xsl position()函数 lt and gt 有关问题

xsl position()函数 lt and gt 问题
我的sitemap.xml如下： 
<node> <title>Home </title> <link> <a href="/CMS400Developer/default.aspx" alt="Medical Home">Home </a> </link> <description>Medical Home </description> <node> <title>About Us </title> <link> <a href="/CMS400Developer/aboutus.aspx" alt="About Medical">About Us </a> </link> <description>About Medical </description> <node> <title>Staff </title> <link> <a href="/CMS400Developer/staff.aspx" alt="Staff list">Staff </a> </link> <description>Staff list </description> </node> <node> <title>News </title> <link> <a href="/CMS400Developer/news.aspx" alt="News">News </a> </link> <description>News </description> </node> <node> <title>Careers </title> <link> <a href="/CMS400Developer/jobs.aspx" alt="Careers at Medical Center">Careers </a> </link> <description>Careers at Medical Center </description> </node> <node> <title>Calender </title> <link> <a href="/CMS400Developer/events.aspx" alt="">Calender </a> </link> <description> </description> </node> </node> <node> <title>Services </title> <link> <a href="/CMS400Developer/services.aspx" alt="Services">Services </a> </link> <description>Services </description> </node> <node> <title>Products </title> <link> <a href="" alt="Product page">Products </a> </link> <description>Product page </description> </node> </node> 


现在的xsl文件如下。如果写成]<xsl:if test="position() &lt; $folderCount+2">,可以打印出子目录，没有任何问题。只是当我将lt 改成 gt 后，就只能打出主目录，其对应的子目录就输出不了了。不知道这是什么原因造成的，请各位帮忙！多谢！

[解决办法]
position() &gt; $folderCount+2 的话没有符合的节点，
以上XML中 $folderCount = 2
而position()的值为1,2,3， 都不符合 position() > $folderCount+2
