2012-09-25 XML Basics: The Extensible Markup Language (XML) defines a simple way for structuring data. The power and popularity of XML can be explained by its versatility, the platform-independence, the standards and technologies leveraging it, and the number of tools and products supporting it. Understanding XML itself is rather simple, it only depends on a very small set of other technologies. Unicode and URIs are the most important foundations of XML. XML itself specifies two different things: on the one hand the format for structured data, which are called XML documents, and on the other hand a constraint language for XML documents, which is called Document Type Definition (DTD).

2012-09-27 XML Path Language (XPath): XML structures data into a rather small number of different constructs, most notably elements and attributes. The XML Path Language (XPath) defines a way how to select parts of XML documents, so that they can be used for further processing. XPath is a very compact language with a syntax that resembles path expressions well-known from file systems. These path expressions, however, are generalized and therefore much more powerful than the rather simple path expressions in file systems. Because of its use in different XML technologies, XPath is one of the most important XML core technologies. With XPath 2.0, the language has been greatly extended, the new version of XPath is the foundation for XSLT 2.0 and XQuery. XPath 2.0 provides support for regular expression matching, typed expressions, and contains language constructs for conditional and repeated evaluation.
