\endif
\module XML
\ingroup xml-tools
All subclasses of TQXmlReader read the input XML document from this
class.
This class recognizes the encoding of the data by reading the
encoding declaration in the XML file if it finds one, and reading
the data using the corresponding encoding. If it does not find an
encoding declaration, then it assumes that the data is either in
UTF-8 or UTF-16, depending on whether it can find a byte-order
mark.
There are two ways to populate the input source with data: you can
construct it with a TQIODevice* so that the input source reads the
data from that device. Or you can set the data explicitly with one
of the setData() functions.
Usually you either construct a TQXmlInputSource that works on a
TQIODevice* or you construct an empty TQXmlInputSource and set the
data with setData(). There are only rare occasions where you would
want to mix both methods.
The TQXmlReader subclasses use the next() function to read the
input character by character. If you want to start from the
beginning again, use reset().
The functions data() and fetchData() are useful if you want to do
something with the data other than parsing, e.g. displaying the
raw XML file. The benefit of using the TQXmlInputClass in such
cases is that it tries to use the correct encoding.

\brief The TQXmlContentHandler class provides an interface to
report the logical content of XML data.
\if defined(commercial)
It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
\endif
\module XML
\ingroup xml-tools
If the application needs to be informed of basic parsing events,
it can implement this interface and activate it using
TQXmlReader::setContentHandler(). The reader can then report basic
document-related events like the start and end of elements and
character data through this interface.
The order of events in this interface is very important, and
mirrors the order of information in the document itself. For
example, all of an element's content (character data, processing
instructions, and sub-elements) appears, in order, between the
startElement() event and the corresponding endElement() event.
The class TQXmlDefaultHandler provides a default implementation for
this interface; subclassing from the TQXmlDefaultHandler class is
very convenient if you only want to be informed of some parsing
events.
The startDocument() function is called at the start of the
document, and endDocument() is called at the end. Before parsing
begins setDocumentLocator() is called. For each element
startElement() is called, with endElement() being called at the
end of each element. The characters() function is called with
chunks of character data; ignorableWhitespace() is called with
chunks of whitespace and processingInstruction() is called with
processing instructions. If an entity is skipped skippedEntity()
is called. At the beginning of prefix-URI scopes
startPrefixMapping() is called.

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

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. \c{<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 \a namespaceURI is the namespace URI, or
TQString::null if the element has no namespace URI or if no
namespace processing is done. \a localName is the local name
(without prefix), or TQString::null if no namespace processing is
done, \a qName is the qualified name (with prefix) and \a atts are
the attributes attached to the element. If there are no
attributes, \a atts is an empty attributes object.

\class TQXmlReader ntqxml.h
\reentrant
\brief The TQXmlReader class provides an interface for XML readers (i.e.
parsers).
\if defined(commercial)
It is part of the <a href="commercialeditions.html">TQt Enterprise Edition</a>.
\endif
\module XML
\ingroup xml-tools
This abstract class provides an interface for all of TQt's XML
readers. Currently there is only one implementation of a reader
included in TQt's XML module: TQXmlSimpleReader. In future releases
there might be more readers with different properties available
(e.g. a validating parser).
The design of the XML classes follows the \link
http://www.saxproject.org/ SAX2 Java interface\endlink, with
the names adapted to fit TQt naming conventions. It should be very
easy for anybody who has worked with SAX2 to get started with the
TQt XML classes.
All readers use the class TQXmlInputSource to read the input
document. Since you are normally interested in particular content
in the XML document, the reader reports the content through
special handler classes (TQXmlDTDHandler, TQXmlDeclHandler,
TQXmlContentHandler, TQXmlEntityResolver, TQXmlErrorHandler and
TQXmlLexicalHandler), which you must subclass, if you want to
process the contents.
Since the handler classes only describe interfaces you must
implement all the functions. We provide the TQXmlDefaultHandler
class to make this easier: it implements a default behaviour (do
nothing) for all functions, so you can subclass it and just
implement the functions you are interested in.
Features and properties of the reader can be set with setFeature()
and setProperty() respectively. You can set the reader to use your
own subclasses with setEntityResolver(), setDTDHandler(),
setContentHandler(), setErrorHandler(), setLexicalHandler() and
setDeclHandler(). The parse itself is started with a call to
parse().

Reads an XML document from \a input and parses it. Returns FALSE
if the parsing detects an error; otherwise returns TRUE.
If \a incremental is TRUE, the parser does not return FALSE when
it reaches the end of the \a 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 \a
input and the parseContinue() function tries to read from that
input souce. This means that you should not delete the input
source \a input until you've finished your calls to
parseContinue(). If you call this function with \a incremental
TRUE whilst an incremental parse is in progress a new parsing
session will be started and the previous session lost.
If \a 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.

Continues incremental parsing; this function reads the input from

Returns FALSE if a parsing error occurs; otherwise returns TRUE.
If the input source returns an empty string for the function
TQXmlInputSource::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 TQXmlInputSource::next() function returns
TQXmlInputSource::EndOfDocument. If the parser has not finished
parsing when it encounters this symbol, it is an error and FALSE
is returned.

/*
For the incremental parsing, it is very important that the parse...()
functions have a certain structure. Since it might be hard to understand how
they work, here is a description of the layout of these functions:
bool TQXmlSimpleReader::parse...()
{
(1) const signed char Init = 0;
...
(2) const signed char Inp... = 0;
...
(3) static signed char table[3][2] = {
...
};
signed char state;
signed char input;
(4) if (d->parseStack == 0 || d->parseStack->isEmpty()) {
(4a) ...
} else {
(4b) ...
}
for ( ; ; ) {
(5) switch ( state ) {
...
}
(6)
(6a) if ( atEnd() ) {
unexpectedEof( &TQXmlSimpleReader::parseNmtoken, state );
return FALSE;
}
(6b) if (determineNameChar(c) != NotName) {
...
}
(7) state = table[state][input];
(8) switch ( state ) {
...
}
}
}
Explanation:
ad 1: constants for the states (used in the transition table)
ad 2: constants for the input (used in the transition table)
ad 3: the transition table for the state machine
ad 4: test if we are in a parseContinue() step
a) if no, do inititalizations
b) if yes, restore the state and call parse functions recursively
ad 5: Do some actions according to the state; from the logical execution
order, this code belongs after 8 (see there for an explanation)
ad 6: Check the character that is at the actual "cursor" position:
a) If we reached the EOF, report either error or push the state (in the
case of incremental parsing).
b) Otherwise, set the input character constant for the transition
table.
ad 7: Get the new state according to the input that was read.
ad 8: Do some actions according to the state. The last line in every case
statement reads new data (i.e. it move the cursor). This can also be
done by calling another parse...() funtion. If you need processing for
this state after that, you have to put it into the switch statement 5.
This ensures that you have a well defined re-entry point, when you ran
out of data.
