Example

Unparsed entities are rarely used; they typically refer to non-XML data, as in the entity author-picture in this XML document:

<?xml version="1.0"?>
<!-- unparsed-entity.xml -->
<!DOCTYPE book [
  <!ENTITY author-picture PUBLIC "-//OReilly//Author Images//DT"
    "dougtidwell.jpg" NDATA JPEG>
]>

<book>
  <prolog cover-image="author-picture"/>
  <body>
    <p>Pretend that lots of useful content appears here.</p>
  </body>
</book>

We’ll use this stylesheet to get the public URI of our unparsed entity:

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

  <xsl:output method="text"/>

  <xsl:template match="/">
    <xsl:text>&#xA;A test of the unparsed-entity-</xsl:text>
    <xsl:text>uri() function:</xsl:text>

    <xsl:text>&#xA;&#xA;   </xsl:text>
    <xsl:text>The URI of the cover image is:&#xA;      </xsl:text>
    <xsl:value-of 
      select="unparsed-entity-uri(/book/prolog/@cover-image)"/>
    <xsl:text>.&#xA;</xsl:text>
  </xsl:template>

</xsl:stylesheet>
