data is available. You can use the
function parseContinue() to continue with parsing. This class stores a
pointer to the input source input and the parseContinue() function
tries to read from that input souce. This means that you should not
delete the input source input until you've finished your calls to
parseContinue(). If you call this function with incremental TRUE whilst
an incremental parse is in progress a new parsing session will be
started and the previous session lost.
If incremental is FALSE, this function behaves like the normal parse
function, i.e. it returns FALSE when the end of input is reached
without reaching the end of the XML file and the parsing cannot be
continued.
See also parseContinue() and QSocket.
Examples:
bool QXmlSimpleReader::parseContinue () [virtual]
Continues incremental parsing; this function reads the input from the
QXmlInputSource that was specified with the last parse() command. To
use this function, you must have called parse() with the incremental
argument set to TRUE.
Returns FALSE if a parsing error occurs; otherwise returns TRUE.
If the input source returns an empty string for the function
QXmlInputSource::data(), then this means that the end of the XML file
has been reached; this is quite important, especially if you want to
use the reader to parse more than one XML file.
The case of the end of the XML file being reached without having
finished parsing is not considered to be an error: you can continue
parsing at a later stage by calling this function again when there is
more data available to parse.
This function assumes that the end of the XML document is reached if
the QXmlInputSource::next() function returns
QXmlInputSource::EndOfDocument. If the parser has not finished parsing
when it encounters this symbol, it is an error and FALSE is returned.
See also parse() and QXmlInputSource::next().
void QXmlSimpleReader::setFeature ( const QString & name, bool value )
[virtual]
Sets the state of the feature name to value:
If the feature is not recognized, it is ignored.
The following features are supported: <center>.nf
</center>
