Sorry, but this strays a little from actual boost.  Since there are a
handful of you that are probably using regex, I was hoping someone could
help with syntax.

I have a regex that validates a latitude format.

 

These are the restrictions:

Must have an N or S as first letter.

It can be all values from 0.0 to 90.0

My first shot at it confirmed format, but not data constraints:
"(N|S)\\d{2}\\.\\d{1,6} <file:///\\d%7b2%7d\d%7b1,6%7d> "

 

 

But any attempts to limit the constraints caused an exception in regex.  Is
there something wrong w/ how I formatted this:
"(N|S)(9[0]\\.0{1-6}|[0-8]\\d\\.\\d{1-6}
<file:///\\.0%7b1-6%7d|[0-8]\d\d%7b1-6%7d> )"

 

To me, it reads:  1st char must be N|S

If second char is 9, the next chars must be 0.0 through 0.000000

Else

If char is 0-8, then the next just has to be digits [0-9].[0-9]{1-6}

 

Can anyone tell me what I am doing wrong?  

Just FYI, I am coding in VS 2005 C++

Thanks
