Professional Xsl (Programmer to Programmer)

XML is now the established standard for platform-neutral data storage and exchange, separating content from presentation. Its popularity is due to the flexibility of the language and the ability to reuse the data in a variety of ways. XSL is a key technology for working with XML, and is comprised of two parts: XSLT is the official language for transforming XML from one format to another, whether for restructuring/selectively processing the data or presenting the data for display; XSL-FO is a proposed vocabulary for incorporating information concerning how the document should be arranged for presentation. A related standard, XPath, is the language for addressing specific parts of an XML document.
