标签： xml xslt

我想我只是打开一个新问题，也可以帮助那些寻求解决方案的人。我想从每个第3项添加一个类。

这是我的xml代码

这是我的XSLT 

<?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"/>
            <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>
          </xsl:for-each>

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

    </xsl:stylesheet>

只想要一个简单的方法来插入课程，非常感谢

我想要

        <div clas="item">

        2012-07-04 - //3 

        2012-05-28 - //9 

       <div class="third"> 2012-05-14 - //8 </div>

        2012-03-04 - //1 

        2012-01-04 - //7

此转化：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

    <xsl:template match="/">
      <div class="item">
          <xsl:for-each select="/groups/elements">
            <xsl:sort select="PostDate" order="descending"/>
            <xsl:if test="not(position() > 10)">
                <xsl:choose>
                  <xsl:when test="position() mod 3 = 0">
                  <xsl:text>&#xA;</xsl:text>
                    <div class="third">
                      <xsl:apply-templates select="."/>
                    </div>
                  </xsl:when>
                  <xsl:otherwise>

会产生想要的正确结果： 

<div class="item">
2012-07-04 - //3
2012-05-28 - //9
<div class="third">2012-05-14 - //8</div>
2012-03-04 - //1
2012-01-04 - //7
<div class="third">2011-12-20 - //11</div>
2011-11-07 - //12
2011-07-09 - //13
<div class="third">2011-03-04 - //2</div>
2011-02-25 - //10</div>

答案 1 :(得分：0)

我有一段时间没有做过xsl所以我的XSL有点生疏了。

然而，这应该有效，其中三个对应于每个x重复的数量

 <xsl:when test="position() mod 3 = 0">
     <!-- your xml render here-->
 </xsl:when>
 <xsl:otherwise><!-- your other xml here --> </xsl:otherwise>

mod运算符也适用于其他场景
