PHP Array & XML Can't get all content - php

Question

I'm tring to get all content from this xml: https://api.eveonline.com/eve/SkillTree.xml.aspx
To save it on a MySQL DB.
But there are some data missing...
Could any1 that understand PHP, Array() and XML help me, please?
This is my code to get the content:
<?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>';
?>
If you go to the original XML (link), at line 452, you will see:
<row groupName="Spaceship Command" groupID="257">
And that isn't show in my array (link)...
That is one thing that i found that is missing...
I think that probally have more content that is missing too..
Why? How to fix it, please?
Thank you!!!

You will only get a total of sizeof($xmlbalance->result->rowset->row) records. Because, in your 2nd for loop, you are basically storing your result in the same array element that is $skills[$x].
Try this (I also higly encourage you to be as lazy as you can when you write code - by lazy I mean, avoid repeating / rewriting the same code over and over if possible) :
$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);
