DOMDocument::getElementById - Searches for an element with a certain id

SYNOPSIS

       public DOMElement DOMDocument::getElementById (string  $elementId)

DESCRIPTION

	This function is similar to "DOMDocument::getElementsByTagName" but searches for an element with a given id.

	For  this  function  to  work,	you will need either to set some ID attributes with "DOMElement::setIdAttribute" or a DTD which defines an
       attribute to be of type ID. In the later case, you will need to validate your document with "DOMDocument::validate" or  DOMDocument::$vali-
       dateOnParse before using this function.

PARAMETERS

	      o $elementId
		- The unique id value for an element.

RETURN VALUES

	Returns the DOMElement or NULL if the element is not found.

EXAMPLES

       Example #1

	      DOMDocument::getElementById() Example

	      <?xml version="1.0" encoding="UTF-8"?>

		<!ELEMENT book	  (title, author+, xhtml:blurb?)>

		<!ELEMENT blurb   (#PCDATA)>
		<!ELEMENT author  (#PCDATA)>
		<!ATTLIST books   xmlns        CDATA  #IMPLIED>
		<!ATTLIST books   xmlns:xhtml  CDATA  #IMPLIED>
		<!ATTLIST book	  id	       ID     #IMPLIED>

	      <?php

	      // We need to validate our document before refering to the id
	      $doc->validateOnParse = true;
	      $doc->Load('book.xml');

	      echo "The element whose id is 'php-basics' is: " . $doc->getElementById('php-basics')->tagName . "
