我可以获得大部分所需的输出，除了少数......

  1. 我希望根据对象节点的 distName 属性对输出进行排序。
  2. 我希望排序只发生在类名为分支， BranchItem ， BranchItemPeriod 的某些子节点上。
  3. 此处我尝试使用删除和创建操作更新，因此我还希望维持删除的顺序我现在在转换逻辑中执行strong>和创建，否则就会发生这种情况，我首先根据上述标准对所有内容进行排序并应用其他转换逻辑。

    4. 非常感谢任何建议或帮助。

我认为您需要的是一个与 InsideData 元素匹配的模板，然后您可以按照所需的顺序选择子对象元素。

首先输出非“对象”元素，假设它们始终位于对象元素之前。

 <xsl:apply-templates select="@*|node()[not(self::x:object)]"/>

然后，您可以选择具有所需类属性的对象元素，并按您需要的顺序排序：

 <xsl:apply-templates select="x:object[@class='Branch' or @class='BranchItem' or @class='BranchItemPeriod']">
    <xsl:sort select="@distName"/>
 </xsl:apply-templates>

最后，您将输出具有类属性的对象元素。

 <xsl:apply-templates select="x:object[not(@class='Branch' or @class='BranchItem' or @class='BranchItemPeriod')]"/>

尝试将此模板添加到您的XSLT中以了解您的使用方式：

  <xsl:template match="x:InsideData">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()[not(self::x:object)]"/>
      <xsl:apply-templates select="x:object[@class='Branch' or @class='BranchItem' or @class='BranchItemPeriod']">
        <xsl:sort select="@distName"/>
      </xsl:apply-templates>
      <xsl:apply-templates select="x:object[not(@class='Branch' or @class='BranchItem' or @class='BranchItemPeriod')]"/>
    </xsl:copy>
  </xsl:template>
