| michael@0 | 36 | Omitting nodes from the logical view of a subtree can result in a structure that |
| michael@0 | 37 | is substantially different from the same subtree in the complete, unfiltered |
| michael@0 | 38 | document. Nodes that are siblings in the TreeWalker view may be children of |
| michael@0 | 39 | different, widely separated nodes in the original view. For instance, consider a |
| michael@0 | 40 | NodeFilter that skips all nodes except for Text nodes and the root node of a |
| michael@0 | 41 | document. In the logical view that results, all text nodes will be siblings and |
| michael@0 | 42 | appear as direct children of the root node, no matter how deeply nested the |
| michael@0 | 43 | structure of the original document. |
