带有mod的XSL表输出

Question

I'm trying to output a table using XSL from a list of articles in the following format. The needs to be repeated, so full, split, split, full, split, split, etc.

<table>
    <tr>
        <td>Full</td>
    </tr>
    <tr>
        <td>Split</td>
        <td>Split</td>
    </tr>
    ... 
</table>

So the 1st and every forth article is a full article, but the rest are split articles and that row would contain 2x td's, not just one.

If I was doing this is PHP or similar I'd conditionally add the opening and closing tr's as required. It seems I can't do that in XSL. So I don't think I can use xsl:if on the tr's.

<xsl:choose>
<xsl:when test="position() mod 4 = 0 or position() = 1">
    <tr>
        <td>Full</td>
    </tr>        
</xsl:when>
<xsl:otherwise>
    <tr>
        <td>Split</td>
    </tr>
</xsl:otherwise>
</xsl:choose>

Can anyone point me in the right direction?

Many thanks

Answer 1

Did you try your own code? There's no reason you can't wrap tags in XSL conditions, as you have. Here's what I presume to be your intended result:
