DomNode->insert_before

(PHP 4 >= 4.1.0)

DomNode->insert_before Inserts new node as child

Описание

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().

Пример #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>";
?>
