PHP简单的html DOM从html标签中移除所有属性 [英] PHP simple html DOM remove all attributes from an html tag

问题描述

$html = file_get_html('page.php');

foreach($html->find('p') as $tag_name) 
    {
        $attr = substr($tag_name->outertext,2,strpos($tag_name->outertext, ">")-2);
        $tag_name->outertext = str_replace($attr, "", $tag_name->outertext);        
    }
echo $html->innertext;

以上是我编写的代码，用于介绍< p> 标记在我的html页面并将它们删除。

我的html代码与此类似：

Above is the code I wrote to take what's inside all <p> tags in my html page and remove them.

---

My html code is similar to this :

<p class="..." id = "..." style = "...">some text...</p>
<p class="..." id = "..." style = "...">some text...</p>
<p class="..." id = "..." style = "...">some text...</p>
  <font>
    <p class="..." id = "..." style = "...">some text ...</p>
    <p class="..." id = "..." style = "...">some text ...</p>
  </font>
<p class="..." id = "..." style = "...">some text...</p>

---

如果我运行php代码，结果如下所示：

---

If I run the php code , result would be this :

<p>some text...</p>
<p>some text...</p>
<p>some text...</p>
  <font>
    <p class="..." id = "..." style = "...">some text ...</p>
    <p class="..." id = "..." style = "...">some text ...</p>
  </font>
<p>some text...</p>

不会删除< p> 标记属性位于< font> 。

如果有人可以帮助我，我会很感激。

It doesn't remove <p> tags attributes that are inside <font>.
If anyone can help me with this I'll be appreciate.

推荐答案

当我使用您的代码和示例HTML时，它不会从所有 < p> 标签，甚至是< font> 中的标签，所以我不确定你为什么不工作。

When I use your code and example HTML, it does remove all the attributes from all the <p> tags, even the ones inside <font>, so I'm not sure why yours isn't working.

但看起来像 simplehtmldom有方法专门处理属性，所以你不必使用字符串函数：

But it looks like simplehtmldom has methods that specifically deal with attributes so you don't have to use string functions:

$html = file_get_html('page.php');


foreach($html->find('p') as $p) {
    foreach ($p->getAllAttributes() as $attr => $val) {
        $p->removeAttribute($attr);
    }    
}
echo $html->innertext;

希望这会更有效。
