Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,
Kirupa

Thread: XML Parsing using PHP {Intermediate}

  1. #1

    XML Parsing using PHP {Intermediate}

    This will probably be an easy fix for someone who is familiar with XML. I have gone through the tutorial from this site (XML Parsing using PHP intermediate). Everything is working except for one problem. Every time I refresh my script in my browser, I get a different amount of results. Most times the script only parses 4 results form the xml file but sometimes it parses all 11 results like it should.


    Here is what my code looks like:


    #################################
    ?php

    $xml_file = "http://api.votesmart.org/Candidates.getByOfficeState?key=72b64124ada95f14e3 581b010e133d9b&officeId=5&stateId=UT&electionYear= 2008";


    $xml_id_key = "*CANDIDATELIST*CANDIDATE*CANDIDATEID";
    $xml_ln_key = "*CANDIDATELIST*CANDIDATE*LASTNAME";

    $story_array = array();

    $counter = 0;
    class xml_story{
    var $vs_id, $vs_ln;
    }

    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_id_key, $xml_ln_key, $counter, $story_array;
    switch($current_tag){
    case $xml_id_key:
    //$story_array[$counter] = new xml_story();
    $story_array[$counter]->vs_id = $data;
    break;
    case $xml_ln_key:
    $story_array[$counter]->vs_ln = $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");

    $size = filesize($xml_file);
    $data = fread($fp, 8000) or die("Could not read file");

    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);

    ?>

    }

    echo "<br><br>";

    print_r($story_array);
    echo "<br><br>";
    var_dump($story_array);
    ?>
