====== XML Technologies ======

This lecture covers XML and the host of technologies associated with it. Using XML tools you should be able to access an XML document, ensure it is well-formed and valid, process it, modify it, transform it, and then save or serve the new XML document.

===== Outline =====

  * Overview of XML
  * Well-formed versus Valid
  * XML Schema: XSD
  * XML Parsers: DOM and SAX
  * XML Transformations
  * XML Style sheets: XSL and XPath
  * XSL and JSP

See {{:xmltech.pdf|}}

===== To Do =====

  * Read Section 9.5
  * Read Chapter 7
  * Look at ''Card*.xml/xsd'' in the //Resource Directory// as processed by programs ''DOM'' and ''Validate''
  * Look at ''Modify'' and ''Tranform'' to see how trivial it is to modify and save XML documents.
  * Look at ''Xslt.java''. It implements the transformation given the xml/xsl pair and produces the output on standard output.
  * Look at the ''S?.xsl'' stylesheets one by one and in order.
  * SS.jspx implements the transformation at the server via JSP.
  * Sf.xsl has the same effect as S3.xsl except it exposes the declarative approach rather than the procedural one.
