XML and command line parsing in C++/C

Dynamic languages like python, tcl or alike are taking over in driving many C/C++ codes I/O operations and option parsing due to quick and easy implementation, however it is still possible to use libraries/APIs for parsing options via command line (or XML ) quite efficiently in C/C++. Here is the list of some API/libraries:

• Xerces is Apache's XML parser for C++.
• GCCXML is gcc extention for XML parsing in C++.
• Commons CLI is Apache's command line parsing API.
• Argtable is ANSI C command line parser.
• getop is gnu's commang line parser.
• tclap is templatized C++ command line parser.
