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.

• 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

• 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.
