php - 循环每一项技能，而不仅仅是其中的几个

Question

我正在尝试循环在 EVE Online ( API Skilltree )中可以找到的所有技能，但以下代码仅循环通过前 7 个技能组。

$skilltree_url = file_get_contents('https://api.eveonline.com/eve/SkillTree.xml.aspx', 0, null, null);
$skilltree = simplexml_load_string($skilltree_url);

foreach($skilltree->result->rowset->row AS $skill) {
    var_dump($skill->rowset->row->attributes()->typeID);
}

我做错了什么？

提前致谢。

这段代码：

$xml = simplexml_load_file('https://api.eveonline.com/eve/SkillTree.xml.aspx');
$skilltree = $xml->result->rowset;
foreach($skilltree->row as $skill) {
    var_dump($skill->rowset->row->attributes()->typeID);
}

打印这个：

这应该可以工作，并且更容易使用：

$xml = simplexml_load_file('https://api.eveonline.com/eve/SkillTree.xml.aspx');
$skilltree = $xml->result->rowset;
foreach($skilltree->row as $skill) {
    var_dump($skill->rowset->row->attributes()->typeID);
}

这应该是您需要的全部内容，其余的属性您应该能够自己弄清楚：

$xml = simplexml_load_file('https://api.eveonline.com/eve/SkillTree.xml.aspx');
$skilltree = $xml->result->rowset;
foreach($skilltree->row as $skillgroup) {
    echo 'Group name: ' .$skillgroup->attributes()->groupName .'<br />';
    foreach ($skillgroup->rowset->row as $skill) {
        echo 'Type ID: ' .$skill->attributes()->typeID .'<br />';
        echo 'Type name: ' .$skill->attributes()->typeName .'<br />';
    }
    echo '<br />';
}
