Annotation of XML/parser.c, revision 1.242
1.1 veillard 1: /*
1.229 veillard 2: * parser.c : an XML 1.0 parser, namespaces and validity support are mostly
3: * implemented on top of the SAX interfaces
1.15 veillard 4: *
1.222 veillard 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: *
1.229 veillard 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 miscelaneous 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 standalones functions using a preparsed
26: * document.
27: *
