| 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 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. |

| 222 | * CUR_CHAR(l) returns the current unicode character (int), set l |
| 223 | * to the number of xmlChars used for the encoding [0-5]. |

| 2094 | * character to the attribute value |
| 2095 | * - an entity reference is processed by recursively processing the |
| 2096 | * replacement text of the entity |
| 2097 | * - a whitespace character (#x20, #xD, #xA, #x9) is processed by |
| 2098 | * appending #x20 to the normalized value, except that only a single |
| 2099 | * #x20 is appended for a "#xD#xA" sequence that is part of an external |
| 2100 | * parsed entity or the literal entity value of an internal parsed entity |
| 2101 | * - other characters are processed by appending them to the normalized value |
| 2102 | * If the declared value is not CDATA, then the XML processor must further |
| 2103 | * process the normalized attribute value by discarding any leading and |
| 2104 | * trailing space (#x20) characters, and by replacing sequences of space |
| 2105 | * (#x20) characters by a single space (#x20) character. |
| 2106 | * All attributes for which no declaration has been read should be treated |
| 2107 | * by a non-validating parser as if declared CDATA. |
