Troubles with parsing XML document

programming
1

Hello there,

I’m new here and i have a question about an articele on this site.
I fount this article about[FONT=Verdana][SIZE=2][COLOR=#003366][COLOR=Black]XML Parsing using PHP {Intermediate} by google[/COLOR][/COLOR][/SIZE][/FONT].
The articele is pretty good! Did’nt found anything like it elsewere, thanks fot that!

But i have a problem. I use the code on the page to display my weekly Last.fm charts on my website, but for that i need to get another value from the XML document. I need the URL of the artistpage on last.fm. I modified the script a little but assuming that this should work but instead i get this output:

<ol>
<li><a href="" title="T.I. &ndash; Music at Last.fm">T.I.</a> - 58</li>
<li><a href="http://www.last.fm/music/T.I." title=" &ndash; Music at Last.fm"></a> - </li>
<li><a href="" title="Jedi Mind Tricks &ndash; Music at Last.fm">Jedi Mind Tricks</a> - 56</li>
<li><a href="http://www.last.fm/music/Jedi+Mind+Tricks" title=" &ndash; Music at Last.fm"></a> - </li>
<li><a href="" title="The Game &ndash; Music at Last.fm">The Game</a> - 35</li>
<li><a href="http://www.last.fm/music/The+Game" title=" &ndash; Music at Last.fm"></a> - </li>
<li><a href="" title="Juelz Santana &ndash; Music at Last.fm">Juelz Santana</a> - 31</li>
<li><a href="http://www.last.fm/music/Juelz+Santana" title=" &ndash; Music at Last.fm"></a> - </li>
<li><a href="" title="Wolfgang Amadeus Mozart &ndash; Music at Last.fm">Wolfgang Amadeus Mozart</a> - 27</li>
<li><a href="http://www.last.fm/music/Wolfgang+Amadeus+Mozart" title=" &ndash; Music at Last.fm"></a> - </li>
</ol>

While the url should come just in the href attribute. What did i do wrong? I don’t see it anymore. I now have this code:

<?php
  $xml_file  = "http://ws.audioscrobbler.com/1.0/user/Maurice-k/weeklyartistchart.xml";

  $xml_artist_name_key = "*WEEKLYARTISTCHART*ARTIST*NAME";
  $xml_artist_play_key = "*WEEKLYARTISTCHART*ARTIST*PLAYCOUNT";
  $xml_artist_url_key = "*WEEKLYARTISTCHART*ARTIST*URL";

  $story_array = array();

  $counter = 0;
  class xml_story{
    var $name, $play, $url;
  }

  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);
  }

  function contents($parser, $data){
    global $current_tag, $xml_artist_name_key, $xml_artist_play_key, $xml_artist_url_key, $counter, $story_array;
    switch($current_tag){
      case $xml_artist_name_key:
        $story_array[$counter] = new xml_story();
        $story_array[$counter]->name = $data;
      break;
      case $xml_artist_play_key:
        $story_array[$counter]->playcount = $data;
        $counter++;
      break;
      case $xml_artist_url_key:
        $story_array[$counter]->url = $data;
        $counter++;
      break;
    }
  }

  $xml_parser = xml_parser_create();

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

  xml_set_character_data_handler($xml_parser, "contents");

  $fp = fopen($xml_file, "r") or die("Could not open file");

  $data = fread($fp, 4096) or die("Could not read file");

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

  xml_parser_free($xml_parser);

  fclose($fp); 

  echo("<ol>
");
  for($x=0;$x<10;$x++){
    echo("<li><a href=\"".$story_array[$x]->url."\" title=\"".$story_array[$x]->name." &ndash; Music at Last.fm\">".$story_array[$x]->name."</a> - ".$story_array[$x]->playcount."</li>
");
  } 
?>
</ol>

I hope anyone sees the problem cuz i’m pretty much freakin’out now!

Thanks!
