將RSS提要轉換為json缺少部分

我正在嘗試將 RSS 提要轉換為 json PHP。我得到了標題、描述等，但我缺少以“itunes”開頭的所有元素。

例如，這沒有顯示在我的 json 中：

<itunes:subtitle>Subtitle text here</itunes:subtitle>

但這些顯示：

<title>Title here</title>
<description>Description here</description>

我認為這與將 XML 轉換為 json 有關，我將此代碼用于：

function Parse($url) {
    $fileContents= file_get_contents($url);
    $fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
    $fileContents = trim(str_replace('"', "'", $fileContents));
    $simpleXml = simplexml_load_string($fileContents);
    $json = json_encode($simpleXml);
    return $json;
}

誰能幫我理解錯誤發生在哪里？

uj5u.com熱心網友回復：

啊，您正在使用正在執行的字串替換破壞 XML。相反，您需要做的就是將其中的標簽轉換為:在轉換為 JSON 后在 PHP 中有效的東西

所以只要做str_replace()轉換

<itunes:subtitle>Subtitle text here</itunes:subtitle>

到

<itunes_subtitle>Subtitle text here</itunes_subtitle>

這將使這些標簽在轉換為 PHP 資料結構時合法

function Parse($url) {
    $fileContents= file_get_contents($url);
    
    $fileContents = str_replace(':', '_', $fileContents);
    
    $simpleXml = simplexml_load_string($fileContents);
    $json = json_encode($simpleXml);
    return $json;
}

結果
