#define HTMLParser_H__
13
// This class is a simple HTML parser, that is being fed with buffer chunks.
14
// Result is a series of events (virtual method calls) that signalize
15
// occurence of HTML entites like: tag, tag ending, comment or ordinary text in the stream
17
// In order to use this parser, you must inherit this class and override its event handlers
18
// to perform custom processing of HTML parse events.
20
// Additionally, this class offers two methods for escaping and unescaping of some special
21
// characters (for example char '<' is "escaped" to string "<" when saving HTML document to file)
22
// These methods rely on internal character conversion table, sorted by numerical value
23
// of the character, in order to speed up algorithm by using binary-search on the table.
24
// Characters are UTF-8, and they can be multibyte - more than one byte long.
