<?xml version=“1.0” encoding=“UTF-8” ?>
<xsl:stylesheet version=“1.0” xmlns:xsl=“http://www.w3.org/1999/XSL/Transform”>
<xsl:template match=“/”>
<html>
<head>
<title>Kenny’s trip to the Zoo</title>
</head>
<body>
<table>
<xsl:for-each select=“ZooTrip/photo”>
<xsl:sort select=“@title” />
<tr>

<table>
<tr>
<td valign=“top”>
<xsl:call-template name=“print_image”>
<xsl:with-param name=“filename” select=“@filename” />
</xsl:call-template>
<br />
<xsl:call-template name=“print_title”>
<xsl:with-param name=“title” select=“@title” />
</xsl:call-template>
<xsl:call-template name=“print_animals”>
<xsl:with-param name=“name” select=“animals/name” />
