Example #1 xml_set_object example

<?php
class CustomXMLParser
{
    private $parser;

    function __construct() 
    {
        $this->parser = xml_parser_create();

        xml_set_object($this->parser, $this);
        xml_set_element_handler($this->parser, "tag_open", "tag_close");
        xml_set_character_data_handler($this->parser, "cdata");
    }

    function parse($data) 
    {
        xml_parse($this->parser, $data);
    }

    function tag_open($parser, $tag, $attributes) 
    {
        var_dump($tag, $attributes); 
    }

    function cdata($parser, $cdata) 
    {
        var_dump($cdata);
    }

    function tag_close($parser, $tag) 
    {
        var_dump($tag);
    }
}

$xml_parser = new CustomXMLParser();
$xml_parser->parse("<A ID='hallo'>PHP</A>");
?>

The above example will output:

string(1) "A"
array(1) {
  ["ID"]=>
  string(5) "hallo"
}
string(3) "PHP"
string(1) "A"
