我正在字符串中从该xml获取所有内容：https://api.eveonline.com/eve/SkillTree.xml.aspx
将其保存在MySQL数据库中。
但有一些数据缺失。。。
任何一个懂PHP、Array（）和XML的人能帮我吗？
这是我获取内容的代码：
<?php
$filename = 'https://api.eveonline.com/eve/SkillTree.xml.aspx';
$xmlbalance = simplexml_load_file($filename);
$skills = array();
for ($x=0;$x<sizeOf($xmlbalance->result->rowset->row);$x++) {
$groupName = $xmlbalance->result->rowset->row[$x]->attributes()->groupName;
$groupID = $xmlbalance->result->rowset->row[$x]->attributes()->groupID;
for ($y=0;$y<sizeOf($xmlbalance->result->rowset->row[$x]->rowset->row);$y++) {
$skills[$x]["skillID"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->attributes()->typeID;
$skills[$x]["skillName"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->attributes()->typeName;
$skills[$x]["skillDesc"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->description;
$skills[$x]["skillRank"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rank;
$skills[$x]["skillPrimaryAtr"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->requiredAttributes->primaryAttribute;
$skills[$x]["skillSecondAtr"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->requiredAttributes->secondaryAttribute;
$o = 0;
for ($z=0;$z<sizeOf($xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->row);$z++) {
if ($xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->attributes()->name == "requiredSkills") {
$skills[$x]["requiredSkills"]["".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->row[$z]->attributes()->typeID] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->row[$z]->attributes()->skillLevel;
$o++;
}
}
}
}
echo '<pre>'; print_r($skills); echo '</pre>';
?>
如果您转到第452行的原始XML（链接），您将看到：
<row groupName="Spaceship Command" groupID="257">
我的数组（链接）中没有显示。。。
这是我发现的一件缺失的东西。。。我认为这可能也有更多缺失的内容。。
为什么？请问怎么修？
谢谢！！！
您总共只能获得sizeof($xmlbalance->result->rowset->row)条记录。因为，在第二个for循环中，基本上将结果存储在与$skills[$x]相同的数组元素中。
试试这个（我也强烈鼓励你在写代码时尽可能地懒惰——懒惰的意思是，如果可能的话，避免重复/重写相同的代码）：
$filename = 'https://api.eveonline.com/eve/SkillTree.xml.aspx';
$xmlbalance = simplexml_load_file($filename);
$skills = array();
foreach ($xmlbalance->result->rowset->row as $row)
{
$groupName = $row->attributes()->groupName;
$groupID = $row->attributes()->groupID;
foreach ($row->rowset->row as $subRow)
{
$skill['skillID'] = (string) $subRow->attributes()->typeID;
$skill['skillName'] = (string) $subRow->attributes()->typeName;
$skill['skillDesc'] = (string) $subRow->description;
$skill['skillRank'] = (string) $subRow->rank;
$skill['skillPrimaryAtr'] = (string) $subRow->requiredAttributes->primaryAttribute;
$skill['skillSecondAtr'] = (string) $subRow->requiredAttributes->secondaryAttribute;
foreach ($subRow->rowset as $subSubRowset)
{
if ($subSubRowset->attributes()->name == 'requiredSkills')
{
foreach ($subSubRowset->row as $requiredSkill)
{
$skill['requiredSkills'][(string) $requiredSkill->attributes()->typeID] = (string) $requiredSkill['skillLevel'];
}
}
}
$skills[] = $skill;
}
}
print_r($skills);
