How to read data from this XML file with PHP?

建立连接

$Game_ID            = $Game_Search->Game[$i]->id;
$Game_Info_URL      = 'http://thegamesdb.net/api/GetGame.php?id='.$Game_ID;
$Game_Info_Output   = simplexml_load_file($Game_Info_URL);

检索数据示例

$Game_Info_Images = $Game_Info_Output->Game->Images;

关于这个问题，请参阅我想在哪里获得游戏的URL->图像->美术盒A面和B面。我该怎么称呼它？

XML文档（必填字段）

<Data>
    <baseImgUrl>http://thegamesdb.net/banners/</baseImgUrl>
    <Game>
        <Images>
            <boxart side="back" width="1518" height="2148" thumb="boxart/thumb/original/back/90-1.jpg">boxart/original/back/90-1.jpg</boxart>
            <boxart side="front" width="1530" height="2148" thumb="boxart/thumb/original/front/90-1.jpg">boxart/original/front/90-1.jpg</boxart>
        </Images>
    </Game>
</Data>

XML文档（必填字段）

<Data>
    <baseImgUrl>http://thegamesdb.net/banners/</baseImgUrl>
    <Game>
        <Images>
            <boxart side="back" width="1518" height="2148" thumb="boxart/thumb/original/back/90-1.jpg">boxart/original/back/90-1.jpg</boxart>
            <boxart side="front" width="1530" height="2148" thumb="boxart/thumb/original/front/90-1.jpg">boxart/original/front/90-1.jpg</boxart>
        </Images>
    </Game>
</Data>

要读取side="front"width="1530"。。。简单使用；

boxart["Attribute_Name"]

示例：

Game->Images->boxart[$b]["side"] // Gets the side value front/back
Game->Images->boxart[$b]["width"] // gets the width value
Game->Images->boxart[$b]["height"] // gets the height value
Game->Images->boxart[$b]["thumb"] // gets the thumb value

DomDocument和/或Xpath：

$dom = new DOMDocument();
$dom->load('http://thegamesdb.net/api/GetGame.php?id=90');
$xpath      = new DOMXPath($dom);
$baseImgUrl = $xpath->query('//baseImgUrl')->item(0)->nodeValue;
$boxartBackSide  = $xpath->query('//Game/Images/boxart[@side="back"]')
    ->item(0)->nodeValue;
$boxartFrontSide = $xpath->query('//Game/Images/boxart[@side="front"]')
    ->item(0)->nodeValue;
