Question

我正在使用此algo

http://www.jenitennison.com/xslt/grouping/muenchian.html用于分组。我可以使用那个算法。但我面临一个问题。我有一个xml我在Over上应用分组。我能够显示我的数据。但有时候@over变成{{ 1}} ..我不想显示那些数据.. 这是我的代码 http://xsltransform.net/pNmBxZY/1

转型

blank

当前结果

我不想遍历具有over::: <h1></h1> <table id=""> <tr> <td>balls:::</td> <td>runs:::0</td> </tr> <tr> <td>balls:::</td> <td>runs:::0</td> </tr> </table> @Over的Node ..请参阅xml中的示例

blank

我不想遍历id =“14”，因为它没有超值。但是当前代码正在这样做，为什么它显示在html部分之上？如何申请支票？

目前最后一个节点显示如此

 <Node Id="14" Over=""

我们能表现得那样吗

over::: 
   <h1>3</h1>
   <table id="">
      <tr>
         <td>balls:::1</td>
         <td>runs:::0</td>
      </tr>
      <tr>
         <td>balls:::2</td>
         <td>runs:::0</td>
      </tr>
      <tr>
         <td>balls:::3</td>
         <td>runs:::1</td>
      </tr>
      <tr>
         <td>balls:::4</td>
         <td>runs:::0</td>
      </tr>
      <tr>
         <td>balls:::5</td>
         <td>runs:::1</td>
      </tr>
   </table>

@ over。@ ball （最后一个节点）

Answer 1

如果我理解正确，你想改变：

<xsl:apply-templates select="Node[generate-id() = generate-id(key('node-by-over', @Over)[1])]"/>

为：

<xsl:apply-templates select="Node[@Over>0][generate-id() = generate-id(key('node-by-over', @Over)[1])]"/>

如何在xslt中删除空值？
