Hi,
The commonly used node functions in real scenarios
1.SplitByValue:
The SplitByValue() function is the counterpart to removeContexts(): Instead of deleting a context, you can insert a context change in the source value queue. You then receive this element for each inserted context change instead of a top node element. However, for this to be possible, the top node source field must be assigned a top node target field and minOccurs must be >0. You can insert a context change in the queue after each value, after each change to the value, or after each tag without a value.
2.RemoveContexts:
You use removeContexts () to delete all the top contexts for an element. This removes all top hierarchy levels, so that all elements of the target queue are assigned to a root element of the source queue.
Advanced user-defined functions can import either just one context into the input arrays, or complete queues. Make your selection by selecting or deselecting the Save Entire Queue in Cache checkbox in the function editor.
3.CreateIf:
CreateIf node function is used to create a node if true value is passed to it otherwise suppress it.
4.collapseContext
To remove the context in between the value and transfer only one value at a time
5.: useOneAsMany
First Input:
The value which is needed to be repeated.
Second Input:
It defines how many times the first input should be repeated.
Third Input:
It define when the context should be changed (on the basis of the required output
