[Boost-users] Grep() question

Hello all, I have the following regular expression, but it doesn't match to
this text "REVENUE
...................................................        $10,481.1"

const char* pattern[] = "Revenue[\s\.]*\$?\s*([0-9,\.]*)";

my code looks something like this:

std::vector <unsigned int> v;
boost::RegEx expr(pattern, true);
v.clear();

unsigned int result = expr.Grep(v, pBuf);
if (result != 0) {

    std::string s = expr[0];
    s = expr[1];

............

Why expr[0] and expr[1] weren't return the aboved mention text as the first
match? I think set 'true' in expr constructor means do case insensitve
match.
