Review: SAMS Teach Yourself XML and XHTML
I highly recommend this textbook. Provides practical insights into the HTML and XHTML 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 those used for fundamental MS-DOS, CMD, MS Powershell. Contains no UR code to download contents to tablet or smartphone.
