为嵌套节点编写XSL模板

Question

我有下面的XML结构，它是一个大型XML的简化版本，我需要编写一个XSL模板来从特定的节点(维度)获取数据。

我已经有了一个XSL来完成转换。添加了一个新的节点<Dimensions>，它可以在一个节点内发生多次，如下所示。我需要从general/electronics/tv/description/Dimensions读取数据，并将其内容(div标记内容)输出到最终的HTML中。<Dimensions>也可以发生在software/version/description/Dimensions节点或任何其他节点下。

，所以我的问题是：

是否有一种通用的方法来编写一个模板，该模板可以读取<Dimensions>标记的内容并输出其内容？在编写此标记的XSL模板时，我需要一些帮助。

可以使用XPath表达式检索所需元素的节点
