Xslt XSL：通过检查变量打印分隔符

我是XSL新手，我想做一些类似的事情

var oldvalue= '' 
for each
   get currentvalue
   if (oldvalue != currentvalue)
   {
         print divider
         oldvalue = currentvalue
    }      
end for  

我已经试过了

<xsl:variable name="oldname" select="name" /> 

<xsl:for-each select="myxpathstring">
  <xsl:choose>
      <xsl:when test="$newname = $newname">
        <xsl:variable name="oldname" select="$newname" />
        <div class='divider'>divider stuff </div>
       </xsl:when>

      <xsl:otherwise>No</xsl:otherwise>
 </xsl:choose>

</xsl:for-each>

分隔器材料
不

但这不起作用，因为我无法更新'oldname'变量。 有人有办法吗

完整的XSL（带有JSP参数，因为我是动态生成XSL的）

创建一个返回新值的函数，将旧值和myxpathstring中的值列表作为参数。

如果我理解您的XSLT正确，您必须使用它。有关此方法工作原理的说明，请阅读

XML:

结果:

您必须在这里使用不同的方法。你能提供一个输入XML的小例子吗？我已经检查了你的例子，它是有效的，但我没有把它翻译成mine@user1194465：在问题中提供输入XML和结果XML。
