我在下面的输入XML中选择我想要的内容时遇到了一点麻烦。我需要按keys/key进行选择，这里有多个<key>子节点。

我想要的特定<portfolioSummary>节点基于<key>属性:
1)第一个XSLT模板:1a)其中属性类型="交易对手"，值="DummyCounterpartyIRS"andb) where attribute type="ExpType" AND value="InternalVaR_IRS_LCH"
2)第二个XSLT模板:2a)其中属性类型="交易对手"值="DummyCounterpartyCDS"ANDb) where attributes type="ExpType" AND value="InternalVaR_CDS_LCH"
它应该最终拉两个<portfolioSummary>节点为两个portfolioId="36"和portfolioId="72"
这是我有的，但它没有正确选择:

第一个模板中的<xsl:apply-templates>没有选择任何东西。您正在匹配/*并选择以不存在的元素开头的绝对位置路径:razorOutbound .
改为:
<xsl:template match="/">
<collection>
<xsl:apply-templates select="Outbound/body/portfolioSummary[descendant::portfolio/keys/key[@type='Counterparty' and @value='DummyCounterpartyIRS']]"/>
<xsl:apply-templates select="Outbound/body/portfolioSummary[descendant::portfolio/keys/key[@type='Counterparty' and @value='DummyCounterpartyCDS']]"/>
</collection>
</xsl:template>
对于选择，选择了四个组合，而不是两个。第一个表达式:
//body/portfolioSummary[portfolio/keys/key[@type='Counterparty' and @value='DummyCounterpartyIRS']]
将匹配两个组合(36和37)，另一个将匹配71和72。*模板将为每一对调用两次，并且总是匹配一个或另一个xsl:when。如果您只想选择其中的一个，则必须添加一些其他限制。
