Read XML using php

There are many ways to parse XML using php. Below is the code which has been tested & implemented. Just copy and paste this code to read an XML and display in a web form.


 sample.xml

<COMPANY>       
<username>    abbas_kashani    </username>
<username>    abbas_kashani    </username>
<username>    abbas_kashani    </username>
</COMPANY>    

ReadXML.php

class xml_story{
        var $NAME;
    }

$file = "sample.xml";

function contents($parser, $data){
   
    global $current_tag, $xml_description_key1, $counter, $story_array;
       
        switch($current_tag){
         //  echo $current_tag.'^%$<br>';
            case $xml_description_key1:
                $story_array[$counter] = new xml_story();
                $story_array[$counter]->NAME = $data;
                $counter++;
                 break;
               
        }
       
    }

$xml_description_key1 = "*COMPANY*USERNAME";

$counter=0;

function startTag($parser, $data){
        global $current_tag;
        $current_tag .= "*$data";
   
    }
   
    function endTag($parser, $data){
        global $current_tag;
        $tag_key = strrpos($current_tag, '*');
        $current_tag = substr($current_tag, 0, $tag_key);
    }

$xml_parser = xml_parser_create();

xml_set_element_handler($xml_parser, "startTag", "endTag");

xml_set_character_data_handler($xml_parser, "contents");

$fp = fopen($file, "r");

$data = fread($fp, 80000);


if(!(xml_parse($xml_parser, $data, feof($fp)))){
    die("Error on line " . xml_get_current_line_number($xml_parser));
}

xml_parser_free($xml_parser);

fclose($fp);



Below code can be used to iterate through the xml data which has been parsed

for($x=0;$x<count($story_array);$x++)
{
if(strlen($story_array[$x]->NAME) != 0)
echo $story_array[$x]->NAME;
}
