 PHP : Function Reference : DOM XML Functions : DomNode->replace_child
nospam
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>";
?>
