我想给第一场比赛编号1，给第二场比赛编号2，但问题是，在每次比赛之后，它同时给出1和2。如何才能使每个匹配只使用一个数字。

谢谢。

输出：

<table border="1">
<tbody><tr bgcolor="#9acd32">
<th>Title</th>
<th>Artist</th>
</tr>
<tr>
<td>Empire Burlesque</td>
<td>Bob Dylan</td>
<td>1985</td>
<td>
1
2
</td>
</tr>
<tr>
<td>Hide your heart</td>
<td>Bonnie Tyler</td>
<td>1988</td>
</tr>
<tr>
<td>Greatest Hits</td>
<td>Dolly Parton</td>
<td>1985</td>
<td>
1
2
</td>
</tr>
</tbody></table>

Answer 1

我想这就是你想要的-假设你希望Bob Dylan有第一个notold/list (即'1')，Bonnie Tyler没有数字，Dolly Parton有第二个notold/list。

它的工作方式是在匹配相同过滤器的所有cd的列表中找到当前匹配的cd的位置，计算匹配列表中的preceding-sibling，然后基于基于1的索引访问适当的notold/list项。
