DomNode::replace_child

Replaces a child

&reftitle.description; `domelement` `DomNode::replace_child` `domelement` `newnode` `domelement` `oldnode`

(PHP 4.2) This function replaces the child `oldnode` with the passed new node. If the new node is already a child it will not be added a second time. If the old node cannot be found the function returns &false;. If the replacement succeeds the old node is returned.

(PHP 4.3) This function replaces the child `oldnode` with the passed `newnode`, even if the new node already is a child of the DomNode. If `newnode` was already inserted in the document it is first unlinked from its existing context. If the old node cannot be found the function returns &false;. If the replacement succeeds the old node is returned. (This behaviour is according to the W3C specs).
