在xsl中是可以使用JavaScript等指令碼語言的，但要遵守XML規範。 所以要用 <xsl:comment> <![CDATA[ ]]> </xsl:comment>括起來。
例如以下一個xsl可以實現滾屏效果：
<?xml version="1.0" encoding="utf-8"?>
<html xmlns:xsl="http://www.w3.org/TR/WD-xsl">
<head>
<script language="JavaScript" >
<xsl:comment>
<![CDATA[
var position = 0;
var bswitch = 0;
function scroller() {
// document.getElementById("aa").innerHTML =document.body.clientHeight;
if (bswitch==0 && position <=document.body.scrollHeight-document.body.clientHeight) {
position++;
}else{
bswitch = 1;
}
if (bswitch==1 && position >=0) {
position--;
}else{
bswitch = 0;
}
scroll(0,position);
clearTimeout(timer);
var timer = setTimeout("scroller()",30);
timer;
}
]]>
</xsl:comment>
</script>
</head>
<body bgcolor="#333355" style="color:#33FF66;overflow-x:hidden;overflow-y:hidden">
