请注意，扩展功能在很大程度上取决于您使用的处理器。在本例中，我使用的是Mircosoft，因此扩展函数的名称空间是urn:schemas microsoft com:xslt。如果您没有使用此功能，则需要找到支持的功能；XSLT很可能用于将一个xml文档转换为另一个xml文档。它不是“数据表示”格式，我不想再谈xsl了。但我认为我们可以在xsl中创建一个组过滤器？您希望输出的文件格式是什么？1）。按董事会+房间数+成人+儿童分组。2） 如果电路板不够，请避免输出该电路板。3） 以董事会最便宜的价格为例，您还没有解释转换必须实现的规则——不要指望XSLT专家熟悉SQL。请编辑问题并提供必要的解释（SQL代码可以省略，因为它很混乱，只占用空间）。
