XML otherwise known as Extensible Markup Language is an interesting standard.  Before our last class, all I knew of XML was what it stood for.  I didn't know that it was actually derived from SGML (Standardized General Markup Language) or the fact in how extensively it is used.

From the web sites I manage, I've learned a fair amount of HTML, I wouldn't consider myself an expert on the topic, but I can read the source code on any given web site and usually figure out what's happening.  However, with XML, there really is no deciphering.  The person coding the XML file can create their own tags for everything needed and add the content straight into the XML file.

I also like the fact that XML actually has it's own stylesheet.  I have some slight experience with CSS and that knowledge helped me better understand how the page can change so drastically when the stylesheet is manipulated.

Overall, I think XML is an interesting topic.  Hopefully, I'll get some hands on experience with it in class.
