[英]Append HTML to a tag using PHP HTML Parser
I am working on a project in which I will need to use PHP to modify the contents of any given website.我正在开发一个项目,在该项目中我需要使用 PHP 来修改任何给定网站的内容。 To do this I am using this PHP HTML Parser .
为此,我使用了这个PHP HTML Parser 。
Now, I need to be able to add a <style>
tag to the end of the <head>
of a document that's been loaded to $html
using $html->loadFromFile($url)
but I cannot seem to find an append()
method in any of the classes.现在,我需要能够将
<style>
标记添加到使用$html->loadFromFile($url)
加载到$html
的文档的<head>
末尾,但我似乎找不到append()
任何类中的方法。 Is there any way for me to achieve this?我有什么办法可以实现这一目标吗?
Here is my code这是我的代码
require("vendor/autoload.php");
use PHPHtmlParser\Dom;
$html = new Dom;
$url = "https://www.example.com";
$html->loadFromFile($url);
// I need to do this:
$css = "<style>#custom{css:code;}.goes{over:here;}</style>"
$html->find("head")->append($css);
You can find the instruction for appending an element in the documentation under "How to access the HTML element's attributes?"->"Tips".您可以在“如何访问 HTML 元素的属性?”->“提示”下的文档中找到附加元素的说明。 In this case it would be:
在这种情况下,它将是:
$head = $html->find("head")[0];
$head->outertext = $head->outertext . $css;
I think you can use it我认为你可以使用它
$head = $html->getElementsByTagName('head');
$head->appendChild($css);
