Answer 1

您可以尝试以下代码：

$xml_data = simplexml_load_file('data.xml');
$xml_data->PRICE = str_replace('.', '', $xml_data->PRICE);

或

$xml_data = simplexml_load_file('data.xml');
$xml_data = json_decode(json_encode($xml_data), true);
$xml_data['PRICE'] = str_replace('.', '', $xml_data['PRICE']);

如果您有多个AUCTION标签，则可以使用以下代码：

$xml_data = simplexml_load_file('data.xml');
$xml_data = json_decode(json_encode($xml_data), true);
foreach($xml_data as &$xml_data_value) {
    $xml_data_value['PRICE'] = str_replace('.', '', $xml_data_value['PRICE']);
}

它起作用了。

Answer 2

一个简单的例子是使用preg_replace_callback

考虑一下包含XML的$str：

$str = <<<S
