Question

我在以下输入XML中准确选择了我想要的内容时遇到了一些麻烦。我需要基本上选择keys/key，其中有多个<key>子节点。

例如，这是一个示例输入XML文件：

  <Outbound environment="" request="selectPortfolios">
<body matchedRecordCount="4">       
    <portfolioSummary portfolioId="36">
        <portfolio id="36">
            <currency>USD</currency>
            <keys>
                <key displayValue="DummyCounterpartyIRS" sequenceNumber="100" sequenceValue="DummyCounterpartyIRS" type="Counterparty" value="DummyCounterpartyIRS"/>
                <key displayValue="Internal VaR IRS LCH" sequenceNumber="2000" sequenceValue="80" type="ExpType" value="InternalVaR_IRS_LCH"/>
            </keys>
            <status>Unapproved</status>
        </portfolio>
        <exposureProfile>
            <node date="2014-05-06">
                <tag>HSVaR 5D 100 ES</tag>
                <exposure>492692</exposure>
            </node>
        </exposureProfile>
    </portfolioSummary>
    <portfolioSummary portfolioId="37">     
        <portfolio id="37">
            <currency>USD</currency>
            <keys>
                <key displayValue="DummyCounterpartyIRS" sequenceNumber="100" sequenceValue="DummyCounterpartyIRS" type="Counterparty" value="DummyCounterpartyIRS"/>
                <key displayValue="Internal VaR CDS LCH" sequenceNumber="2000" sequenceValue="81" type="ExpType" value="InternalVaR_CDS_LCH"/>
            </keys>
            <status>Unapproved</status>
        </portfolio>
        <exposureProfile>
            <node date="2014-05-09">
                <tag>Node Scenario 4</tag>
                <exposure>248057</exposure>
            </node>
            <node date="2014-05-10">
                <tag>Node Scenario 5</tag>
                <exposure>373130</exposure>
            </node>
            <node date="2014-05-11">
                <tag>EXPECTED_SHORTFALL 99.7</tag>
                <exposure>373130</exposure>
            </node>
        </exposureProfile>
    </portfolioSummary>
    <portfolioSummary portfolioId="71">
        <readOnly>false</readOnly>
        <portfolio id="71">
            <currency>USD</currency>
            <keys>
                <key displayValue="DummyCounterpartyCDS" sequenceNumber="100" sequenceValue="DummyCounterpartyCDS" type="Counterparty" value="DummyCounterpartyCDS"/>
                <key displayValue="Internal VaR IRS LCH" sequenceNumber="2000" sequenceValue="80" type="ExpType" value="InternalVaR_IRS_LCH"/>
            </keys>         
            <status>Unapproved</status>
        </portfolio>
        <exposureProfile>
            <node date="2014-05-06">
                <tag>HSVaR 5D 100 ES</tag>
                <exposure>58</exposure>
            </node>
        </exposureProfile>
    </portfolioSummary>
    <portfolioSummary portfolioId="72">
        <readOnly>false</readOnly>
        <portfolio id="72">
            <currency>USD</currency>
            <keys>
                <key displayValue="DummyCounterpartyCDS" sequenceNumber="100" sequenceValue="DummyCounterpartyCDS" type="Counterparty" value="DummyCounterpartyCDS"/>
                <key displayValue="Internal VaR CDS LCH" sequenceNumber="2000" sequenceValue="81" type="ExpType" value="InternalVaR_CDS_LCH"/>
            </keys>
            <status>Unapproved</status>
        </portfolio>
        <exposureProfile>
            <node date="2014-05-09">
                <tag>Node Scenario 4</tag>
                <exposure>9</exposure>
            </node>
            <node date="2014-05-10">
                <tag>Node Scenario 5</tag>
                <exposure>12</exposure>
            </node>
            <node date="2014-05-11">
                <tag>EXPECTED_SHORTFALL 99.7</tag>
                <exposure>12</exposure>
            </node>
        </exposureProfile>
    </portfolioSummary>
</body>
</Outbound>

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=＆＃34;交易对手＆＃34;和价值=＆＃34; DummyCounterpartyIRS＆＃34;和 1b）其中属性类型=＆＃34; ExpType＆＃34; AND value =＆＃34; InternalVaR_IRS_LCH＆＃34;

2）第二个XSLT模板： 2a）其中属性类型=＆＃34;交易对手＆＃34;值=＆＃34; DummyCounterpartyCDS＆＃34;和 2b）其中属性类型=＆＃34; ExpType＆＃34; AND value =＆＃34; InternalVaR_CDS_LCH＆＃34;

最终应该为portfolioId =＆＃34; 36＆＃34;提取两个<portfolioSummary>个节点。和portfolioId =＆＃34; 72＆＃34;

这是我拥有的，但它没有正确选择：

Answer 1

第一个模板中的<xsl:apply-templates>未选择任何内容。您正在匹配/*并选择绝对位置路径，该路径以不存在的元素开头：razorOutbound。

将其更改为：

<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，选择四个投资组合，而不是两个。第一个表达：

//body/portfolioSummary[portfolio/keys/key[@type='Counterparty' and @value='DummyCounterpartyIRS']]

将匹配两个投资组合（36和37），另一个将匹配71和72. *模板将为每对调用两次，并且始终匹配一个或其他xsl:when。如果您只想选择其中一个，则必须为其添加一些其他限制。

使用XSLT选择多个子节点
