XSLT3.0断言和迭代后的异常抛出

Question

我有包含依赖组件的XSLT模块:迭代、验证和…。

输入示例port1.xml

<valuationDocument>
  <valuationSet id="val1">
    <assetValuation>
      <objectReference href="tid-1" />
      <quote>
        <value>1000000</value>
        <sensitivitySet>
          <sensitivity name="SEP21">0.707</sensitivity>
          <sensitivity name="2Y">1.82</sensitivity>
          <sensitivity name="3Y">2.73</sensitivity>
          <sensitivity name="4Y">3.68</sensitivity>
          <sensitivity name="5Y">4.51</sensitivity>
          <sensitivity name="7Y">3.64</sensitivity>
          <sensitivity name="10Y">9.06</sensitivity>
          <sensitivity name="MAR21">0.315</sensitivity>
          <sensitivity name="15Y">13.59</sensitivity>
        </sensitivitySet>
      </quote>
    </assetValuation>
    <assetValuation>
      <objectReference href="tid-2" />
      <quote>
        <value>1100000</value>
        <sensitivitySet>
          <sensitivity name="SEP21">0.947</sensitivity>
          <sensitivity name="MAR21">0.502</sensitivity>
          <sensitivity name="2Y">1.91</sensitivity>
          <sensitivity name="3Y">2.84</sensitivity>
          <sensitivity name="4Y">3.72</sensitivity>
          <sensitivity name="5Y">4.63</sensitivity>
          <sensitivity name="7Y">3.71</sensitivity>
          <sensitivity name="10Y">9.15</sensitivity>
          <sensitivity name="15Y">13.64</sensitivity>
        </sensitivitySet>
      </quote>
    </assetValuation>
  </valuationSet>
</valuationDocument>

i对iteration组件(使streaming…失效)相当满意。。迭代结果如下：

<valuationDocument>
   <valuationSet id="val1">
      <assetValuation>
         <objectReference href="tid-1"/>
         <quote>
            <value>1000000</value>
            <BasisPointValue>
               <shiftUp units="100bp" sensitivityName="SEP21" sensitivity="0.707">992,930.00</shiftUp>
               <shiftDown units="100bp" sensitivityName="SEP21" sensitivity="0.707">1,007,070.00</shiftDown>
==========================================================================================
               <shiftUp units="100bp" sensitivityName="15Y" sensitivity="13.59">864,100.00</shiftUp>
               <shiftDown units="100bp" sensitivityName="15Y" sensitivity="13.59">1,135,900.00</shiftDown>
            </BasisPointValue>
            <sensitivitySet>
               <sensitivity name="SEP21">0.707</sensitivity>
               <sensitivity name="2Y">1.82</sensitivity>
               <sensitivity name="3Y">2.73</sensitivity>
               <sensitivity name="4Y">3.68</sensitivity>
               <sensitivity name="5Y">4.51</sensitivity>
               <sensitivity name="7Y">3.64</sensitivity>
               <sensitivity name="10Y">9.06</sensitivity>
               <sensitivity name="MAR21">0.315</sensitivity>
               <sensitivity name="15Y">13.59</sensitivity>
            </sensitivitySet>
         </quote>
      </assetValuation>
      <assetValuation>
        <objectReference href="tid-2" />
           <quote>
              <value>1100000</value>
            <BasisPointValue>
               <shiftUp units="100bp" sensitivityName="SEP21" sensitivity="0.947">1,089,583.00</shiftUp>
               <shiftDown units="100bp" sensitivityName="SEP21" sensitivity="0.947">1,110,417.00</shiftDown>
==========================================================================================
               <shiftUp units="100bp" sensitivityName="15Y" sensitivity="13.64">949,960.00</shiftUp>
               <shiftDown units="100bp" sensitivityName="15Y" sensitivity="13.64">1,250,040.00</shiftDown>
            </BasisPointValue>
            <sensitivitySet>
               <sensitivity name="SEP21">0.947</sensitivity>
               <sensitivity name="MAR21">0.502</sensitivity>
               <sensitivity name="2Y">1.91</sensitivity>
               <sensitivity name="3Y">2.84</sensitivity>
               <sensitivity name="4Y">3.72</sensitivity>
               <sensitivity name="5Y">4.63</sensitivity>
               <sensitivity name="7Y">3.71</sensitivity>
               <sensitivity name="10Y">9.15</sensitivity>
               <sensitivity name="15Y">13.64</sensitivity>
            </sensitivitySet>
         </quote>
      </assetValuation>
   </valuationSet>
</valuationDocument>

我想在迭代结果完成后立即验证它。如果任何验证失败，则报告异常并终止程序。但是，验证在迭代之后并不是。(实际的验证是通过xsl:try|catch引发异常，如果任何断言失败，则终止)验证逻辑是将sensitivitySet/sensitivity的三种指标与迭代和转换的BasisPointValue/shiftUp|shiftDown/@sensitivity进行比较(注意: xsl:text是模拟异常抛出，显然XSLT编辑器无法发出消息)

    <xsl:variable name="MinE">
        <!-- <xsl:message terminate="yes">Fatal Error: Minimum NPV and BPV sensitivity is different</xsl:message>-->
        <xsl:text>&#x9;&#xA;</xsl:text>
        <xsl:text>Retro: Min NPV and BPV sensitivity</xsl:text>
        <xsl:text>&#x9;&#xA;</xsl:text>
    </xsl:variable> 
    <xsl:variable name="MaxE">
        <!--<xsl:message terminate="yes">Fatal Error: Maximum NPV and BPV sensitivity is different</xsl:message>-->
        <xsl:text>&#x9;&#xA;</xsl:text>
        <xsl:text>Retro: Max NPV and BPV sensitivity</xsl:text>
        <xsl:text>&#x9;&#xA;</xsl:text>
    </xsl:variable> 
    <xsl:variable name="AvgDownE">
        <!--<xsl:message terminate="yes">Fatal Error: Average NPV and BPV ShiftDown sensitivity is different</xsl:message>-->

迭代后的XSLT3.0验证解决方案是什么？

Answer 1

如果我正确理解这个问题，这是一个标准的多相转换。您可以使用两个单独的样式表，使用一些外部API将它们链接在一起(例如shell脚本、Ant/gradle、XProc、Java应用程序)，也可以使用逻辑将两个阶段放在同一个样式表中。

<xsl:variable name="temp">
  <xsl:apply-templates select="/" mode="phase-1"/>
</xsl:variable>
<xsl:apply-templates select="$temp" mode="phase-2"/>
