我正在开发Umbraco的自定义博客. Umbraco将XML作为输出吐出,然后使用XSLT读取.

XML的结构如下

>博客

>博客中心

>房间

>博客文章
>博客文章
>博客文章

>房间

>博客文章

>博客中心

>房间

>博客文章

这是XML代码,我已经清理了很多,以使其至少具有一定的可读性.

在Umbraco XSLT样式表中,有一个参数可以传递给当前页面.

<xsl:param name="currentPage" />

这将始终是父节点< Blog />,因此我们必须在此处启动表单.

您会注意到< Blog />之间存在中间节点.和< BlogPost />但我们想要计算每个< BlogCentre />中的BlogPosts总数.和< Room />.

为此,我一直在使用

<xsl:for-each select="$currentPage/descendant::BlogPost" />

选择所有博客帖子,无论中心/房间.

现在我的要求是按月和年份对每个博客帖子进行分组(包括每个月的帖子计数).我想要将它们分组的日期是属性createDate,除非有一个名为< archiveUnder> some-date-here< / archiveUnder>的子节点.进一步解释

更新
我可以通过检查属性是否为空来轻松完成此部分,因此如果需要,解决方案可以省略此部分.

<BlogPost createDate="2010-10-08T17:52:22">
    <!-- no archiveUnder -->
</BlogPost>

^使用创建日期

<BlogPost createDate="2010-10-08T17:52:22">
    <archiveUnder>2010-10-08T17:51:19</archiveUnder>
</BlogPost>

^使用archiveUnder

Finally, here’s an example of the expected output.

<ul>
    <li>
        <h3>2010</h3>
        <ul>
            <li>September (4)</li>
            <li>August (2)</li>
            <li>June (5)</li> <!-- No July because there are no posts -->
        </ul>
    </li>
    <li>
        <h3>2009</h3>
        <ul>
            <li>April (4)</li>
            <li>March (2)</li>
            <li>January (5)</li> <!-- No February because there are no posts -->
        </ul>
    </li>
</ul>

产生想要的,正确的结果：

<ul>
   <li>
      <h3>2010</h3>
      <ul>
         <li>October (7)</li>
         <li>September (2)</li>
         <li>August (3)</li>
         <li>July (1)</li>
         <li>June (3)</li>
         <li>May (1)</li>
         <li>April (1)</li>
         <li>March (1)</li>
         <li>February (1)</li>
         <li>January (1)</li>
      </ul>
   </li>
   <li>
      <h3>2009</h3>
      <ul>
         <li>December (1)</li>
         <li>November (1)</li>
         <li>October (1)</li>
      </ul>
   </li>
</ul>

请注意：

使用> Muenchian Grouping – 用于确定不同年份和确定每年的不同月份.
>使用表达式在createDate属性和archiveUnder子项之间选择日期：

concat(archiveUnder,@ createDate [not(archiveUnder)])

如果archiveUnder缺失或为空,则此并置仅选择@createDate.

0.3.即使元素的日期未排序,转换也会产生正确的结果.
