以下代码，怎样加首页和尾页：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www. version="1.0">
<xsl:param name="size" select="5"/>
<xsl:template match="list">
<html>
<script>
<![CDATA[
function nextPage(num){
document.getElementById("content"+num).style.display="";
num--;
document.getElementById("content"+num).style.display="none";
}
function prevPage(num){
document.getElementById("content"+num).style.display="";
num++;
document.getElementById("content"+num).style.display="none";
}
function onInitialize(){
var i = 1;
document.getElementById("content"+i).style.display = "";
}
]]>
</script>
<body onload="onInitialize()">
<xsl:apply-templates select="item[position() mod $size = 1]">
<xsl:with-param name="pages" select="ceiling(count(item) div $size)"/>
</xsl:apply-templates>
</body>
</html>
</xsl:template>
