我可以实现大部分所需的输出，除了少数......

我希望根据对象节点的distName属性对输出进行排序。
我希望排序只发生在类名为Branch、BranchItem、BranchItemPeriod的某些子节点上。
在这里，我尝试使用删除和创建操作进行更新，因此我还想保持删除和创建的顺序，这也是我在当前转换逻辑中所做的，否则会发生这样的情况，即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。

非常感谢任何建议或帮助。

我认为您需要的是与InsideData元素匹配的模板，然后您可以在其中按您需要的顺序选择子对象元素。

您首先要输出非“对象”元素，假设这些元素总是在对象元素之前。

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

然后，您将选择具有所需类属性的对象元素，并按您需要的顺序进行排序：

 <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，看看您是如何开始的：

  <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>
