Strip whitespace from start and end of String

Hi

I need help trying to use regular expression to validate
that there is
no white space at the start and end of a string. Also the
string can
contain spaces, just not at the start and end. Also the
string can be
a single character. Any help will be much appreciated.

I got this far but it does not cater for a single character

namePattern = "((^[A-Z0-9]([A-Z_0-9
]+)?[A-Z0-9]$){1,12})";

Thanks
