来自DomDocument的nodeValue在PHP中返回奇怪的字符 [英] nodeValue from DomDocument returning weird characters in PHP

问题描述

所以，我试图解析HTML页面，并使用 get_elements_by_tag_name（'p'）;查找段落（< p> / code>

So I'm trying to parse HTML pages and looking for paragraphs (<p>) using get_elements_by_tag_name('p');

问题是，当我使用 $ element-> nodeValue 奇怪的字符。使用curl将文档首先加载到$ html中，然后将其加载到DomDocument中。

The problem is that when I use $element->nodeValue, it's returning weird characters. The document is loaded first into $html using curl then loading it into a DomDocument.

我确信它与charsets有关。

I'm sure it has to do with charsets.

下面是一个响应示例：aujourdâ€hui。

Here's an example of a response: "aujourd’hui".

提前感谢。

推荐答案

我有同样的问题，现在注意到loadHTML（）不再需要2个参数，所以我不得不找到一个不同的解决方案。在我的DOM库中使用以下函数，我能够从HTML内容中删除有趣的字符。

I had the same issues and now noticed that loadHTML() no longer takes 2 parameters, so I had to find a different solution. Using the following function in my DOM library, I was able to remove the funky characters from my HTML content.

private static function load_html($html)
{
    $doc = new DOMDocument;
    $doc->loadHTML('<?xml encoding="UTF-8">' . $html);

    foreach ($doc->childNodes as $node)
        if ($node->nodeType == XML_PI_NODE)
            $doc->removeChild($node);

    $doc->encoding = 'UTF-8';

    return $doc;
}
