  2. What is XSL • Extensible Style sheet Language • An XML-based language used to create to style sheets

  3. What it does • Define layout of the output document • Define font and alignment of text • Define where to get the data from within the input document • Rearrange elements • Source tree( input document ) • Result tree( output document )

  4. Composition of XSL • A transformation language • which is named XSLT • switch a tag to another tag • EX. XSL -> HTML, XML -> HTML + CSS • Rearrange element and add contents • A language used to describe XML document for display • XSL Formatting Objects • More powerful display

  5. CSS and XSL • Impose a standard style on a whole document • but, there are several differences.

  6. CSS Only define property XSL change order of elements for display iterative and selective process to elements add contents Differences:CSS and XSL

  7. CSS Selector and Properties selector { properties } XSL Pattern and Formatting object <xsl:template pattern="pattern"> <formatting objects/></xsl:template> Differences:CSS and XSL • example • quote { display: block; font-size: 90%; margin-left: 0.5in; margin-left: 0.5in } • example • <xsl:template pattern="quote"> <fo:block font-size="90%" indent-start="0.5in" indent-end="0.5in"> <xsl:process-children/> </fo:block></xsl:template>

  8. How do XSLT style sheets works? • XSLT style sheets are built on structures called templates • A template specifies what to look for in the source tree, and what to put into the result tree. • XSLT is written in XML • There are special XSLT elements and attributes

  9. namespace Printing form • <?xml version="1.0" encoding="euc-kr" ?> • <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> • <xsl:output method="html" version="4.0" encoding="euc-kr" /> • <xsl:decimal-format NaN=“none" /> • <xsl:template match="/"> • <html> • <head> • <title><xsl:text>Book list</xsl:text></title> • <link rel="stylesheet" type="text/css" href="books.css" /> • </head> • <h1><xsl:text>Book table</xsl:text></h1> • <table border="1"> • <tr> • <th>No.</th> • <th>ISBN code</th> • <th>Name</th> • <th>Company</th> • <th>Price</th> • <th>date</th> • </tr> • <xsl:apply-templates select="books" /> • </table> • </html> • </xsl:template> css Call <xsl:template match=“books”>~</xsl:templete>
