|
|
Omitting nodes from the logical view of a subtree can result in a structure that
|
|
is substantially different from the same subtree in the complete, unfiltered
|
|
document. Nodes that are siblings in the TreeWalker view may be children of
|
|
different, widely separated nodes in the original view. For instance, consider a
|
|
NodeFilter that skips all nodes except for Text nodes and the root node of a
|
|
document. In the logical view that results, all text nodes will be siblings and
|
|
appear as direct children of the root node, no matter how deeply nested the
|
|
structure of the original document.
