XSLT Muenchian 分组来自 BizTalk WCF-SQL Adapter Schema by ID across groups
XSLT Muenchian grouping from BizTalk WCF-SQL Adapter Schema by ID across groups
我正在开发一个 BizTalk 应用程序，该应用程序使用 WCF SQL 适配器从数据库执行类型化轮询。在研究了如何将生成的模式中的数据分组到我的规范模式之后，我发现 Muenchian Grouping 是常见的解决方案。但是，我很难弄清楚如何将它应用到我的情况中。
基本上，我正在轮询的数据分布在多个表中，这些表混合了一对一和一对多关系，这些关系在所有表中共享相同的主键。由于一对多关系，我无法使用单个 SELECT 语句从各个表中提取所有数据，而是选择在我的轮询数据语句中将其拆分为 生成了下图中显示的源模式。
我想做的只是通过 "SharedID" 将所有记录从我的源模式中分离出来，并将它们放入目标模式中的适当记录中。 （我也有子组的辅助实例编号 ID，但我想这些将以相同的方式解决。）我看到的所有示例都展示了当 XSLT 密钥派生自 single node or multiple nodes 时如何执行此操作来自源模式，但它们没有显示如何解释同一 ID 何时来自多个节点。
我已经尽我所能分析了来自许多来源的示例，但我对 XSLT 还是个新手，所以我很难弄清楚如何设置我的键和 for-each 语句以适应这种方法。任何帮助揭开我应该如何去做的神秘面纱将不胜感激。谢谢！
这是使用我的源和目标模式结构的通用版本的地图的屏幕截图。
这是上面的地图生成的 XSLT，我将其用作起点。

根据 Johns-305 的建议，我查看了 Muenchian 分组的替代方案，并得出了下面的解决方案，它似乎按预期工作。在研究了 Muenchian 方法之后，我似乎给了自己狭隘的视野。最终结果确实容易多了，但我对 XSLT 的缺乏经验使它不太明显。
当然，如果有人知道更好的方法或看到任何改进的余地，请随时提出其他建议。在接受这个答案之前，我会把这个问题开放几天，以防出现更好的答案。谢谢！

我正在开发一个 BizTalk 应用程序，该应用程序使用 WCF SQL 适配器从数据库执行类型化轮询。在研究了如何将生成的模式中的数据分组到我的规范模式之后，我发现 Muenchian Grouping 是常见的解决方案。但是，我很难弄清楚如何将它应用到我的情况中。
基本上，我正在轮询的数据分布在多个表中，这些表混合了一对一和一对多关系，这些关系在所有表中共享相同的主键。由于一对多关系，我无法使用单个 SELECT 语句从各个表中提取所有数据，而是选择在我的轮询数据语句中将其拆分为
我想做的只是通过 "SharedID" 将所有记录从我的源模式中分离出来，并将它们放入目标模式中的适当记录中。 （我也有子组的辅助实例编号 ID，但我想这些将以相同的方式解决。）我看到的所有示例都展示了当 XSLT 密钥派生自 single node or multiple nodes 时如何执行此操作来自源模式，但它们没有显示如何解释同一 ID 何时来自多个节点。
我已经尽我所能分析了来自许多来源的示例，但我对 XSLT 还是个新手，所以我很难弄清楚如何设置我的键和 for-each 语句以适应这种方法。任何帮助揭开我应该如何去做的神秘面纱将不胜感激。谢谢！
这是使用我的源和目标模式结构的通用版本的地图的屏幕截图。
这是上面的地图生成的 XSLT，我将其用作起点。

根据 Johns-305 的建议，我查看了 Muenchian 分组的替代方案，并得出了下面的解决方案，它似乎按预期工作。在研究了 Muenchian 方法之后，我似乎给了自己狭隘的视野。最终结果确实容易多了，但我对 XSLT 的缺乏经验使它不太明显。
当然，如果有人知道更好的方法或看到任何改进的余地，请随时提出其他建议。在接受这个答案之前，我会把这个问题开放几天，以防出现更好的答案。谢谢！
