Excerpt of article text...
Unless your idea of computer programming still involves punch cards, you've at least heard of XML (eXtensible Markup Language). However, you may not have had a chance to use it much, or know how it can be used. Or perhaps you know something about XML but REALbasic's complex XML classes are bewildering. Either way, this article's going to be a gentle introduction to RB's XML classes. I don't claim to be an XML expert, but I am excited about using XML with REALbasic.
What Is XML?
Like HTML, the language of the Web, XML is a language of special tags enclosed within greater- and less-than brackets (<>).

For instance, HTML's <b> indicates the text following it should be bold.
In contrast, XML tags are not pre-defined* -- you're free to make up whatever tags you need -- and XML tags don't indicate formatting, only the type of content. Examples of XML tags might be <Address> or <CD_Title>.
