domdocument.getelementbyid
DOMDOCUMENT.GETELEMENTBYID(3) 1 DOMDOCUMENT.GETELEMENTBYID(3)
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
The following examples use book.xml which contains the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE books [
<!ELEMENT books (book+)>
<!ELEMENT book (title, author+, xhtml:blurb?)>
<!ELEMENT title (#PCDATA)>
<!ELEMENT blurb (#PCDATA)>
<!ELEMENT author (#PCDATA)>
<!ATTLIST books xmlns CDATA #IMPLIED>
<!ATTLIST books xmlns:xhtml CDATA #IMPLIED>
<!ATTLIST book id ID #IMPLIED>
<!ATTLIST author email CDATA #IMPLIED>
]>
<?xml-stylesheet type="text/xsl" href="style.xsl"?>
<books xmlns="http://books.php/" xmlns:xhtml="http://www.w3.org/1999/xhtml">

<?php
$doc = new DomDocument;
// 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 . "
";
?>
The above example will output:
The element whose id is 'php-basics' is: book
