A MIME`ParseSet` associates simple and regex MIME header tokens with parsers. Regex tokens are stored in a list, while simple tokens are stored in a hashed list for quick access.

This module is implemented by HTMIMPrs.c, and it is a part of the W3C Reference Library.

    #define HTMIMPRS_H

    #include "HTHeader.h"

## Data Types

The HTMIMEParseSet contains all registered MIME parses. There are regex parsers, which are stored in a list of HTMIMEParseEl, and simple (no wildcards) parsers stored in a hashed array of lists of HTMIMEParseEl.

    typedef struct _HTMIMEParseEl HTMIMEParseEl;

    #define HT_MAX_NO_CACHE		9     /* Number of headers to exclude */

    struct _HTMIMEParseSet {
        int size;
        HTMIMEParseEl ** parsers;
        HTMIMEParseEl * regexParsers;
        int no_cache[HT_MAX_NO_CACHE];
    };

    #define MIMEParseSet_NULL {0, NULL, NULL}

## Public Functions

The following methods are available for this HTMIMEParseSets:

### Create and destroy`HashLists`

    extern HTMIMEParseSet * HTMIMEParseSet_new(int hashSize);
    extern HTMIMEParseSet_deleteAll (HTMIMEParseSet * me);

### Add and remove parsers

Register a Header parser to be called if we encounter the token in the protocol response. Tokens can contain a wildcard '*' which will match zero or more arbritary chars.

    extern HTMIMEParseEl * HTMIMEParseSet_add (HTMIMEParseSet * me,
    					   const char * token,
    					   BOOL caseSensitive,
    					   HTParserCallback * callback);
    extern HTMIMEParseEl * HTMIMEParseSet_addRegex (HTMIMEParseSet * me,
    						const char * token,
    						BOOL caseSensitive,
    						HTParserCallback * callback);
    extern int HTMIMEParseSet_delete (HTMIMEParseSet * me, const char * token);

### Execute these parsers

Find `HTParserCallback` which matches the string.

    extern int HTMIMEParseSet_dispatch (HTMIMEParseSet * me, HTRequest * request,
    				    char * token, char * value, BOOL * pFound,
                                        BOOL CacheFilter);
