See here for details on how to make a case insensitive string type:
http://www.gotw.ca/gotw/029.htm

You can then specialise the property tree with this new type:

typedef basic_ptree< ci_string, std::string > ptree;

You can also use boost::iequals for comparing strings ignoring case,
which may or may not be a better solution depending on your
requirements.Regards
