reg_assoc() - A regular pattern substring extractor
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
mixed *reg_assoc(string str, string *pat_arr, mixed
*tok_arr, void | mixed def);
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
reg_assoc takes a string and explodes it into substrings
matching the regular expression pattern-strings given in
pat_arr and associates them with tokens given in tok_arr. If
def (default 0) is given, it is associated with a non-match.
The return value is an array of two arrays, the 1st being an
array of the form
({ non-match1, match1, non-match2, match2, ...,
non-match n, match n, non-match n+1 })
and the 2nd holds the tokens corresponding to the matches in
order:
({ def, token corresponding to match1, ...., def,
token corresponding to match n, def }).
pat_arr and tok_arr must be of the same sizes, the ith
element in tok_arr being the corresponding token to the ith
element of pat_arr. pat_arr can only hold strings.
If pat_arr (and hence tok_arr) has size 0 then the return
value is simply ({ ({ str }), ({ def }) }).
