DomDocument::document_element

(PHP 4 >= 4.1.0)

DomDocument::document_element — Returns root element node

说明

domelement DomDocument::document_element ( void )

This function returns the root element node of a document.

The following example returns just the element with name CHAPTER and prints it. The other node -- the comment -- is not returned.

Example #1 Retrieving root element


<?php
include("example.inc");

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

$root = $dom->document_element();
print_r($root);
?>

以上例程会输出：

domelement Object
(
    [type] => 1
    [tagname] => chapter
    [0] => 6
    [1] => 137960648
)
