	3	+The Stack connector is designed to maintain a stack variable containing a list of input files for iterative processing using the 'Loop' connector.

	11	+
	12	+The connector accepts 2 params :
	13	+
	14	+* Variable name : that will be referred to inside the [[Loop connector>>doc:iXPath V3.Connectors.Scenario.Loop.WebHome]]
	15	+* Append : a checkbox, If checked, the files will be added to the end of the stack. Otherwise, they will be prepended.
	16	+
	17	+= Use =
	18	+
	19	+The 'Stack' must be combined with a 'Loop' connector to make it useful, depending on each use case.

	21	+====== Example: ======
	22	+
	23	+[[image:1721397744988-575.png]]
	24	+
	25	+
	26	+we set a variable named 'var', and put the loaded files from 'LoadFile2' as value.
	27	+

	29	+
	30	+
	31	+then, we retrieve this variable using the 'Loop' connector, and iterate over the set, and make a limit of iterations as 20.

	35	+
	36	+
	37	+inside every iteration we add a new file coming from the 'XMLToXML1'. and we chose to append ie add files at the end of the array.
