DOMDocument将属性添加到根标记(DOMDocument add attribute to root tag)

我想创建一些函数,为给定的html的root标签添加一些属性。

我这样做:

    $dom = new \DOMDocument();
    $dom->loadHTML($content);

    $root = $dom->documentElement;

    $root->setAttribute("data-custom","true");

而对于$content='<h1 class="no-margin">Lorem</h1>'

它返回:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html data-custom="true"><body><h1 class="no-margin">Do more tomorrow. For less.</h1></body></html>

虽然应该只是:

<h1 data-custom="true" class="no-margin">Lorem</h1>

如何让DOMDocument不创建doctype,html,body标签,而只是对给定的html进行操作以及如何选择给定html的根节点

PS。 我永远不会使用正则表达式来管理HTML。


I want to make function that adds some attributes to root tag of given html.

I'm doing this:

    $dom = new \DOMDocument();
    $dom->loadHTML($content);

    $root = $dom->documentElement;

    $root->setAttribute("data-custom","true");

And for $content='<h1 class="no-margin">Lorem</h1>'

It returns:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html data-custom="true"><body><h1 class="no-margin">Do more tomorrow. For less.</h1></body></html>

While should be just:

<h1 data-custom="true" class="no-margin">Lorem</h1>

How to make DOMDocument not create doctype, html, body tags, but just operate on given html and how to select the root node(s) of given html

Ps. I will never use regex to manage html.

它是拉丁语1减去代码点U + 0000,U + 0001和U + 0002。 这包括可以在美国键盘上找到的常用内容,大量的控制字符(低于U + 0020以及U + 007F和U + 009F之间)和一些其他拉丁字符,可以用来写大部分西欧语言。

在此处输入图像描述


It's Latin 1 minus the code points U+0000, U+0001 and U+0002. This includes the usual stuff that can be found on the US keyboard, plenty of control characters (below U+0020 and between U+007F and U+009F) and a few other Latin characters that can be used to write the majority of Western European languages.
