php - 如何将 XML 文件转换为 SimpleXMLElement() 数组？

Question

我有一个 XML 文件:

<?xml version="1.0" encoding="iso-8859-1"?>
<deadlines>
    <deadline>
        <date>2010-07-01</date>
        <text>Residency Application for Fall Due</text>
    </deadline>
    <deadline>
        <date>2010-06-01</date>
        <text>Residency Application for Summer Due</text>
    </deadline>
    <deadline>
        <date>2010-07-20</date>
        <text>Summer Bill Due</text>
    </deadline>
</deadlines>

当我使用 simplexml_load_file() 将文件加载到 PHP 脚本中时，我得到以下信息:

SimpleXMLElement Object
(
    [deadline] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [date] => 2010-07-01
                    [text] => Residency Application for Fall Due
                )

            [1] => SimpleXMLElement Object
                (
                    [date] => 2010-06-01
                    [text] => Residency Application for Summer Due
                )

            [2] => SimpleXMLElement Object
                (
                    [date] => 2010-07-20
                    [text] => Summer Bill Due
                )

        )

)

为了让我的脚本将 XML 文件作为数组处理，我需要解析该文件并将其转换为以下格式:

Array
(
    [0] => SimpleXMLElement Object
        (
            [date] => 2010-07-01
            [text] => Residency Application for Fall Due
        )

    [1] => SimpleXMLElement Object
        (
            [date] => 2010-06-01
            [text] => Residency Application for Summer Due
        )

    [2] => SimpleXMLElement Object
        (
            [date] => 2010-07-20
            [text] => Summer Bill Due
        )

)

是否有 PHP 函数可以转换 XML 文件？谢谢

Answer 1

$deadlines = array();
$sxe = new SimpleXmlElement($xml);
foreach($sxe->deadline as $deadline) {
    $deadlines[] = $deadline;
}
print_r($deadlines);

或

$sxe = (array) new SimpleXmlElement($xml);
print_r( $sxe['deadline'] );

编辑抱歉，我假设您对 SimpleXml 足够熟悉，知道 constructor of SimpleXmlElement assumes you are passing the XML as a string 。要么更改行来读取

$sxe = new SimpleXmlElement($filename, NULL, TRUE);

或将其替换为

$sxe = simplexml_load_file($filename);
