regex_match doesn't match in an embedded string

17 Jan 2002

      Hi there,

not sure how I could write that Subject line. Sorry :-)

Here's the thing, I have a file with the following:

KEY1 = ${short_localhost}
KEY2 = bbbf<control2.cfg:OTHER_SECTION:${long_localhost}>aaaf:<he

I need to extract the value between the {} when it starts with a $.
My expression works ok for KEY1 (the value part, the string to the 
right
of the equal sign), however it doesn't match for the value for KEY2.

This is what I have:

static const boost::regex expression( "\\$\\{(.*?)\\}" );
boost::cmatch what;
if ( boost::regex_match( input, what, expression ) )
{
  cerr << "GOT IT!" << endl;
}
else
{
  cerr << "NOPE" << endl;
}

where input is a std::string with the value described above.

Why does it work for KEY1 and not KEY2?

Interestingly enough, if I do the following:

KEY1 = dd${short_localhost}

it doesn't match either.

This same expression in Perl works fine though.

thanks,
