有两个树节点与节点不同。当我循环并使用代码时，我在同一行中获得两个值。尝试用节点过滤它但无法过滤。任何人都可以提供指针吗？问题是第三行。

Answer 1

查看您的数据。例如。对于2016年，您有两个 bmCalDet 节点。一个 val = 11.96，另一个 val = -21.68。

这两个在您致电时都会返回这些节点 2016年key('bmCalDet-by-year',...)。

因此，当您创建第3行时，您需要仅这些值的第一个。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" />

注意添加[1]以仅获取key返回的第一个节点。

要获取第二组值（在第4行中），请重复整个片段创建第3行。但是这一次，在for-each循环中，你需要只有第二个元素 key(...)返回的内容。因此，而不是[1]（在key(...)之后）写[2]。

Answer 2

您似乎需要在xsl:for-each上使用bmCalYearDet，然后在密钥上添加条件以过滤benchMarkOrder

<!-- 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>

当您使用XSLT 2.0时，您也可以像这样编写

<!-- 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>

xsl：key filter选项，用于显示不同行中的数据值
