Before the replacement <i><tt class="parameter">newnode</tt></i> is copied if it has a parent to make sure a node which is already in the document will not be inserted a second time. This behaviour enforces doing all modifications on the node before the replacement or to refetch the inserted node afterwards with functions like <a href="function.domnode-first-child.html" class="function">domnode_first_child()</a>, <a href="function.domnode-child-nodes.html" class="function">domnode_child_nodes()</a> etc.. </p> <p class="para"> (PHP 4.3) This function replaces an existing node with the passed new node.
