标签： xml xslt

我正在学习XML和XSLT，我有两个部分代码，一个是XML，另一个是XSLT，

这是我的XML文件

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="xslt.xslt"?>

这是我的XSLT代码

<?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>
    <h2>Try to display only 9 or 12</h2>
      <xsl:for-each select="/groups/elements">
       <xsl:sort select="PostDate" order="descending"/>
        <b><xsl:value-of select="PostDate" /></b> - 
        <font color='red'><xsl:value-of select="name" /></font>

        <p></p>
      </xsl:for-each>

  </body>
  </html>
</xsl:template>

</xsl:stylesheet>

我的问题是如何限制商品编号只显示12并使其显示在页面上3个项目或每行4个项目？

我发现有人使用位置，只是不知道要达到限制数字和行的位置？

您可以在此处复制并粘贴我的代码，以查看输出http://markbucayan.appspot.com/xslt/index.html

非常感谢任何建议和解决方案

解决了数字限制问题，添加大于或小于标记， 仍然不知道如何使行只显示3个项目或4行一行

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"

    <xsl:template match="/">

      <html>
      <body>
        <h2>Try to display only 9 or 12</h2>
          <xsl:for-each select="/groups/elements">
            <xsl:sort select="PostDate" order="descending"/>
            <xsl:if test="not(position() > 10)">
            <b><xsl:value-of select="PostDate" /></b> - 
            <font color='red'><xsl:value-of select="name" /></font>
           <p></p>
           </xsl:if>
