12 4/17/2015Comp Sci 34612 How to render an XML Document?  Extensible Stylesheet Language (XSL)  Specify how programs should render XML document data XSL-FO (XSL Formatted Objects) XSL-FO (XSL Formatted Objects) Vocabulary for specifying formattingVocabulary for specifying formatting XSLT (XSL Transformation) XSLT (XSL Transformation) Defines rules for transforming one XML documment to anotherDefines rules for transforming one XML documment to another From Source tree to Result treeFrom Source tree to Result tree Xpath Xpath Locate parts of the source tree document that match templates defined in the XSL stylesheetLocate parts of the source tree document that match templates defined in the XSL stylesheet

13 4/17/2015Comp Sci 34613 Cricket Popular in Commonwealth nations. Processing Instruction (PI) references the XSL stylesheet games.xsl Specifies location of XSLT delimits a PI target

14 4/17/2015Comp Sci 34614 Baseball Popular in America. Soccer (Football) Popular sport in the world. Games.xml continued

15 4/17/2015Comp Sci 34615 XSL style sheet <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"/> Start style sheet Binds namespace xsl to W3C XSLT URI Output as xhtml file. Doctype as xhtml “/” is used to select the root

17 4/17/2015Comp Sci 34617 Rendering games.xml

18 4/17/2015Comp Sci 34618 Using XSLT to Sort and Format Data Compare the source in sorting.xml (chapters are out of order) and the rendering

20 4/17/2015Comp Sci 34620 Other applications using XML  DOM  PHP

21 4/17/2015Comp Sci 34621 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

22 4/17/2015Comp Sci 34622 Use XML with PHP  XML functionality is based on libxml2 library Enabled by default on Windows and Linux/Unix Enabled by default on Windows and Linux/Unix  Check for the following with phpinfo() dom dom libxml libxml simplexml simplexml

23 4/17/2015Comp Sci 34623 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 Use 25-2xmlload.php to load 25- 1messages.xml as an object Dump the contents of the object Dump the contents of the object

24 4/17/2015Comp Sci 34624 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 Load 25-3 books.xml into XML parser 25- 4xmlparse.php Break up the elements Break up the elements and display the contents and display the contents  Reference on objects in PHP http://us2.php.net/manual/en/language.oop5.php#op5.intro

25 4/17/2015Comp Sci 34625 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 Use 25-4xmlload1.php to load 25- 1messages.xml as an object Display the contents of the object Display the contents of the object  What are the changes?
