Example – Example for the usage of XML_Parser

Basic example

This example shows you how to create a very simple parser that handles start, end elements (i.e. opening and closing tags), and character data (the "content" between the tags).


<?php
require_once 'XML/Parser.php';

class myParser extends XML_Parser
{
 function myParser()
 {
  parent::XML_Parser();
 }

 /**
 * handle start element
 *
 * @access private
 * @param resource xml parser resource
 * @param string  name of the element
 * @param array   attributes
 */
 function startHandler($xp, $name, $attribs)
 {
  printf('handle start tag: %s<br />', $name);
 }

 /**
 * handle end element
 *
 * @access private
 * @param resource xml parser resource
 * @param string  name of the element
 */
 function endHandler($xp, $name)
 {
  printf('handle end tag: %s<br />', $name);
 }

 /**
 * handle character data
 *
 * @access private
 * @param resource xml parser resource
 * @param string  character data
 */
 function cdataHandler($xp, $cdata)
 {
  // does nothing here, but might e.g. print $cdata
 }
}

$p = &new myParser();

$result = $p->setInputFile('xml_parser_file.xml');
$result = $p->parse();
?>

This parser will just output the names of the opening and closing tags that are found while parsing the document.
