DomNode->replace_node -- Replaces node

## Description

object DomNode->replace_node ( object newnode)

(PHP 4.2) This function replaces an existing node with the passed new node. Before the replacement `newnode` 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 DomNode_first_child(), DomNode_child_nodes() etc..

(PHP 4.3) This function replaces an existing node with the passed new node. It is not copied anymore. If `newnode` was already inserted in the document it is first unlinked from its existing context. If the replacement succeds the old node is returned.
