XSLT - 比较和组合两个 XML 文件

Question

我有一个相当复杂的XML文件和一个更简单的文件，其中包含对复杂文件的一些更正。

复杂元素中的一个元素：

<h1:Document DocKey="obj     40020528">
      <h1:Block Type="obj"
                CreationDate="20.03.2014 09:39:50"
                CreatorID="Admin"
                ChangeDate="21.01.2015 14:40:51"
                ChangerID="Admin"
                OwnerID="Admin"
                FieldsCount="17">
         <h1:Field Type="5000" Value="40020528"/>
         <h1:Field Type="5060" Value="Aufnahme">
            <h1:Field Type="5064" Value="unbekannt"/>
         </h1:Field>
         <h1:Field Type="ob28" Value="Verwalter">
            <h1:Field Type="2864" Value="Köln"/>
            <h1:Field Type="2900"
                      Value="Theaterwissenschaftliche Sammlung, Universität zu Köln"/>
            <h1:Field Type="2930" Value="Fotoabteilung"/>
            <h1:Field Type="2950" Value="TWS_FGL00541"/>
            <h1:Field Type="907d" Value="No: 4260"/>
         </h1:Field>
         <h1:Field Type="ob26" Value="Aufnahmeort">
            <h1:Field Type="2664" Value="unbekannt"/>
            <h1:Field Type="2690" Value="Theater"/>
            <h1:Field Type="2700" Value="Theater unbekannt"/>
         </h1:Field>
         <h1:Field Type="ob30" Value="Herstellung">
            <h1:Field Type="3100" Value="unbekannt"/>
            <h1:Field Type="3475" Value="Fotograf/in, Atelier"/>
         </h1:Field>
         <h1:Field Type="5007" Value="Darstellung">
            <h1:Field Type="5009" Value="unbekannt"/>
            <h1:Field Type="5010" Value="Autor/in"/>
            <h1:Field Type="5013" Value="xTITELx"/>
         </h1:Field>
         <h1:Field Type="ob40" Value="Inszenierung">
            <h1:Field Type="4100" Value="unbekannt"/>
            <h1:Field Type="4475" Value="Regie"/>
         </h1:Field>
         <h1:Field Type="ob40" Value="Inszenierung">
            <h1:Field Type="4100" Value="unbekannt"/>
            <h1:Field Type="4475" Value="Bühnenbild"/>
         </h1:Field>
         <h1:Field Type="5200" Value="Fritz Feinhals"/>
         <h1:Field Type="5220" Value="Fotografie"/>
         <h1:Field Type="5230" Value="Negativ"/>
         <h1:Field Type="5240" Value="Glasplattennegativ"/>
         <h1:Field Type="5360" Value="18x13"/>
         <h1:Field Type="55th" Value="Feinhals, Fritz"/>
      </h1:Block>
   </h1:Document>

简单元素中的一个元素：

<signatur id="TWS_FGL00541">
      <datum/>
      <ort/>
      <ortsteil/>
      <titel>Fritz Feinhals als Wotan</titel>
      <fotograf/>
      <komponist>Wagner, Richard</komponist>
      <author/>
      <regie/>
      <buehnenbild/>
      <darPerson/>
      <freiText>Walküre</freiText>
   </signatur>

我正在尝试比较每个"签名"的两个文档的元素。 如果签名相同，则进行更正。如果有更正，则必须检查来自较简单XML的哪些子元素必须放入复杂元素的子元素中，因此必须检查简单元素的子元素中是否有值，如果是，则该值必须放置在复杂元素中的特定元素中。

我不知道，最好的方法是什么。我正在尝试如下：

<xsl:template name="alles" match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
</xsl:template>
<xsl:variable name="Halft" select="document('simpleOne.xml')" />
<xsl:variable name="Sig_Halft" select="preceding-sibling::$Halft/document/signatur" />
<xsl:variable name="Sig_HiDA" select="preceding-sibling::DocumentSet/Document/Block/Field[@Type='ob28']/Field[@Type='2950']/@Value" />

<!-- <xsl:variable name="" select="" /> -->
<xsl:template match="DocumentSet/Document">
    <xsl:if test="$Sig_HiDA = $Sig_Halft"> <!-- wenn signatur gleich -->
        xcbcvncvn
        <!-- Datum -->
        <xsl:if test="((DocumentSet/Document/Block/Field[@Type='5060']/Field[@Type='5064']/@Value != '') or (DocumentSet/Document/Block/Field[@Type='5060']/Field[@Type='5064']/@Value != $Halft/document/signatur/datum))">
        </xsl:if>
        <!-- Ort -->
        <xsl:if test="((DocumentSet/Document/Block/Field[@Type='ob26']/Field[@Type='2664']/@Value != '') or (DocumentSet/Document/Block/Field[@Type='ob26']/Field[@Type='2664']/@Value != $Halft/document/signatur/ort))">
        </xsl:if>
        <!-- Ortsteil(Theater) -->
        <xsl:if test="((DocumentSet/Document/Block/Field[@Type='ob26']/Field[@Type='2700']/@Value != '') or (DocumentSet/Document/Block/Field[@Type='ob26']/Field[@Type='2700']/@Value != $Halft/document/signatur/ortsteil))">
        </xsl:if>

到目前为止，此转换只关心具有@type="3475"字段，因为我可以轻松地将其映射到新值。这个想法是为signatur的其他孩子创建类似的模板。

注意：我将两个h1:Document节点包装在h1:DocumentSet中，以防您需要一次处理多个"文档"。同样，我在 simpleOne.xml 中创建了一个包装器元素。如果您逐个处理文件，应该很容易删除它。此外，我用通配符对命名空间进行了万无一失的验证——这绝对不是最佳实践，请尝试正确使用它们。
