如何将HTML插入PHP DOMNode？ [英] How to insert HTML to PHP DOMNode?

问题描述

我有没有办法将HTML模板插入到现有的DOMNode中，而不需要编码？

Is there any way I can insert an HTML template to existing DOMNode without content being encoded?

$ b

I have tried to do that with:

$dom->createElement('div', '<h1>Hello world</h1>');
$dom->createTextNode('<h1>Hello world</h1>');

输出几乎相同，只不过第一个代码将它包装在一个div中。
我尝试从字符串加载HTML，但我不知道如何将其身体内容附加到另一个DOMDocument。

The output is pretty much the same, with only difference that first code would wrap it in a div. I have tried to loadHTML from string but I have no idea how can I append it's body content to another DOMDocument.

在javascript中，这个过程似乎是

In javascript, this process seems to be quite simple and obvious.

推荐答案

它与另一个DOMDocument一起用于解析HTML代码。但是，您需要导入节点到主文档中，然后才能使用它们：

It works with another DOMDocument for parsing the HTML code. But you need to import the nodes into the main document before you can use them in it:

$newDiv = $dom->createElement('div');
$tmpDoc = new DOMDocument();
$tmpDoc->loadHTML($str);
foreach ($tmpDoc->getElementsByTagName('body')->item(0)->childNodes as $node) {
    $node = $dom->importNode($node);
    $newDiv->appendChild($node);
}

作为一个方便的功能：

function appendHTML(DOMNode $parent, $source) {
    $tmpDoc = new DOMDocument();
    $tmpDoc->loadHTML($source);
    foreach ($tmpDoc->getElementsByTagName('body')->item(0)->childNodes as $node) {
        $node = $parent->ownerDocument->importNode($node);
        $parent->appendChild($node);
    }
}

然后你可以这样做：

$elem = $dom->createElement('div');
appendHTML($elem, '<h1>Hello world</h1>');
