DomNode->replace_child

Replaces a child ()
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).

There's a bug in the docs here. The order of arguments is the other way round i.e. object DomNode->replace_child ( object newnode, object oldnode) Here's an example of it working: <?php $doc = domxml_new_doc("1.0"); $root = $doc->create_element("HTML"); $doc->append_child($root); $head = $doc->create_element("HEAD"); $root->append_child($head); $title = $doc->create_element("TITLE"); $head->append_child($title); $text = $doc->create_text_node("This is the title"); $title->append_child($text); echo "<PRE>"; echo htmlentities($doc->dump_mem(true)); echo "</PRE>"; $newtitle = $doc->create_text_node("No, this is the title"); // object DomNode->replace_child ( object newnode, object oldnode) $title->replace_child($newtitle,$title->first_child()); echo "<PRE>"; echo htmlentities($doc->dump_mem(true)); echo "</PRE>"; ?>
