我有一个XML和XSLT文件，我希望XSLT自动从同一XML文件中的另一个节点获取值。
XSLT第68行我知道不应该这样放，但我真的不知道如何将值传递给键('Description2-by-id'，由于

实际结果
|ID |Date |Country |Description1 |Description2 |Description3 |Reference |ReferenceName |ReferenceDescription2code |ReferenceDescription2|
|752 |15-Oct-2013 |[BB] Antarctica [True] |P1 |P22 |P211 |9811 |National List |1 | |
|752 |15-Oct-2013 |[BB] Antarctica [True] |P2 | | |9811 |National List |1 | |
|758 |15-Oct-2013 |[BC] Abkhazia [False] |E1 |E11 |E111 | | | | |
|758 |15-Oct-2013 |[BC] Abkhazia [False] | | | | | | | |
我期望的结果是
|ID |Date |Country |Description1 |Description2 |Description3 |Reference |ReferenceName |ReferenceDescription2code |ReferenceDescription2|
|752 |15-Oct-2013 |[BB] Antarctica [True] |P1 |P22 |P211 |9811 |National List |1 |P21 |
|752 |15-Oct-2013 |[BB] Antarctica [True] |P2 | | |9811 |National List |1 |P21 |
|758 |15-Oct-2013 |[BC] Abkhazia [False] |E1 |E11 |E111 | | | | |
|758 |15-Oct-2013 |[BC] Abkhazia [False] | | | | | | | |
又来了?
我担心这个例子不够清楚(有太多相似的值)，并且没有解释逻辑(!)，所以这只不过是一个猜测:
<td>
<xsl:value-of select="key('Description2-by-id', key('Reference-by-code', $varReference)/@Description2Id)"/>
</td>
这所做的是(1)从匹配的ReferenceName中获得@Description2Id值，(2)使用它通过'Description2-by-id'键获得Description2Name值。
