  4. What is XSLT? • A way to transform XML • To HTML • To text • Not too good at other formats ( • A way to add formatting • A programming language • Not for end users • Not too hard for easy things • Will need to use “real” programming where it fails INFO 440: Information System Design * Fall 2004 * Bob Boiko * MSIM Associate Chair

  5. Why use It? • Standardizes your publications • Reuse • Create one transform (i.e., XSL file) many pages • One content chunk many presentations • Assures well formed output • Separates processing code from presentation code (sort of) INFO 440: Information System Design * Fall 2004 * Bob Boiko * MSIM Associate Chair

  6. Major Player XML • XSL is XML! • All the same rules apply <xsl:stylesheet> <xsl:templatematch="/">      <h1>           <xsl:value-ofselect="//title"/>      </h1>      <h2>           <xsl:value-ofselect="//author"/>      </h2> </xsl:template></xsl:stylesheet> INFO 440: Information System Design * Fall 2004 * Bob Boiko * MSIM Associate Chair

  7. Major Player Templates & XPath • The whole file is a stylesheet • Stylesheets have templates • Templates have selectors • Selectors use XPath • Templates contain value-of’s • Value-of’s contain selectors INFO 440: Information System Design * Fall 2004 * Bob Boiko * MSIM Associate Chair
