Overview

Refer to Working with Data Sets.

Remarks

Updates the CurrentElement property with the last element in the Data Set that has the specified tag. The search begins with the element specified in the CurrentElement property. The results depend on whether the Data Set is evaluated as a tree or a list.

If the Data Set is evaluated as a tree structure, this method updates the CurrentElement property with the last item on the same level and with the same parent as the element specified in the CurrentElement property, that has tag lTag.

For the sake of these illustrations, the order of siblings is top to bottom. Therefore last is the item closest to the bottom.

Please note that the numbering of the items of interest in this first illustration is arbitrary and does not imply order.

If the CurrentElement property contains:

The CurrentElement property will be updated with:

Item 1

The last sibling (same level, same parent) of Item 1 that has tag lTag, if such an item exists. If such an item does not exist, the CurrentElement is updated with NULL.

Item 2

The last sibling (same level, same parent) of Item 2 that has tag lTag, if such an item exists. If such an item does not exist, the CurrentElement is updated with NULL.

Item 3

The last sibling (same level, same parent) of Item 3 that has tag lTag, if such an item exists. If such an item does not exist, the CurrentElement is updated with NULL.

 

If the Data Set is evaluated as a list, this method updates the CurrentElement with the last item in the entire list that has tag lTag. The search begins at the element specified in the CurrentElement property.

For the sake of these illustrations, the order of siblings is top to bottom. Therefore last is closest to the bottom.

Please note that the numbering of the items in this illustration does indicate the order of the items when the Data Set is evaluated as a list.
