Iterates over child content nodes or following sibling nodes. Maintains the nodes in document order.

ValueType
ContentMergeIterator

Remarks

  1. Assume that the list I of input nodes is in document order, with no duplicates. There are N nodes in list I.
  2. For each node in list I, derive a list of nodes consisting of matching children or following-sibling nodes. Call these lists S(1)...S(N).
  3. Let F be the first node in any list S(X), where X >= 1 and X < N 4. There exists exactly one contiguous sequence of lists S(Y)...S(Z), where Y > X and Z <= N, such that the lists S(X+1)...S(N) can be partitioned into these three groups: a. 1st group (S(X+1)...S(Y-1)) -- All nodes in these lists precede F in document order b. 2nd group (S(Y)...S(Z)) -- All nodes in these lists are duplicates of nodes in list S(X) c. 3rd group (> S(Z)) -- All nodes in these lists succeed F in document order 5. Given #4, node F can be returned once all nodes in the 1st group have been returned. Lists S(Y)...S(Z) can be discarded. And only a single node in the 3rd group need be generated in order to guarantee that all nodes in the 1st and 2nd groups have already been generated.
