DomNode->insert_before --  Inserts new node as child

Description

object DomNode->insert_before ( object newnode, object refnode)

This function inserts the new node newnode right before the node refnode. The return value is the inserted node. If you plan to do further modifications on the appended child you must use the returned node.

DomNode_insert_before() is very similar to DomNode_append_child() as the following example shows which does the same as the example at DomNode_append_child().

Example 1. Adding a child

include("example.inc");

if(!$dom = domxml_open_mem($xmlstr)) {
  echo "Error while parsing the document\n";
  exit;
}

$elements = $dom->get_elements_by_tagname("informaltable");
print_r($elements);
$element = $elements[0];

$newnode = $element->insert_before($element, $element);
$children = $newnode->children();
$attr = $children[1]->set_attribute("align", "left");

echo "<PRE>";
$xmlfile = $dom->dump_mem();
echo htmlentities($xmlfile);
echo "</PRE>";
