使用XSLT将一种xml格式转换为另一种格式

标签： xml xslt xslt-2.0

我有以下xml输入文件，并希望将其转换为不同的xml架构格式。 到目前为止，我所拥有的是工作并生成格式良好的xml输出。

两个挑战：

  1. 我想在我使用多个<xsl:apply-templates/>命令的地方更好地构建我的XSLT。
  2. 我还要处理多个<tradeType>个节点（例如<tradeType>IRS</tradeType>，以及<tradeType>CDS</tradeType>），并且需要我的输出稍有不同<tradeType>值。

    3. 这是<tradeType>IRS</tradeType>的输入样本：

    <collection>
    <Trades_Output>
        <tradeId>IRS-002</tradeId>
        <tradeDate>2007-09-05</tradeDate>
        <tradeType>IRS</tradeType>
        <buySell>BUY</buySell>
        <counterparty>COUNTERPARTY IRS</counterparty>
        <internalUnit>My Company Inc</internalUnit>
        <legOnePayerPartyReference>COUNTERPARTY IRS</legOnePayerPartyReference>
        <legOneReceiverPartyReference>My Company Inc</legOneReceiverPartyReference>
        <legOneStartDate>2007-09-05</legOneStartDate>
        <legOneEndDate>2014-09-05</legOneEndDate>
        <legOneNotional>151521500</legOneNotional>
        <legOneCurrency>GBP</legOneCurrency>
        <legOneRateIndex>LIBOR</legOneRateIndex>
        <legOneSpread>0.0022</legOneSpread>
        <legOneFixedRate></legOneFixedRate>
        <legTwoPayerPartyReference>My Company Inc</legTwoPayerPartyReference>
        <legTwoReceiverPartyReference>COUNTERPARTY IRS</legTwoReceiverPartyReference>
        <legTwoStartDate>2007-09-05</legTwoStartDate>
        <legTwoEndDate>2014-09-05</legTwoEndDate>
        <legTwoNotional>151521500</legTwoNotional>  
        <legTwoCurrency>GBP</legTwoCurrency>
        <legTwoRateIndex></legTwoRateIndex>
        <legTwoSpread></legTwoSpread>
        <legTwoFixedRate>0.04575</legTwoFixedRate>
        <legTwoRateType>FIXED</legTwoRateType>
    </Trades_Output>
    <Trades_Output>
       <tradeId>CDS-002</tradeId>
       <tradeDate>2010-09-27</tradeDate>
       <tradeType>CDS</tradeType>
       <counterparty>COUNTERPARTY CDS</counterparty>
        <internalUnit>My Company Limited</internalUnit>
       <buySell>BUY</buySell>
       <status>OPEN</status>
       <startDate>2007-09-05</startDate>
       <endDate>2014-09-05</endDate>
       <sellerPartyReference>COUNTERPARTY IRS</sellerPartyReference>
       <buyerPartyReference>My Company Inc</buyerPartyReference>
       <instrumentId>RBS (REG) 01/08/2013</instrumentId>
       <currency>GBP</currency>
       <amount>75000000</amount>
       <fixedRate>0.0098</fixedRate>
       <dayCountFraction>ACT/360</dayCountFraction>
     </Trades_Output>
</collection>

    我想要的输出：

     <deal>
 <dealHeader>
      <dealId>IRS-RRT-002</dealId>
      <dealType>IRS</dealType>

    是否有任何其他建议可以提供更好的结构我的XSLT？换句话说，与<xsl:template match="Trades_Output">

    中的所有xml输出相反 谢谢你。 鲍勃

1。我想在我使用多个命令的地方更好地构建我的XSLT。

源XML的设计非常糟糕，如果元素如下所示会更好：

<PayerPartyReference leg="one"/>

由于所有LegOne / LegTwo元素看起来基本相同，但是你使用XSLT 2.0以便使用正则表达式来解决这个问题，我会做这样的事情：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0">
<xsl:output indent="yes"/>

<xsl:template match="/*">
    <body>
        <insertions>
            <xsl:apply-templates select="Trades_Output"/>
        </insertions>
    </body>
</xsl:template>

<xsl:template match="Trades_Output">
    <trade>
        <tradeHeader>
            <xsl:copy-of select="tradeId | tradeDate"/>
        </tradeHeader>
        <product>
            <swap>
                <!-- this will generate two groups for the elements starting with legOne/legTwo -->
                <xsl:for-each-group select="*[matches(name(),'(legOne|legTwo)')]"
                    group-by="substring(name(),1,6)">
                    <swapStream>
                        <!-- 
                          this will apply to legOnePayerPartyReference and legOneReceiverPartyReference
                          when in group legOne and respectively when in group legTwo 
                        -->
                        <xsl:apply-templates select="current-group()[ends-with(name(),'PartyReference')]"/>
                        <calculationPeriodDates>
                            <xsl:apply-templates select="current-group()[ends-with(name(),'Date')]"/>
                        </calculationPeriodDates>
                    </swapStream>
                </xsl:for-each-group>
            </swap>
        </product>
    </trade>
</xsl:template>

<xsl:template match="*[matches(name(),'(legOne|legTwo)PayerPartyReference')]">
    <payerPartyReference href="{.}"/>
</xsl:template>

<xsl:template match="*[matches(name(),'(legOne|legTwo)ReceiverPartyReference')]">
    <receiverPartyReference href="{.}"/>
</xsl:template>

<xsl:template match="*[matches(name(),'(legOne|legTwo)StartDate')]">
    <effectiveDate>
        <unadjustedDate>
            <xsl:value-of select="."/>
        </unadjustedDate>
        <dateAdjustments>
            <businessDayConvention>MODFOLLOWING</businessDayConvention>
        </dateAdjustments>
    </effectiveDate>
</xsl:template>

<xsl:template match="*[matches(name(),'(legOne|legTwo)EndDate')]">
    <terminationDate>
        <unadjustedDate>
            <xsl:value-of select="."/>
        </unadjustedDate>
        <dateAdjustments>
            <businessDayConvention>MODFOLLOWING</businessDayConvention>
        </dateAdjustments>
    </terminationDate>
</xsl:template>
</xsl:stylesheet>

我不清楚你所希望的输出中的大部分内容来自，我猜测很多东西是固定的...但是这应该让你开始。

我还要处理多个<tradeType>个节点（即<tradeType>IRS</tradeType>，以及<tradeType>CDS</tradeType>），并且需要我的输出略有不同基于<tradeType>值。

这完全取决于你的意思略所以也许在这里提供一些关于每个tradeType会有什么不同的信息...最简单的解决方案是每个tradeType只有一个模板< / p> 

<xsl:template match="Trades_Output[tradeType='IRS']">

分别

<xsl:template match="Trades_Output[tradeType='CDS']">

然后在那里有不同的结构......
