在网络上经常可以看到背景色按行交替设置的表格，比较美观。但未必需要什么高深的服务器技术，用简单的xsl+xml照样能很好的实现他们。
比如，我们有这么一个记录网址的xml文档：
<?xml version="1.0" encoding="utf-8" ?>
<?xml-stylesheet type="text/xsl" href="XSLTFileLlink.xsl" ?>
<items>
<roomitem>
<text>新浪</text>
<link>http://www.sina.com.cn</link>
</roomitem>
<roomitem>
<text>yahoo</text>
<link>http://www.yahoo.com</link>
</roomitem>
<roomitem>
<text>google</text>
<link>http://www.google.com</link>
</roomitem>

现在，我希望按照其分类，把他表现成两个颜色按行交替的表格。如下图所示：
Xsl可以如此写出，
<?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>
<body>
<!--
This is an XSLT template file. Fill in this area with the
XSL elements which will transform your XML to XHTML.
