DOMDocument Function getElementsByTagName

PHP Version: (No version information might be only in CVS. I have used this function in PHP5)

DOM: W3C DOM Level 1

Description

This function searches XML document for a given element name and returns all elements as a DOMNodeList object.

Usage:

object DOMDocument->getElementsByTagName ( string name)

This function returns a new instance of class DOMNodeList containing the elements with tagnames matching the name parameter.

Use "*" for the name to return all elements within the document.

Example:

The XML file, which I have used contains following data. I have stored this file in “c:/topxml_demo/php/xml_files/employee.xml” directory.

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

<employee>

     <employeename id="123456">test</employeename>

     <employeeaddress>test123</employeeaddress>

     <SSN>12343456</SSN>

     <company>TOPXML</company>

     </employee>

PHP Code:

<?php

    $doc = new DomDocument;

// Load the xml file into DOMDocument

$doc->Load('C:/topxml_demo/php/xml_files/employee.xml');

// We retrieve the employeename elements and return the first element.

$employee = $doc->getElementsByTagName('employeename')->item(0);

//Echo out Id attribute of the employee element

echo  "<B> id of employee is</B> :".$employee->getAttribute('id');

 echo "<BR><B>DOMDocument->getElementsByTagName example<B>"

 ?>

Output:
