XML, or Extensible Markup Language, is an increasingly popular cross-platform document processing standard. Created as a scaled-down version of the older SGML, XML is a highly efficient and flexible markup language. That very efficiency has led some to suggest that the meta-language in question could replace HTML as the markup language of choice for formatting dynamic online content.

Below, you will find an active library of XML code samples and tutorials designed to teach web developers the ins and outs of the standard in a very practical fashion. Have fun!
