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.
(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().
例子 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>";
?>
