DomNode->insert_before — Inserts new node as child

Description

domelement DomNode->insert_before ( domelement $newnode , domelement $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.

(PHP >= 4.3 only) If newnode already is part of a document, it will be first unlinked from its existing context. If refnode is NULL, then newnode will be inserted at the end of the list of children.

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


<?php

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>";

?>
