XSLT for-each循环和格式化表行

Question

我怎样才能修改下面的xsl,以便在for-each循环中放置图像,每个表行放置2个图像,而不是4个(它当前的作用).

我相信它与mod功能有关吗？

我尝试将foreach兄弟循环拆分到另一行,但只有第一个图像显示在第一行,其余图像显示在第二行.

<xsl:for-each select="Finding">
  <xsl:if test="FindingType = 'A'">
  <xsl:variable name="nImage" select="count(Image)" />
    <tr><td class="di"><table width="100%" class="findings">
  <tr><td class="shade" colspan="4"><p class="g"><b>Finding</b></p></td></tr>
  <xsl:for-each select="Image[position() mod 4 = 1]">
<tr><td width="25%" align="left" valign="top"><p class="g"><img src="{.}" height="128" width="128" hspace="12"/><br />
    <xsl:value-of select="@Type" /><xsl:text> </xsl:text>    <xsl:value-of select="@SubType" />
    <xsl:if test="@Position != ''"> (<xsl:value-of select="@Position" />)         </xsl:if><br /><br />
</p>
    </td></tr>
<tr><xsl:for-each select=". | following-sibling::Image[position() &lt; 4 and (position() mod 4 = 0 or position() mod 4 = 1 or position() mod 4 = 2)]">
    <td width="25%" valign="top" align="left"><p class="g">
    <xsl:if test="(string-length(following-sibling::Image/.) > 0)">
    <img src="{following-sibling::Image/.}" height="128" width="128" hspace="12" />
    </xsl:if>
    <br />
        <xsl:value-of select="following-sibling::Image/@Type" />        <xsl:text> </xsl:text>    
    <xsl:value-of select="following-sibling::Image/@SubType" />
        <xsl:if test="following-sibling::Image/@Position != ''"> (<xsl:value-of select="following-sibling::Image/@Position" />)         </xsl:if>
<br /><br /></p>
</td>
</xsl:for-each>
  <xsl:if test="$nImage = 2">
    <td width="25%" />
  </xsl:if>
</tr>

Answer 1

答案很简单:更换4的2,甚至更好,定义一个全局,参数pNumCols与价值2.

您将进行以下更改:

1. 在全球范围内添加此行:<xsl:param name="pNumCols" select="2"/>

2. 替换:

   <xsl:for-each select="Image[position() mod 4 = 1]">

同

<xsl:for-each select="Image[position() mod $pNumCols = 1]">

0.3.替换:

<xsl:for-each select=". | following-sibling::Image
              [position() &lt; 4 
             and (position() mod 4 = 0 or position() mod 4 = 1 
                 or position() mod 4 = 2)]">

有:

<xsl:for-each select=". | following-sibling::Image
                               [not(position() >= $pNumCols)]">

请注意:

<xsl:for-each select=". | following-sibling::Image
              [position() &lt; 4 
             and (position() mod 4 = 0 or position() mod 4 = 1 
                 or position() mod 4 = 2)]">

相当于更短的:

<xsl:for-each select=". | following-sibling::Image[position() &lt; 4 ]">
