而我的xslt的代码为
<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
<xsl:template match="/">
<xsl:apply-templates select="tree/root/folder"/>
</xsl:template>

<xsl:template match="tree/root/folder">
 <xsl:for-each select=".">
  <h2><xsl:value-of select="@name"/></h2>
  <xsl:for-each select="./folder">
   <h3><xsl:value-of select="@name"/></h3>
   <xsl:for-each select="./folder">
    <h4><xsl:value-of select="@name"/></h4>
    <xsl:for-each select="./folder/leaf">
    <h4>
    <center>
    <a href="{@tooltip}">
    <xsl:value-of select="@name"/>
    </a>
    </center>
    </h4>
    </xsl:for-each>
   </xsl:for-each>
  </xsl:for-each>
 </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

现在我碰到的问题是，无法将链接的内容显示出来，注：我的链接文件是放在同目录下。

还有，<xsl:template match="folder">
