php - 尝试使用 php 解析此 xml 提要

Question

我想知道如何用 php 解析这个 xml 提要？

http://www.shinyloot.com/feeds/games_on_sale

我知道我可以用它开始：

$shinyloot = simplexml_load_file('http://www.shinyloot.com/feeds/games_on_sale');

从那里我不确定解析它的最佳方法是它是一种更复杂的方法，其中包含多个数组。

此外，这不是重复，它是一个特定案例，您链接的答案对于此提要不正确，请将其取消标记为重复。

您可以使用来读取属性数据，对于在字母之间带有破折号和其他字符的元素，您可以用大括号和单引号将其括起来，就像我为元素$variable['attribute_name']所做的那样。operating-systems

<?php
$url = 'http://www.shinyloot.com/feeds/games_on_sale';
$xml = simplexml_load_string(file_get_contents($url));
foreach ($xml->games->game as $game)
{
    $operating_system = array();
    foreach ($game->{'operating-systems'}->os as $os)
        $operating_system[] = $os;

    if (!in_array("Linux", $operating_system))
        continue;
    echo "Title: ", $game['title'], "\n";
    echo "URL: ", $game['url'], "\n";
    echo "MRSP: ", $game->mrsp, "\n";
    echo "Price: ", $game->price, "\n";
    echo "Discount: ", $game->{'discount-pct'}, "%\n";
    echo "Cover Image: ", $game->{'cover-image'}, "\n";
    echo "Header Image: ", $game->{'header-image'}, "\n";
    echo "Available for:\n";
    foreach ($operating_system as $os)
    {
        echo $os, "\n";
    }
    echo "==================================================\n\n";
}

另一种方法是这样的：

$operating_system = json_decode(json_encode($game->{'operating-systems'}), true);
if (!in_array("Linux", $operating_system['os']))
   continue;

基本上它将结果转换为 JSON，然后将其转换回简单的关联数组。

好的，这就是我想知道的任何人：

<?php
$url = 'http://www.shinyloot.com/feeds/games_on_sale';
$xml = simplexml_load_string(file_get_contents($url));
foreach ($xml->games->game as $game)
{
    $os_options = array();
    foreach ($game->{'operating-systems'}->os as $os)
    {
        $os_options[] = $os;
    }

    if (in_array("Linux", $os_options))
    {
        echo "Title: ", $game['title'], "\n";
        echo "URL: ", $game['url'], "\n";
        echo "Price: ", $game->price, "\n";
        echo "<br />==================================================<br />";
    }
}

不确定这是否是最好的方法，但这允许我按 os.filter 过滤。

感谢大奖赛。
