Review: SAMS Teach Yourself XML in 21 Days
I highly recommend this textbook. Provides practical insights into the XML programming language, how resourceful it can be if used along other OOP, or
procedural based programming languages like C, C#, C++, Java, Python, Perl, Ruby, and Gnu gcc, 'go-to web application/software dev languages'. Would be most useful if used as a supplemental resource parallel to introductory source code programming concepts like fundamental video game or simulator development programming. Contains no UR code to download contents to tablet or smartphone.
