Thanks Daniel. I did some tests for xmlSaveTree, it basically prints out the selected nodes and their children.
Is there any way to print out the selected nodes and their parents (till root)? I can certainly do the traversal via node->parent. Just in case you already have some API available (which will trim the non-selected nodes from the original doc and do xmlDocDump(stdout, doc)).
