Foreach NodeList Enumerator in biml - ssis

Question

i have a foreach loop which traverse through the xml.
i know how to add this kind of foreach in SSIS. but not able to find the code snippet of biml for the same.
how to mentioned below properties in foreachloopcontainer in biml
Enumerator= Foreach NodeList Enumerator
DocumentSourceType=Variable
DocumentSource
EnumerationType = NodeText
OuterXPathStringSourceType= DirectInput
OuterXPathString = /ROOT/*
any help in having sample code for writing foreachloopcontainer with nodelist enumerator would be a greate help!!!

Answer 1

If you'd like to use a variable as your input source, then you're looking for VariableInput
EnumerationType is exposed in the ForEachNodeListLoop
DirectOuterXPath is where you specify your OuterXPathStringSource, like <DirectOuterXPath>/ROOT/*</DirectOuterXPath>
While not an exact representation of your request (I use Variables across the board), to shred<Files><File>Foo.txt</File><File>Bar.txt</File><File>Blee.txt</File></Files> into Foo.txt, Bar.txt and Blee.txt
