/*
2
* parser.c : an XML 1.0 parser, namespaces and validity support are mostly
3
* implemented on top of the SAX interfaces
4
*
5
* References:
6
* The XML specification:
7
* http://www.w3.org/TR/REC-xml
8
* Original 1.0 version:
9
* http://www.w3.org/TR/1998/REC-xml-19980210
10
* XML second edition working draft
11
* http://www.w3.org/TR/2000/WD-xml-2e-20000814
12
*
13
* Okay this is a big file, the parser core is around 7000 lines, then it
14
* is followed by the progressive parser top routines, then the various
15
* high level APIs to call the parser and a few miscellaneous functions.
16
* A number of helper functions and deprecated ones have been moved to
17
* parserInternals.c to reduce this file size.
18
* As much as possible the functions are associated with their relative
19
* production in the XML specification. A few productions defining the
20
* different ranges of character are actually implanted either in
21
* parserInternals.h or parserInternals.c
22
* The DOM tree build is realized from the default SAX callbacks in
23
* the module SAX.c.
24
* The routines doing the validation checks are in valid.c and called either
25
* from the SAX callbacks or as standalone functions using a preparsed
26
* document.

4156
* - a character reference is processed by appending the referenced
4157
* character to the attribute value
4158
* - an entity reference is processed by recursively processing the
4159
* replacement text of the entity
4160
* - a whitespace character (#x20, #xD, #xA, #x9) is processed by
4161
* appending #x20 to the normalized value, except that only a single
4162
* #x20 is appended for a "#xD#xA" sequence that is part of an external
4163
* parsed entity or the literal entity value of an internal parsed entity
4164
* - other characters are processed by appending them to the normalized value
4165
* If the declared value is not CDATA, then the XML processor must further
4166
* process the normalized attribute value by discarding any leading and
4167
* trailing space (#x20) characters, and by replacing sequences of space
4168
* (#x20) characters by a single space (#x20) character.
4169
* All attributes for which no declaration has been read should be treated
4170
* by a non-validating parser as if declared CDATA.
4171
*
4172
* Returns the AttValue parsed or NULL. The value has to be freed by the caller.

8879
* 3.3.3 Attribute-Value Normalization:
8880
* Before the value of an attribute is passed to the application or
8881
* checked for validity, the XML processor must normalize it as follows:
8882
* - a character reference is processed by appending the referenced
8883
* character to the attribute value
8884
* - an entity reference is processed by recursively processing the
8885
* replacement text of the entity
8886
* - a whitespace character (#x20, #xD, #xA, #x9) is processed by
8887
* appending #x20 to the normalized value, except that only a single
8888
* #x20 is appended for a "#xD#xA" sequence that is part of an external
8889
* parsed entity or the literal entity value of an internal parsed entity
8890
* - other characters are processed by appending them to the normalized value
8891
* If the declared value is not CDATA, then the XML processor must further
8892
* process the normalized attribute value by discarding any leading and
8893
* trailing space (#x20) characters, and by replacing sequences of space
8894
* (#x20) characters by a single space (#x20) character.
8895
* All attributes for which no declaration has been read should be treated
8896
* by a non-validating parser as if declared CDATA.
8897
*
8898
* Returns the AttValue parsed or NULL. The value has to be freed by the
8899
* caller if it was copied, this can be detected by val[*len] == 0.
