XMLs Quirky Namespaces

摘要

Last month, microsoft announced that the forthcoming Office 12 will save to XML by default and that earlier versions will be retrofitted to work with XML. This week Apple released its podcast-aware version of iTunes and defined an extension to RSS 2.0 for use with its online music store. Over the next year or so, these initiatives will create millions of new users of XML. They'll also expose thousands of developers to a feature of XML that's caused more than its fair share of headaches: namespaces. You can perform all kinds of useful XML processing without ever touching a namespace, and many developers do.
