Note that there is an asymmetry in this library. prefix() does not
426
return the default "" prefix, even if you have declared one; to
427
check for a default prefix, you must look it up explicitly using
428
uri(). This asymmetry exists to make it easier to look up prefixes

for attribute names, where the default prefix is not allowed.

902
903
All subclasses of QXmlReader read the input XML document from this
904
class.
905
906
This class recognizes the encoding of the data by reading the
907
encoding declaration in the XML file if it finds one, and reading
908
the data using the corresponding encoding. If it does not find an
909
encoding declaration, then it assumes that the data is either in
910
UTF-8 or UTF-16, depending on whether it can find a byte-order
911
mark.
912
913
There are two ways to populate the input source with data: you can
914
construct it with a QIODevice* so that the input source reads the
915
data from that device. Or you can set the data explicitly with one
916
of the setData() functions.
917
918
Usually you either construct a QXmlInputSource that works on a
919
QIODevice* or you construct an empty QXmlInputSource and set the
920
data with setData(). There are only rare occasions where you would
921
want to mix both methods.
922
923
The QXmlReader subclasses use the next() function to read the
924
input character by character. If you want to start from the
925
beginning again, use reset().
926
927
The functions data() and fetchData() are useful if you want to do
928
something with the data other than parsing, e.g. displaying the
929
raw XML file. The benefit of using the QXmlInputClass in such
930
cases is that it tries to use the correct encoding.

\class QXmlContentHandler qxml.h

\reentrant
1209
\brief The QXmlContentHandler class provides an interface to
1210
report the logical content of XML data.
1211
\if defined(commercial)
1212
It is part of the <a href="commercialeditions.html">Qt Enterprise Edition</a>.

1217
1218
If the application needs to be informed of basic parsing events,
1219
it can implement this interface and activate it using
1220
QXmlReader::setContentHandler(). The reader can then report basic
1221
document-related events like the start and end of elements and
1222
character data through this interface.
1223
1224
The order of events in this interface is very important, and
1225
mirrors the order of information in the document itself. For
1226
example, all of an element's content (character data, processing
1227
instructions, and sub-elements) appears, in order, between the
1228
startElement() event and the corresponding endElement() event.
1229
1230
The class QXmlDefaultHandler provides a default implementation for
1231
this interface; subclassing from the QXmlDefaultHandler class is
1232
very convenient if you only want to be informed of some parsing
1233
events.
1234
1235
The startDocument() function is called at the start of the
1236
document, and endDocument() is called at the end. Before parsing
1237
begins setDocumentLocator() is called. For each element
1238
startElement() is called, with endElement() being called at the
1239
end of each element. The characters() function is called with
1240
chunks of character data; ignorableWhitespace() is called with
1241
chunks of whitespace and processingInstruction() is called with
1242
processing instructions. If an entity is skipped skippedEntity()
1243
is called. At the beginning of prefix-URI scopes
1244
startPrefixMapping() is called.

The reader calls this function to signal the begin of a prefix-URI
1299
namespace mapping scope. This information is not necessary for
1300
normal namespace processing since the reader automatically
1301
replaces prefixes for element and attribute names.
1302
1303
Note that startPrefixMapping() and endPrefixMapping() calls are
1304
not guaranteed to be properly nested relative to each other: all
1305
startPrefixMapping() events occur before the corresponding

The reader calls this function when it has parsed a start element
1341
tag.
1342
1343
There is a corresponding endElement() call when the corresponding
1344
end element tag is read. The startElement() and endElement() calls
1345
are always nested correctly. Empty element tags (e.g. \c{<x/>})
1346
cause a startElement() call to be immediately followed by an
1347
endElement() call.
1348
1349
The attribute list provided only contains attributes with explicit
1350
values. The attribute list contains attributes used for namespace
1351
declaration (i.e. attributes starting with xmlns) only if the
1352
namespace-prefix property of the reader is TRUE.
1353
1354
The argument \a namespaceURI is the namespace URI, or
1355
QString::null if the element has no namespace URI or if no
1356
namespace processing is done. \a localName is the local name
1357
(without prefix), or QString::null if no namespace processing is

\class QXmlReader qxml.h

\reentrant
2345
\brief The QXmlReader class provides an interface for XML readers (i.e.
2346
parsers).
2347
\if defined(commercial)

\module XML
2352
\ingroup xml-tools
2353
2354
This abstract class provides an interface for all of Qt's XML
2355
readers. Currently there is only one implementation of a reader
2356
included in Qt's XML module: QXmlSimpleReader. In future releases
2357
there might be more readers with different properties available
2358
(e.g. a validating parser).
2359
2360
The design of the XML classes follows the \link
2361
http://www.saxproject.org/ SAX2 Java interface\endlink, with
2362
the names adapted to fit Qt naming conventions. It should be very
2363
easy for anybody who has worked with SAX2 to get started with the
2364
Qt XML classes.
2365
2366
All readers use the class QXmlInputSource to read the input
2367
document. Since you are normally interested in particular content
2368
in the XML document, the reader reports the content through
2369
special handler classes (QXmlDTDHandler, QXmlDeclHandler,
2370
QXmlContentHandler, QXmlEntityResolver, QXmlErrorHandler and
2371
QXmlLexicalHandler), which you must subclass, if you want to
2372
process the contents.
2373
2374
Since the handler classes only describe interfaces you must
2375
implement all the functions. We provide the QXmlDefaultHandler
2376
class to make this easier: it implements a default behaviour (do
2377
nothing) for all functions, so you can subclass it and just
2378
implement the functions you are interested in.
2379
2380
Features and properties of the reader can be set with setFeature()
2381
and setProperty() respectively. You can set the reader to use your
2382
own subclasses with setEntityResolver(), setDTDHandler(),
2383
setContentHandler(), setErrorHandler(), setLexicalHandler() and
2384
setDeclHandler(). The parse itself is started with a call to
2385
parse().

If \a incremental is TRUE, the parser does not return FALSE when
2841
it reaches the end of the \a input without reaching the end of the
2842
XML file. Instead it stores the state of the parser so that
2843
parsing can be continued at a later stage when more data is
2844
available. You can use the function parseContinue() to continue
2845
with parsing. This class stores a pointer to the input source \a

input and the parseContinue() function tries to read from that
2847
input souce. This means that you should not delete the input

source \a input until you've finished your calls to
2849
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.

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

For the incremental parsing, it is very important that the parse...()

3028

3031
3032

Explanation:
3039
ad 1: constants for the states (used in the transition table)
3040
ad 2: constants for the input (used in the transition table)
3041
ad 3: the transition table for the state machine
3042
ad 4: test if we are in a parseContinue() step
3043
a) if no, do inititalizations
3044
b) if yes, restore the state and call parse functions recursively
3045
ad 5: Do some actions according to the state; from the logical execution
3046
order, this code belongs after 8 (see there for an explanation)
3047
ad 6: Check the character that is at the actual "cursor" position:
3048
a) If we reached the EOF, report either error or push the state (in the
3049
case of incremental parsing).
3050
b) Otherwise, set the input character constant for the transition
3051
table.
3052
ad 7: Get the new state according to the input that was read.
3053
ad 8: Do some actions according to the state. The last line in every case
3054
statement reads new data (i.e. it move the cursor). This can also be
3055
done by calling another parse...() funtion. If you need processing for
3056
this state after that, you have to put it into the switch statement 5.
3057
This ensures that you have a well defined re-entry point, when you ran
3058
out of data.
