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.

3264 | * #x20 is appended for a "#xD#xA" sequence that is part of an external

3265 | * parsed entity or the literal entity value of an internal parsed entity
|

3266 | * - other characters are processed by appending them to the normalized value
|
---|
3267 | * If the declared value is not CDATA, then the XML processor must further
|

3268 | * process the normalized attribute value by discarding any leading and
|
---|
3269 | * trailing space (#x20) characters, and by replacing sequences of space

|

7648 | * - a whitespace character (#x20, #xD, #xA, #x9) is processed by
|
---|
7649 | * appending #x20 to the normalized value, except that only a single
|
---|
7650 | * #x20 is appended for a "#xD#xA" sequence that is part of an external
|
---|
7651 | * parsed entity or the literal entity value of an internal parsed entity
|
---|
7652 | * - other characters are processed by appending them to the normalized value
|
---|
7653 | * If the declared value is not CDATA, then the XML processor must further
|
---|
7654 | * process the normalized attribute value by discarding any leading and
|
---|
7655 | * trailing space (#x20) characters, and by replacing sequences of space
|
---|
7656 | * (#x20) characters by a single space (#x20) character.

7657 | * All attributes for which no declaration has been read should be treated
