Parsing XML

[dreado]

I’ve been trying to find out how to make a dynamic page displaying info from a xml feed. The explanations I have found have been somewhat confusing. I was wondering if someone here could help me out with this?

Did you create the XML file?

Have you looked through the PHP manual on XML DOM?

Explain "Dynamic" in terms of how you mean it. Do you want a page that updates itself periodically if someone is watching it, or a page that reads from the file automatically?

Hi ober

No, I didn’t create the XML file, it’s one provided by another site.

Not sure if I have seen that manual or not, got a feeling I have but didn’t understand it.

What I’d like to achieve is to display the data from the XML feed in a page of my own, so I can style it to look how I want.

Take a look at [a href=\"http://minixml.psychogenic.com\" target=\"_blank\"]http://minixml.psychogenic.com[/a] which is a fairly light weight class for parsing XML files into an array.

Are you just trying to parse an RSS feed?

Thanks for the link, but in their code, I can't see where you'd put the url of the feed.

Maybe someone can look at the code I initially used and tell me what might be wrong with it (it generates nothing but a blank page).

[code]<?php

function parseIntoArray( $url )
{
    $data = file_get_contents( $url );
    $xml_parser = xml_parser_create();
    xml_parse_into_struct($xml_parser, $data, $vals, $index);
    xml_parser_free($xml_parser);

    $params = array();
    $level = array();
    foreach ($vals as $xml_elem) {
      if ($xml_elem['type'] == 'open') {
       if (array_key_exists('attributes',$xml_elem)) {
         list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);
       } else {
         $level[$xml_elem['level']] = $xml_elem['tag'];
       }
      }
      if ($xml_elem['type'] == 'complete') {
       $start_level = 1;
       $php_stmt = '$params';
       while($start_level < $xml_elem['level']) {
         $php_stmt .= '[$level['.$start_level.']]';
         $start_level++;
       }
       $php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
       eval($php_stmt);
      }
    }
    return $params;
}

function getPlayerData( $url )
{
    $arrayData = parseIntoArray( $url );
    return $arrayData[ "PLAYERDATA" ];
}

$playerData = getPlayerData( "http://bf1942.gametrack.org/player.php?id=2297153&format=xml" );

echo "<pre>";
print_r( $playerData );
echo "</pre>";
?>

<?php echo $playerData["PLAYER"];?> <br />
<?php echo $playerData["GRADE"];?>
