from manual of re module

M 
MULTILINE
When specified, the pattern character "^" matches at the beginning of
the string and at the beginning of each line (immediately following each
newline); and the pattern character "$" matches at the end of the string
and at the end of each line (immediately preceding each newline). By
default, "^" matches only at the beginning of the string, and "$" only
at the end of the string and immediately before the newline (if any) at
the end of the string. 

S 
DOTALL
Make the "." special character match any character at all, including a
newline; without this flag, "." will match anything except a newline.

anyway, if you cannot get it done by yourself, you can put it in the
mail-list, and we can help you.

使用了一下，感觉不错。
但还是不知道怎么完成多行匹配，即要匹配的模式可能在一行上也可能在多行上，
而且分行的位置不是很确定。
