DomDocument->document_element

(No version information available, might be only in CVS)

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 );
?>

上例将输出：

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