PHP nodeValue剥离html标签 - innerHTML替代？ [英] PHP nodeValue strips html tags - innerHTML alternative?

问题描述

我正在使用以下脚本来轻量级的DOM编辑器。但是，中的 nodeValue 正在将我的html标签转换为纯文本。

I'm using the following script for a lightweight DOM editor. However, nodeValue in my for loop is converting my html tags to plain text. What is a PHP alternative to nodeValue that would maintain my innerHTML?

$page = $_POST['page'];
$json = $_POST['json'];

$doc = new DOMDocument();
$doc = DOMDocument::loadHTMLFile($page);

$xpath = new DOMXPath($doc);
$entries = $xpath->query('//*[@class="editable"]');
$edits = json_decode($json, true);
$num_edits = count($edits);

for($i=0; $i<$num_edits; $i++) 
{
    $entries->item($i)->nodeValue = $edits[$i]; // nodeValue strips html tags
}

$doc->saveHTMLFile($page);

推荐答案

由于 $ edits [$ i] 是一个字符串，您需要将其解析为DOM结构，并使用新结构替换原始内容。

Since $edits[$i] is a string, you need to parse it into a DOM structure and replace the original content with the new structure.

下面的代码片段使用非XML兼容的HTML做了不可思议的工作。 （例如 HTML 4/5）

The code fragment below does an incredible job when using non-XML compliant HTML. (e.g. HTML 4/5)

for($i=0; $i<$num_edits; $i++)
{
    $f = new DOMDocument();
    $edit = mb_convert_encoding($edits[$i], 'HTML-ENTITIES', "UTF-8"); 
    $f->loadHTML($edit);
    $node = $f->documentElement->firstChild;
    $entries->item($i)->nodeValue = "";
    foreach($node->childNodes as $child) {
        $entries->item($i)->appendChild($doc->importNode($child, true));
    }
}
