2. XSLT Extensible Stylesheet Language Transformations XSLT is used for converting XML to some other output or restructuring XML XSLT utilizes XPath XSLT is a declarative language, written in XML

3. Original XML document In memory Source tree + In memory Result tree XSL Template XSLT Transformation Process Serialization Target Document

4. Foundational XSLT Elements XSLT is writing in XML, the root element of XSLT is or contains template for the output tell the XSLT processor to apply specific template to specific node of the source tree

5. Source tree info. extraction : provides the value of a part of the source tree that represents the source XML document. : copies a node to the result tree, but it doesn’t copy any descendant nodes or attributes : a deep copy (a node, together with all its attribute nodes and descendant nodes, is copied to the result tree)

6. Adding child element/attribute : add new attribute to the context node in the result tree : add child node to the context node in the result tree

36. David Hunter Danny Ayers Jeff Rafter John Duckett Eric van der Vlist Andrew Watt Joe Fawcett 2007 XML is a markup language, derived from SGML. To be well-formed an XML document must satisfy several rules about its structure. To help unambiguously identify the names of elements and attributes the notion of an XML namespace is used. A document type definition, DTD, is a way to specify the permitted structure of an XML document. W3C XML Schema and Relax NG are two schema languages to specify the structure of XML documents.
