  12. How to render an XML Document? • Extensible Stylesheet Language (XSL) • Specify how programs should render XML document data • XSL-FO (XSL Formatted Objects) • Vocabulary for specifying formatting • XSLT (XSL Transformation) • Defines rules for transforming one XML documment to another • From Source tree to Result tree • Xpath • Locate parts of the source tree document that match templates defined in the XSL stylesheet Comp Sci 346

  13. <?xml version = "1.0"?> <?xml:stylesheet type = "text/xsl" href = "games.xsl"?> <!-- Fig. 20.28 : games.xml --> <!-- Sports Database --> <sports> <game id = "783"> <name>Cricket</name> <paragraph> Popular in Commonwealth nations. </paragraph> </game> Processing Instruction (PI) references the XSL stylesheet games.xsl Specifies location of XSLT <? ?> delimits a PI target Comp Sci 346

  14. Games.xml continued <game id = "239"> <name>Baseball</name> <paragraph> Popular in America. </paragraph> </game> <game id = "418"> <name>Soccer (Football)</name> <paragraph> Popular sport in the world. </paragraph> </game> </sports> Comp Sci 346

  15. XSL style sheet <?xml version = "1.0"?> <!-- Fig. 20.29 : games.xsl --> <!-- A simple XSLT transformation --> <!-- reference XSL stylesheet URI --> <xsl:stylesheet version = "1.0" xmlns:xsl = "http://www.w3.org/1999/XSL/Transform"> <xsl:output method = "html" omit-xml-declaration = "no" doctype-system = "http://www.w3c.org/TR/xhtml1/DTD/xhtml1-strict.dtd" doctype-public = "-//W3C//DTD XHTML 1.0 Strict//EN"/> <xsl:template match = "/"> <!-- match root element --> Start style sheet Binds namespace xsl to W3C XSLT URI Output as xhtml file. Doctype as xhtml “/” is used to select the root Comp Sci 346

  20. Other applications using XML • DOM • PHP Comp Sci 346

  21. DOM • Document Object Model • Syntax tree for XML document • Tree is passed to application (e.g.browser) • Application can modify the document via the tree • Browser-independent JavaScript functionality Comp Sci 346

  22. Use XML with PHP • XML functionality is based on libxml2 library • Enabled by default on Windows and Linux/Unix • Check for the following with phpinfo() • dom • libxml • simplexml Comp Sci 346

  23. Parsing XML with PHP • Example 1: Load an xml file into the XML parser and dump the contents • Use 25-2xmlload.php to load 25-1messages.xml as an object • Dump the contents of the object Comp Sci 346

  24. Parsing XML with PHP • Example 2: Load an xml file into the XML parser and display the contents • Load 25-3 books.xml into XML parser 25-4xmlparse.php • Break up the elements • and display the contents • Reference on objects in PHP http://us2.php.net/manual/en/language.oop5.php#op5.intro Comp Sci 346

  25. Parsing XML with PHP • Example 3: Rewrite example 1 to load an xml file into the XML parser and display the contents • Use 25-4xmlload1.php to load 25-1messages.xml as an object • Display the contents of the object • What are the changes? Comp Sci 346

  26. Summary • Conclusions? • Description of data • Method of data exchange • Well structured files Comp Sci 346
