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.
