  <para>
   (PHP 4.2) This function replaces an existing node with the passed
   new node. Before the replacement
   <parameter>newnode</parameter> 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
   <function>domnode_first_child</function>,
   <function>domnode_child_nodes</function> etc..
  </para>
  <para>
   (PHP 4.3) This function replaces an existing node with the passed new node. It is not
   copied anymore. If <parameter>newnode</parameter>  was already inserted in the document 
   it is first unlinked from its existing context. If the replacement succeeds the old 
   node is returned.
