.. module:: xml.parsers.expat

:synopsis: An interface to the Expat non-validating XML parser.
7
.. moduleauthor:: Paul Prescod <paul@prescod.net>
12
Many of the attributes of the XMLParser objects are callbacks. Since
13
signature information must be presented, these are described using the method
14
directive. Since they are attributes which are set by client code, in-text
15
references to these attributes should be marked using the :member: role.
20
The :mod:`pyexpat` module is not secure against maliciously
21
constructed data. If you need to parse untrusted or unauthenticated data see
22
:ref:`xml-vulnerabilities`.
27
.. index:: single: Expat
29
The :mod:`xml.parsers.expat` module is a Python interface to the Expat
30
non-validating XML parser. The module provides a single extension type,
31
:class:`xmlparser`, that represents the current state of an XML parser. After
32
an :class:`xmlparser` object has been created, various attributes of the object
33
can be set to handler functions. When an XML document is then fed to the
34
parser, the handler functions are called for the character data and markup in
37
.. index:: module: pyexpat
39
This module uses the :mod:`pyexpat` module to provide access to the Expat
40
parser. Direct use of the :mod:`pyexpat` module is deprecated.
42
This module provides one exception and one type object:
45
.. exception:: ExpatError
47
The exception raised when Expat reports an error. See section
48
:ref:`expaterror-objects` for more information on interpreting Expat errors.
53
Alias for :exc:`ExpatError`.
56
.. data:: XMLParserType
58
The type of the return values from the :func:`ParserCreate` function.
60
The :mod:`xml.parsers.expat` module contains two functions:
63
.. function:: ErrorString(errno)
65
Returns an explanatory string for a given error number *errno*.
68
.. function:: ParserCreate([encoding[, namespace_separator]])
70
Creates and returns a new :class:`xmlparser` object. *encoding*, if specified,
71
must be a string naming the encoding used by the XML data. Expat doesn't
72
support as many encodings as Python does, and its repertoire of encodings can't
73
be extended; it supports UTF-8, UTF-16, ISO-8859-1 (Latin1), and ASCII. If
74
*encoding* [1]_ is given it will override the implicit or explicit encoding of the
77
Expat can optionally do XML namespace processing for you, enabled by providing a
78
value for *namespace_separator*. The value must be a one-character string; a
79
:exc:`ValueError` will be raised if the string has an illegal length (``None``
80
is considered the same as omission). When namespace processing is enabled,
81
element type names and attribute names that belong to a namespace will be
82
expanded. The element name passed to the element handlers
83
:attr:`StartElementHandler` and :attr:`EndElementHandler` will be the
84
concatenation of the namespace URI, the namespace separator character, and the
85
local part of the name. If the namespace separator is a zero byte (``chr(0)``)
86
then the namespace URI and the local part will be concatenated without any
89
For example, if *namespace_separator* is set to a space character (``' '``) and
90
the following document is parsed::
93
<root xmlns = "http://default-namespace.org/"
94
xmlns:py = "http://www.python.org/ns/">
99
:attr:`StartElementHandler` will receive the following strings for each
102
http://default-namespace.org/ root
103
http://www.python.org/ns/ elem1
106
Due to limitations in the ``Expat`` library used by :mod:`pyexpat`,
107
the :class:`xmlparser` instance returned can only be used to parse a single
108
XML document. Call ``ParserCreate`` for each document to provide unique

117
.. _xmlparser-objects:
122
:class:`xmlparser` objects have the following methods:
125
.. method:: xmlparser.Parse(data[, isfinal])
127
Parses the contents of the string *data*, calling the appropriate handler
128
functions to process the parsed data. *isfinal* must be true on the final call
129
to this method; it allows the parsing of a single file in fragments,
130
not the submission of multiple files.
131
*data* can be the empty string at any time.
134
.. method:: xmlparser.ParseFile(file)
136
Parse XML data reading from the object *file*. *file* only needs to provide
137
the ``read(nbytes)`` method, returning the empty string when there's no more
141
.. method:: xmlparser.SetBase(base)
143
Sets the base to be used for resolving relative URIs in system identifiers in
144
declarations. Resolving relative identifiers is left to the application: this
145
value will be passed through as the *base* argument to the
146
:func:`ExternalEntityRefHandler`, :func:`NotationDeclHandler`, and
147
:func:`UnparsedEntityDeclHandler` functions.
150
.. method:: xmlparser.GetBase()
152
Returns a string containing the base set by a previous call to :meth:`SetBase`,
153
or ``None`` if :meth:`SetBase` hasn't been called.
156
.. method:: xmlparser.GetInputContext()
158
Returns the input data that generated the current event as a string. The data is
159
in the encoding of the entity which contains the text. When called while an
160
event handler is not active, the return value is ``None``.
162
.. versionadded:: 2.1
165
.. method:: xmlparser.ExternalEntityParserCreate(context[, encoding])
167
Create a "child" parser which can be used to parse an external parsed entity
168
referred to by content parsed by the parent parser. The *context* parameter
169
should be the string passed to the :meth:`ExternalEntityRefHandler` handler
170
function, described below. The child parser is created with the
171
:attr:`ordered_attributes`, :attr:`returns_unicode` and
172
:attr:`specified_attributes` set to the values of this parser.
174
.. method:: xmlparser.SetParamEntityParsing(flag)
176
Control parsing of parameter entities (including the external DTD subset).
177
Possible *flag* values are :const:`XML_PARAM_ENTITY_PARSING_NEVER`,
178
:const:`XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE` and
179
:const:`XML_PARAM_ENTITY_PARSING_ALWAYS`. Return true if setting the flag
182
.. method:: xmlparser.UseForeignDTD([flag])
184
Calling this with a true value for *flag* (the default) will cause Expat to call
185
the :attr:`ExternalEntityRefHandler` with :const:`None` for all arguments to
186
allow an alternate DTD to be loaded. If the document does not contain a
187
document type declaration, the :attr:`ExternalEntityRefHandler` will still be
188
called, but the :attr:`StartDoctypeDeclHandler` and
189
:attr:`EndDoctypeDeclHandler` will not be called.
191
Passing a false value for *flag* will cancel a previous call that passed a true
192
value, but otherwise has no effect.
194
This method can only be called before the :meth:`Parse` or :meth:`ParseFile`
195
methods are called; calling it after either of those have been called causes
196
:exc:`ExpatError` to be raised with the :attr:`code` attribute set to
197
:const:`errors.XML_ERROR_CANT_CHANGE_FEATURE_ONCE_PARSING`.
199
.. versionadded:: 2.3
201
:class:`xmlparser` objects have the following attributes:
204
.. attribute:: xmlparser.buffer_size
206
The size of the buffer used when :attr:`buffer_text` is true.
207
A new buffer size can be set by assigning a new integer value
209
When the size is changed, the buffer will be flushed.
211
.. versionadded:: 2.3
213
.. versionchanged:: 2.6
214
The buffer size can now be changed.
216
.. attribute:: xmlparser.buffer_text
218
Setting this to true causes the :class:`xmlparser` object to buffer textual
219
content returned by Expat to avoid multiple calls to the
220
:meth:`CharacterDataHandler` callback whenever possible. This can improve
221
performance substantially since Expat normally breaks character data into chunks
222
at every line ending. This attribute is false by default, and may be changed at
225
.. versionadded:: 2.3
228
.. attribute:: xmlparser.buffer_used
230
If :attr:`buffer_text` is enabled, the number of bytes stored in the buffer.
231
These bytes represent UTF-8 encoded text. This attribute has no meaningful
232
interpretation when :attr:`buffer_text` is false.
234
.. versionadded:: 2.3
237
.. attribute:: xmlparser.ordered_attributes
239
Setting this attribute to a non-zero integer causes the attributes to be
240
reported as a list rather than a dictionary. The attributes are presented in
241
the order found in the document text. For each attribute, two list entries are
242
presented: the attribute name and the attribute value. (Older versions of this
243
module also used this format.) By default, this attribute is false; it may be
246
.. versionadded:: 2.1
249
.. attribute:: xmlparser.returns_unicode
251
If this attribute is set to a non-zero integer, the handler functions will be
252
passed Unicode strings. If :attr:`returns_unicode` is :const:`False`, 8-bit
253
strings containing UTF-8 encoded data will be passed to the handlers. This is
254
:const:`True` by default when Python is built with Unicode support.
256
.. versionchanged:: 1.6
257
Can be changed at any time to affect the result type.
260
.. attribute:: xmlparser.specified_attributes
262
If set to a non-zero integer, the parser will report only those attributes which
263
were specified in the document instance and not those which were derived from
264
attribute declarations. Applications which set this need to be especially
265
careful to use what additional information is available from the declarations as
266
needed to comply with the standards for the behavior of XML processors. By
267
default, this attribute is false; it may be changed at any time.
269
.. versionadded:: 2.1
271
The following attributes contain values relating to the most recent error
272
encountered by an :class:`xmlparser` object, and will only have correct values
273
once a call to :meth:`Parse` or :meth:`ParseFile` has raised a
274
:exc:`xml.parsers.expat.ExpatError` exception.
277
.. attribute:: xmlparser.ErrorByteIndex
279
Byte index at which an error occurred.
282
.. attribute:: xmlparser.ErrorCode
284
Numeric code specifying the problem. This value can be passed to the
285
:func:`ErrorString` function, or compared to one of the constants defined in the
289
.. attribute:: xmlparser.ErrorColumnNumber
291
Column number at which an error occurred.
294
.. attribute:: xmlparser.ErrorLineNumber
296
Line number at which an error occurred.
298
The following attributes contain values relating to the current parse location
299
in an :class:`xmlparser` object. During a callback reporting a parse event they
300
indicate the location of the first of the sequence of characters that generated
301
the event. When called outside of a callback, the position indicated will be
302
just past the last parse event (regardless of whether there was an associated
305
.. versionadded:: 2.4
308
.. attribute:: xmlparser.CurrentByteIndex
310
Current byte index in the parser input.
313
.. attribute:: xmlparser.CurrentColumnNumber
315
Current column number in the parser input.
318
.. attribute:: xmlparser.CurrentLineNumber
320
Current line number in the parser input.
322
Here is the list of handlers that can be set. To set a handler on an
323
:class:`xmlparser` object *o*, use ``o.handlername = func``. *handlername* must
324
be taken from the following list, and *func* must be a callable object accepting
325
the correct number of arguments. The arguments are all strings, unless
329
.. method:: xmlparser.XmlDeclHandler(version, encoding, standalone)
331
Called when the XML declaration is parsed. The XML declaration is the
332
(optional) declaration of the applicable version of the XML recommendation, the
333
encoding of the document text, and an optional "standalone" declaration.
334
*version* and *encoding* will be strings of the type dictated by the
335
:attr:`returns_unicode` attribute, and *standalone* will be ``1`` if the
336
document is declared standalone, ``0`` if it is declared not to be standalone,
337
or ``-1`` if the standalone clause was omitted. This is only available with
338
Expat version 1.95.0 or newer.
340
.. versionadded:: 2.1
343
.. method:: xmlparser.StartDoctypeDeclHandler(doctypeName, systemId, publicId, has_internal_subset)
345
Called when Expat begins parsing the document type declaration (``<!DOCTYPE
346
...``). The *doctypeName* is provided exactly as presented. The *systemId* and
347
*publicId* parameters give the system and public identifiers if specified, or
348
``None`` if omitted. *has_internal_subset* will be true if the document
349
contains and internal document declaration subset. This requires Expat version
353
.. method:: xmlparser.EndDoctypeDeclHandler()
355
Called when Expat is done parsing the document type declaration. This requires
356
Expat version 1.2 or newer.
359
.. method:: xmlparser.ElementDeclHandler(name, model)
361
Called once for each element type declaration. *name* is the name of the
362
element type, and *model* is a representation of the content model.
365
.. method:: xmlparser.AttlistDeclHandler(elname, attname, type, default, required)
367
Called for each declared attribute for an element type. If an attribute list
368
declaration declares three attributes, this handler is called three times, once
369
for each attribute. *elname* is the name of the element to which the
370
declaration applies and *attname* is the name of the attribute declared. The
371
attribute type is a string passed as *type*; the possible values are
372
``'CDATA'``, ``'ID'``, ``'IDREF'``, ... *default* gives the default value for
373
the attribute used when the attribute is not specified by the document instance,
374
or ``None`` if there is no default value (``#IMPLIED`` values). If the
375
attribute is required to be given in the document instance, *required* will be
376
true. This requires Expat version 1.95.0 or newer.
379
.. method:: xmlparser.StartElementHandler(name, attributes)
381
Called for the start of every element. *name* is a string containing the
382
element name, and *attributes* is a dictionary mapping attribute names to their
386
.. method:: xmlparser.EndElementHandler(name)
388
Called for the end of every element.
391
.. method:: xmlparser.ProcessingInstructionHandler(target, data)
393
Called for every processing instruction.
396
.. method:: xmlparser.CharacterDataHandler(data)
398
Called for character data. This will be called for normal character data, CDATA
399
marked content, and ignorable whitespace. Applications which must distinguish
400
these cases can use the :attr:`StartCdataSectionHandler`,
401
:attr:`EndCdataSectionHandler`, and :attr:`ElementDeclHandler` callbacks to
402
collect the required information.
405
.. method:: xmlparser.UnparsedEntityDeclHandler(entityName, base, systemId, publicId, notationName)
407
Called for unparsed (NDATA) entity declarations. This is only present for
408
version 1.2 of the Expat library; for more recent versions, use
409
:attr:`EntityDeclHandler` instead. (The underlying function in the Expat
410
library has been declared obsolete.)
413
.. method:: xmlparser.EntityDeclHandler(entityName, is_parameter_entity, value, base, systemId, publicId, notationName)
415
Called for all entity declarations. For parameter and internal entities,
416
*value* will be a string giving the declared contents of the entity; this will
417
be ``None`` for external entities. The *notationName* parameter will be
418
``None`` for parsed entities, and the name of the notation for unparsed
419
entities. *is_parameter_entity* will be true if the entity is a parameter entity
420
or false for general entities (most applications only need to be concerned with
421
general entities). This is only available starting with version 1.95.0 of the
424
.. versionadded:: 2.1
427
.. method:: xmlparser.NotationDeclHandler(notationName, base, systemId, publicId)
429
Called for notation declarations. *notationName*, *base*, and *systemId*, and
430
*publicId* are strings if given. If the public identifier is omitted,
431
*publicId* will be ``None``.
434
.. method:: xmlparser.StartNamespaceDeclHandler(prefix, uri)
436
Called when an element contains a namespace declaration. Namespace declarations
437
are processed before the :attr:`StartElementHandler` is called for the element
438
on which declarations are placed.
441
.. method:: xmlparser.EndNamespaceDeclHandler(prefix)
443
Called when the closing tag is reached for an element that contained a
444
namespace declaration. This is called once for each namespace declaration on
445
the element in the reverse of the order for which the
446
:attr:`StartNamespaceDeclHandler` was called to indicate the start of each
447
namespace declaration's scope. Calls to this handler are made after the
448
corresponding :attr:`EndElementHandler` for the end of the element.
451
.. method:: xmlparser.CommentHandler(data)
453
Called for comments. *data* is the text of the comment, excluding the leading
454
``'<!-``\ ``-'`` and trailing ``'-``\ ``->'``.
457
.. method:: xmlparser.StartCdataSectionHandler()
459
Called at the start of a CDATA section. This and :attr:`EndCdataSectionHandler`
460
are needed to be able to identify the syntactical start and end for CDATA
464
.. method:: xmlparser.EndCdataSectionHandler()
466
Called at the end of a CDATA section.
469
.. method:: xmlparser.DefaultHandler(data)
471
Called for any characters in the XML document for which no applicable handler
472
has been specified. This means characters that are part of a construct which
473
could be reported, but for which no handler has been supplied.
476
.. method:: xmlparser.DefaultHandlerExpand(data)
478
This is the same as the :func:`DefaultHandler`, but doesn't inhibit expansion
479
of internal entities. The entity reference will not be passed to the default
483
.. method:: xmlparser.NotStandaloneHandler()
485
Called if the XML document hasn't been declared as being a standalone document.
486
This happens when there is an external subset or a reference to a parameter
487
entity, but the XML declaration does not set standalone to ``yes`` in an XML
488
declaration. If this handler returns ``0``, then the parser will raise an
489
:const:`XML_ERROR_NOT_STANDALONE` error. If this handler is not set, no
490
exception is raised by the parser for this condition.
493
.. method:: xmlparser.ExternalEntityRefHandler(context, base, systemId, publicId)
495
Called for references to external entities. *base* is the current base, as set
496
by a previous call to :meth:`SetBase`. The public and system identifiers,
497
*systemId* and *publicId*, are strings if given; if the public identifier is not
498
given, *publicId* will be ``None``. The *context* value is opaque and should
499
only be used as described below.
501
For external entities to be parsed, this handler must be implemented. It is
502
responsible for creating the sub-parser using
503
``ExternalEntityParserCreate(context)``, initializing it with the appropriate
504
callbacks, and parsing the entity. This handler should return an integer; if it
505
returns ``0``, the parser will raise an
506
:const:`XML_ERROR_EXTERNAL_ENTITY_HANDLING` error, otherwise parsing will
509
If this handler is not provided, external entities are reported by the
510
:attr:`DefaultHandler` callback, if provided.

ExpatError Exceptions
516
---------------------
518
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
521
:exc:`ExpatError` exceptions have a number of interesting attributes:
524
.. attribute:: ExpatError.code
526
Expat's internal error number for the specific error. This will match one of
527
the constants defined in the ``errors`` object from this module.
529
.. versionadded:: 2.1
532
.. attribute:: ExpatError.lineno
534
Line number on which the error was detected. The first line is numbered ``1``.
536
.. versionadded:: 2.1
539
.. attribute:: ExpatError.offset
541
Character offset into the line where the error occurred. The first column is

592
Content Model Descriptions
593
--------------------------
595
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
598
Content modules are described using nested tuples. Each tuple contains four
599
values: the type, the quantifier, the name, and a tuple of children. Children
600
are simply additional content module descriptions.
602
The values of the first two fields are constants defined in the ``model`` object
603
of the :mod:`xml.parsers.expat` module. These constants can be collected in two
604
groups: the model type group and the quantifier group.
606
The constants in the model type group are:
609
.. data:: XML_CTYPE_ANY
612
The element named by the model name was declared to have a content model of
616
.. data:: XML_CTYPE_CHOICE
619
The named element allows a choice from a number of options; this is used for
620
content models such as ``(A | B | C)``.
623
.. data:: XML_CTYPE_EMPTY
626
Elements which are declared to be ``EMPTY`` have this model type.
629
.. data:: XML_CTYPE_MIXED
633
.. data:: XML_CTYPE_NAME
637
.. data:: XML_CTYPE_SEQ
640
Models which represent a series of models which follow one after the other are
641
indicated with this model type. This is used for models such as ``(A, B, C)``.
643
The constants in the quantifier group are:
646
.. data:: XML_CQUANT_NONE
649
No modifier is given, so it can appear exactly once, as for ``A``.
652
.. data:: XML_CQUANT_OPT
655
The model is optional: it can appear once or not at all, as for ``A?``.
658
.. data:: XML_CQUANT_PLUS
661
The model must occur one or more times (like ``A+``).
664
.. data:: XML_CQUANT_REP
667
The model must occur zero or more times, as for ``A*``.
672
Expat error constants
673
---------------------
675
The following constants are provided in the ``errors`` object of the
676
:mod:`xml.parsers.expat` module. These constants are useful in interpreting
677
some of the attributes of the :exc:`ExpatError` exception objects raised when an
680
The ``errors`` object has the following attributes:
683
.. data:: XML_ERROR_ASYNC_ENTITY
687
.. data:: XML_ERROR_ATTRIBUTE_EXTERNAL_ENTITY_REF
690
An entity reference in an attribute value referred to an external entity instead
691
of an internal entity.
694
.. data:: XML_ERROR_BAD_CHAR_REF
697
A character reference referred to a character which is illegal in XML (for
698
example, character ``0``, or '``�``').
701
.. data:: XML_ERROR_BINARY_ENTITY_REF
704
An entity reference referred to an entity which was declared with a notation, so
708
.. data:: XML_ERROR_DUPLICATE_ATTRIBUTE
711
An attribute was used more than once in a start tag.
714
.. data:: XML_ERROR_INCORRECT_ENCODING
718
.. data:: XML_ERROR_INVALID_TOKEN
721
Raised when an input byte could not properly be assigned to a character; for
722
example, a NUL byte (value ``0``) in a UTF-8 input stream.
725
.. data:: XML_ERROR_JUNK_AFTER_DOC_ELEMENT
728
Something other than whitespace occurred after the document element.
