XSLT

Sample Gallery

Before we get into more advanced topics, we’ll transform our Hello World document in other ways. We’ll look through simple stylesheets that convert our small XML document into the following things:

• A Scalable Vector Graphics (SVG) File

• A PDF file

• A Java program

• A Virtual Reality Modeling Language (VRML) file

The Hello World SVG File

Our first example will convert our Hello World document into an SVG file:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:output method="xml"
    doctype-public="-//W3C//DTD SVG 20001102//EN"
    doctype-system=
      "http://www.w3.org/TR/2000/CR-SVG-20001102/DTD/svg-20001102.dtd"/>

  <xsl:template match="/">
    <svg width="8cm" height="4cm">
      <g>
        <defs>
          <radialGradient id="MyGradient"
            cx="4cm" cy="2cm" r="3cm" fx="4cm" fy="2cm">
            <stop offset="0%" style="stop-color:red"/>
            <stop offset="50%" style="stop-color:blue"/>
            <stop offset="100%" style="stop-color:red"/>
          </radialGradient>
        </defs>
        <rect style="fill:url(#MyGradient); stroke:black"
          x="1cm" y="1cm" width="6cm" height="2cm"/>
        <text x="4cm" y="2.2cm" text-anchor="middle" 
          style="font-family:Verdana; font-size:24; 
          font-weight:bold; fill:black">
          <xsl:apply-templates select="greeting"/>
        </text>
      </g>
    </svg>
  </xsl:template>

  <xsl:template match="greeting">
    <xsl:value-of select="."/>
  </xsl:template>

</xsl:stylesheet>

As you can see from this stylesheet, most of the code here simply sets up the structure of the SVG document. This is typical of many stylesheets; ...
