'Declaration
 
Public Function FindNextElement( _
   ByVal element As DicomElement, _
   ByVal tree As Boolean _
) As DicomElement

'Usage
 
Dim instance As DicomDataSet

public DicomElement FindNextElement( 
   DicomElement element,
   bool tree
)

ObjectiveC Syntax

 function Leadtools.Dicom.DicomDataSet.FindNextElement( 
   element ,
   tree 
)

public:
DicomElement^ FindNextElement( 
   DicomElement^ element,
   bool tree
)

Parameters

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

Return Value

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

Note: This method does not specify a Tag to use when searching. However the tag that was used in the last call to FindFirstElement or FindLastElement is used by default when searching.

For the sake of the following illustrations, the order of siblings is top to bottom.

If the Data Set is evaluated as a tree structure, this method returns the next 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 next 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.
Item 2	The next 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.
Item 3	The next 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.

If the Data Set is evaluated as a list, this method returns the next item in the entire list that has tag tag.

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 next 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.
Item 14	The next 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.
Item 22	The next 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.

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

FindFirstElement

FindLastElement

FindPreviousElement

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

FindModule

FindModuleByIndex

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

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
