有两个不同于节点的树节点。当我在同一行中得到两个值时，循环并使用代码。尝试使用节点对其进行筛选，但无法进行筛选。谁能给我指点一下吗？问题在于第三行。查看您的数据。例如，2016年，您有两个bmCalDet 节点。一个val=11.96，另一个val=-21.68 调用时将返回这两个节点 2016年的关键（'bmCalDet-by-year'，…） 因此，当您创建第3行时，只需要这些值中的第一个。 然后将循环内的指令更改为：
<xsl:value-of select="key('bmCalDet-by-year', substring-before(rtnDate, '-'),
$catalog)[1]/val" />
[1]键返回的第一个节点
要获得第二组值（第4行），请重复整个片段
正在创建第3行。
但是，这一次，对于每个内部，您只需要来自
键（…）
返回的内容。
因此，与其写[1]
（在键（…）
之后），不如写[2]
，看起来您需要在bmCalYearDet
上为每个添加一个xsl:
<!-- 3rd row here is the issue with the code-->
<xsl:for-each select="performanceVO/bmCalYearDet">
<xsl:variable name="benchMarkOrder" select="benchMarkOrder" />
<tr>
<th>val</th>
<xsl:for-each select="$years/fAnReVal">
<td>
<xsl:value-of select="key('bmCalDet-by-year', substring-before(rtnDate, '-'), $catalog)[../benchMarkOrder = $benchMarkOrder]/val" />
</td>
</xsl:for-each>
</tr>
</xsl:for-each>

在使用XSLT2.0时，也可以这样编写
<!-- 3rd row here is the issue with the code-->
<xsl:for-each select="performanceVO/bmCalYearDet">
<xsl:variable name="benchMarkOrder" select="." />
<tr>
<th>val</th>
<xsl:for-each select="$years/fAnReVal">
<td>
<xsl:value-of select="key('bmCalDet-by-year', substring-before(rtnDate, '-'), $benchMarkOrder)/val" />
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
