示例1: find
/**
* This function removes a node from a tree.
* The function will fail if root node is being removed.
*/
bool
Tree::remove(const ResourceName &elem, bool recursive) {
SearchResult result = find(rootNode, elem, false);
if(result.first == AM_EXACT_MATCH) {
NodeRefPtr delNode = result.second;
// First get the parent.
if(recursive) {
if(delNode->hasSubNodes()) {
delNode->removeAllChildren();
}
} else {

} else {
// if this is the root node we are trying to remove
// the operation must fail.
