Question

我仍然试图掌握PHP和XML。我有一个XML，我将截断以节省空间。我想从每个记录中获取维度名称属性 display-name 值。我还必须从每个记录中获取 servermanager 状态值。

我正在使用：

$completeurl = "http://website/data.xml";
$xml = simplexml_load_file($completeurl);
$xml->dimension;

for ($i = 0; $i < 2; $i++) {
    $servername = $dimensions[$i]->attributes()->display-name;
    $status = $dimensions[$i]->servermanager;
};

然而，我得到了：

Fatal error: Call to a member function attributes() on a non-object in the lines I am trying to assign variables.

我正在删除我不想解析的维度之间的所有额外数据。截断的XML是：

<?xml version="1.0"?>
<aostats version="0.6" timestamp="2013-02-13 21:16:01 UTC">
    <dimension name="d1" display-name="Atlantean" loadmax="2" locked="0" players="100%">
        <servermanager status="1"/>
        <clientmanager status="0"/>
        <chatserver status="1"/>
    </dimension>
    <dimension name="d2" display-name="Rimor" loadmax="2" locked="0" players="100%">
        <servermanager status="1"/>
        <clientmanager status="0"/>
        <chatserver status="1"/>
    </dimension>
    <dimension name="dt" display-name="Test" loadmax="2" locked="0" players="100%">
        <servermanager status="1"/>
        <clientmanager status="0"/>
    </dimension>
</aostats>

我通过实验找到了答案：

$completeurl = = "http://website/data.xml";
$xml = simplexml_load_file($completeurl);
$dimensions  = $xml->dimension;
for ($i = 0; $i < 3; $i++) {
$servername = $dimensions[$i]["display-name"];
$status = $dimensions[$i]->servermanager["status"];
}

使用SimpleXML读取属性
