Simple XML Help

[jadedknight]

So I want to parse through this XML: http://pastebin.com/afPrzED1

 

I want to echo every realm name. I can get the first set of realm names in the first <Battlegroup> block, but I cannot get past those to the others. I'm not really sure how to move on.. maybe child node or something? I have no clue haha. Can anyone help? Below I pasted some ideas I was just messing around with.

 

$armory_xml = simplexml_load_file($url);

echo $armory_xml->battlegroups->battlegroup[0]['ladderUrl'];

foreach ($armory_xml->battlegroups->battlegroup as $bg_name) {
    //echo $bg_name[0]['ladderUrl'];
    foreach ($armory_xml->battlegroups->battlegroup->realms as $realms) {
        foreach($armory_xml->battlegroups->battlegroup->realms->realm as $realm){
            echo $realm[0]['nameEN'];    
        }
    }
}

print_r($armory_xml);

$armory_xml->battlegroups->battlegroup->realms->realm[0]->attributes() as $realm => $realm_name

foreach ($armory_xml->battlegroups->battlegroup as $battlegroup) {
    $i = $battlegroup[0]->['ladderUrl'];
    echo $i;
    foreach ($armory_xml->battlegroups->battlegroup->realms->realm as $realm) {
        echo $realm[0]->attributes() . "   ";
    }   
} 

foreach ($armory_xml->battlegroups->battlegroup as $bg_name) {
    echo $bg_name->realms->realm[0]['nameEN'];
}

foreach ($armory_xml->battlegroups->battlegroup as $bg_name) {
    echo $bg_name[2]->realms->realm[4]['nameEN'];
}

I managed to get it working using this code:

 

<?php
$filename = '/path/to/battlegroups.xml';

if (file_exists($filename)) {
  $xml = simplexml_load_file($filename);
  
  // Print battlegroups
  foreach ($xml->battlegroups->battlegroup as $battlegroup) {
    echo '<h1>' . $battlegroup['display'] . '</h1>';
      
    // Print realms for each battlegroup
    echo '<ul>';
    foreach ($battlegroup->realms->realm as $realm) {
      echo '<li>' . $realm['name'] . '</li>';
    }
    echo '</ul>';
  }
}
?>

Hey thanks! I will take your simplicity and try and work with the rest of the xml for my project

I'm actually going to re-open this with another problem. Here is some more XML I am trying to parse http://pastebin.com/YD7MaiTM

 

Here is my attempt:

$url = "http://www.wowarmory.com/arena-ladder.xml?p=1&ts=2&b=Vindication";
ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
$armory_xml = simplexml_load_file($url);
$page_count = $armory_xml->arenaLadderPagedResult['page'];
while ($armory_xml->arenaLadderPagedResult['page'] <= $armory_xml->arenaLadderPagedResult['maxPage']) {
        $arena_url = "http://www.wowarmory.com/arena-ladder.xml?p=" . $page_count . "&ts=2&b=Vindication";
        $arena_xml = simplexml_load_file($arena_url);
        foreach ($arena_xml->arenaLadderPagedResult->arenaTeams->arenaTeam as $arena_team) {
            if ($arena_team['rating'] < 2000) {
                break;
            } else {
                echo '<p>' . $arena_team['teamUrl'] . '</p>';
            }
        } $page_count + 1;
}

 

The results are paged, so I am trying to go through each page up to a certain point (2000 "team rating"). The problem is, this isn't throwing any errors, so I am not quite sure where I'm going wrong. How could I implement a test(?) to throw some errors. Also, I don't want to get banned because I'm calling so many URLS, how can I implement a wait time? I really appreciate all the help.

 

Reading over it I see some flaws in my logic, just trying to wrap my head around how to page through the results and get what I want.

Umm sorry for adding another reply but it won't let me edit my posts.. tried relogging too. Anyways I updated my PHP slightly:

$url = "http://www.wowarmory.com/arena-ladder.xml?p=1&ts=2&b=Vindication";
ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
$armory_xml = simplexml_load_file($url);
$page_count = $armory_xml->arenaLadderPagedResult['page'];
$max_page = $armory_xml->arenaLadderPagedResult['maxPage'];

while ($page_count <= $max_page) {
        $arena_url = "http://www.wowarmory.com/arena-ladder.xml?p=" . $page_count . "&ts=2&b=Vindication";
        $arena_xml = simplexml_load_file($arena_url);
        foreach ($arena_xml->arenaLadderPagedResult->arenaTeams->arenaTeam as $arena_team) {
            if ($arena_team['rating'] < 2500) {
                break;
            } else {
                echo '<p>' . $arena_team['teamUrl'] . '</p>';
            }
        } $page_count++;
}

 

I changed a few things including the "rating" to stop at since I don't have a wait time implemented yet.

Fixed it myself. If anyone is interested I'll post the solution below:

$url = "http://www.wowarmory.com/arena-ladder.xml?p=1&ts=2&b=Vindication";
ini_set("user_agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
$armory_xml = simplexml_load_file($url);
$page_count = intval($armory_xml->arenaLadderPagedResult['page']);
$max_page = intval($armory_xml->arenaLadderPagedResult['maxPage']);

echo $page_count . '<br />' . $max_page;

while ($page_count <= $max_page) {
        $arena_url = "http://www.wowarmory.com/arena-ladder.xml?p=$page_count&ts=2&b=Vindication";
        $arena_xml = simplexml_load_file($arena_url);
        foreach ($arena_xml->arenaLadderPagedResult->arenaTeams->arenaTeam as $arena_team) {
            if ($arena_team['rating'] < 2500) {
                break;
            } else {
                echo '<p>' . $arena_team['teamUrl'] . '</p>';
            }
        }
        $page_count++;
}
