在xsl fo中处理动态列换行

Question

如何使用xsl fo创建动态列数的表格。列数随每个输入文件而有所不同，但对于单个输入文件而言是固定的。

这里是一个示例XML

<root> 
<ColNo>3</ColNo> 
<Objects> 
<object id="1"> 
<prop1 old="5" new="7"> 
<prop2 old="2" new="1"> 
<prop3 old="3" new="6"> 
</object> 
</Objects> 
</root> 

我想要一个表像下面

Obj1 
------------------------------------------ 
prop1  | prop2   | prop3 
------------------------------------------- 
old | new | old | new  | old | new 
------------------------------------------- 
5 | 7 | 2 | 1  | 3 | 6 

我碰到到number-columns-repeated性质。但无法了解如何使用它..

如果还有更好的方法，请让我来。

谢谢。

你没有指出你已经尝试了多少，但我怀疑没有太多，因为输入数据没有很好地形成。而且你也没有指出如何表示多行数据，所以我在下面通过修改数据添加了额外的信息进行了猜测。

下面是一个完整的解决方案。它使用了两种可用的行填充技术，并且类似于我在教室中使用的插图（以及练习），使用它们。

当我通过一个符合XSL-FO处理器运行下面的输出时，我得到了表格中所列出的问题。

t:\ftemp>type table.xml 
<root> 
<ColNo>3</ColNo> 
<Objects> 
<object id="1"> 
<prop1 old="5" new="7"/> 
<prop2 old="2" new="1"/> 
<prop3 old="3" new="6"/> 
<prop1 old="15" new="17"/> 
<prop2 old="12" new="11"/> 
<prop3 old="13" new="16"/> 
</object> 
</Objects> 
</root> 

t:\ftemp>call xslt table.xml table.xsl table.fo
