Public Methods

Method	Description
Create ( XmlNavigatorFilter filter ) : void	Initialize the XPathPrecedingMergeIterator (merge multiple sets of preceding nodes in document order and remove duplicates).
MoveNext ( XPathNavigator input ) : IteratorResult	Position this iterator to the next preceding node in document order. Discard all input nodes that are followed by another input node in the same document. This leaves one node per document from which the complete set of preceding nodes can be derived without possibility of duplicates. Return IteratorResult.NeedInputNode if the next input node needs to be fetched first. Return IteratorResult.HaveCurrent if the Current property is set to the next node in the iteration.

Private Methods

Method	Description
PushAncestors ( ) : void	Push all ancestors of this.navCurrent onto a stack. The set of preceding nodes should not contain any of these ancestors.
