php XML DOM 将特殊字符转换为 &#xYY; [英] php XML DOM translates special chars to &#xYY;

问题描述

我用 AJAX POST 发送:

I send this with AJAX POST:

<li><ul class   "zone zCentral ui-sortable"><li><ul class="region rCol3 ui-sortable"><li class="" style=""><div><span class="tc tc_video">574081</span> <span>video: 'Mundo.Hoy': ¿Dónde habré olvidado... mi memoria?</span></div></li></ul></li></ul></li>

我这样做是为了创建 XML:

I do this to create XML:

        header('Content-type: text/html; charset=utf-8');       
    if(isset($_POST) && isset($_POST['data']))
    {           
        $data = '<ul id="zone_container" class="ui-sortable">';
        $data .= $_POST['data'];
        $data .= '</ul>';                           

        $dom = new DOMDocument('1.0', 'utf-8');
        $dom->loadXML($data);

        echo $dom->saveXML();                       
        exit();
    }

我明白了:

<?xml version="1.0"?>
<ul id="zone_container" class="ui-sortable">
    <li><ul class="zone zCentral ui-sortable"><li><ul class="region rCol3         ui-sortable"><li class="" style=""><div><span class="tc tc_video">574081</span>     <span>video: 'Mundo.Hoy': &#xBF;D&#xF3;nde habr&#xE9; olvidado... mi memoria?</span></div>    </li></ul></li></ul></li></ul>

¿Dónde habré olvidado... mi memoria?

¿Dónde habré olvidado... mi memoria?

翻译成:

¿Dónde habr&#xE9 ; olvidado... mi memoria?

我需要 XML 中的原始字符，这些是 utf-8 有效的，我不知道这种编码的原因:(

I need original chars in the XML, these are utf-8 valid and i don't know the reason for this encode :(

推荐答案

解决此问题的最简单方法是在加载 XML 之后设置编码类型:

The easiest way to fix this is to set the encoding type after you have loaded the XML:

$dom = new DOMDocument();
$dom->loadXML($data);
$dom->encoding = 'utf-8';

echo $dom->saveXML();                       
exit();

您也可以通过在数据的开头放置 XML 声明来修复它:

You can also fix it by putting an XML declaration at the beginning of your data:

$data = '<?xml version="1.0" encoding="utf-8"?>' . $data;
$dom = new DOMDocument();
$dom->loadXML($data);

echo $dom->saveXML();
exit();
