# Example

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).

    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 start 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.
