我有一个遍历 xml 的 foreach 循环。我知道如何在 SSIS 中添加这种 foreach。但无法找到相同的biml代码片段。

如何在 biml 中的 foreachloopcontainer 中提及以下属性

枚举器= Foreach 节点列表枚举器

DocumentSourceType=变量

文件来源

枚举类型 = 节点文本

OuterXPathStringSourceType= DirectInput

OuterXPathString = /ROOT/*

对于使用 nodelist 枚举器编写 foreachloopcontainer 的示例代码的任何帮助将是一个巨大的帮助！

如果您想使用变量作为输入源，那么您正在寻找VariableInput

EnumerationType暴露在ForEachNodeListLoop

DirectOuterXPath是您指定 OuterXPathStringSource 的地方，例如<DirectOuterXPath>/ROOT/*</DirectOuterXPath>

虽然不是您请求的准确表示（我全面使用变量），但将其分解<Files><File>Foo.txt</File><File>Bar.txt</File><File>Blee.txt</File></Files>为 Foo.txt、Bar.txt 和 Blee.txt
