XpointerXPointer is a system for addressing components of XML based internet media. At the present time (late 2002), XPointer is divided among four specifications: a "framework" which forms the basis for indentifying XML fragments, a positional element addressing scheme, a scheme for namespaces, and a scheme for XPath-based addressing. The XPointer language is designed to address structural aspects of XML, including text content and other information objects created as a result of parsing the document. Thus, it could be used to point to a section of a document highlighted by a user through a mouse drag action. Positional Element Addressing The element() scheme introduces positional addressing of child elements. This is similar to a simple XPath address, but subsequent steps can only be numbers representing the position of a descendant relative to its branch on the tree. For instance, given the following fragment <foobar id="foo"><bar/><baz><bom/></baz></foobar> the XPointer to bom would be element(foo/2/1) External links
