using regexps with streams

hi

i'm wondering if it's possible to use apply the regex-search algorithm on
an input stream. my first thought is that it's not, since i've read (and
so it looks on the specification) that the regex_search function can be
passed only bi-directional iterators, and as far as i know one can only
create input iterators on streams. typically, the first and second
arguments of regex_search are iterators on the first and (most annoyingly)
last element, which one cannot get with a stream. 

however, there might be (and i hope there is) another way to do it i'm not
aware of. 

thx

David
