   DicomElement^ element,
   int64 tag,
   bool tree
)

Parameters

element: An item in the Data Set.
tag: Tag of the item to find.
tree: true to evaluate the Data Set as a tree; false to evaluate the Data Set as a list.

Return Value

The last item in the Data Set with the specified Tag, or a null reference (Nothing in Visual Basic) if an item with the specified Tag was not found.

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

If the Data Set is evaluated as a tree structure, this method returns the last item on the same level as element with the same parent as element, that has Tag tag.

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

If the passed object points to:	The method returns an object pointing to:
Item 1	The last sibling (same level, same parent) of Item 1 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. Searching begins at the bottom.
Item 2	The last sibling (same level, same parent) of Item 2 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. Searching begins at the bottom.
Item 3	The last sibling (same level, same parent) of Item 3 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. Searching begins at the bottom.

If the Data Set is evaluated as a list, this method returns the last item in the entire list that has Tag tag. Searching begins at the bottom of the list.

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

If the passed object points to:	The method returns an object pointing to:
Item 1	The last item in the list that has Tag tag, if such an item exists. If an item with Tag tag is not found, null is returned. Searching begins at the bottom.
Item 14	The last item in the list that has Tag tag, if such an item exists. If an item with Tag tag is not found, null is returned. Searching begins at the bottom.
Item 22	The last item in the list that has Tag tag, if such an item exists. If an item with Tag tag is not found, null is returned. Searching begins at the bottom.

The following methods will also help you find elements in the Data Set with a specific Tag:

FindFirstElement

FindPreviousElement

FindNextElement

The following methods will help you find specific modules in the Data Set:

FindModule

FindModuleByIndex

For an example, refer to Load(String,DicomDataSetLoadFlags).
