Thanks! Here is the regular expression I am using:

Last Trade:.*?([0-9]+\\.[0-9]{2,}).*?Trade Time:

and the part indeed in the test.htm has something like this:

Last Trade:</td><td
class="yfnc_tabledata1"><big><b>73.77</b></big></td></tr><tr><td
class="yfnc_tablehead1" width="48%">Trade Time:</td><td
class="yfnc_tabledata1">Feb 17</td>

So it should be alright to find the match 73.77, right? But as I mentioned
in previous email, expr[1].c_str() always returns an empty string.

The attached is a Visual Studio .Net 2003 or VC71 project that has all you
need to duplicate the problem. You need to copy the test.htm to c:\ before
doing anything. FYI, I am using Regex++ 1.28.0
