使用 php 剥离 html 标签

内的内容之外的html标记

我怎样才能去除除预标记代码

$content="
    <div id="wrapper">

    Notes


    </div>


    <pre>
    <div id="loginfos">asdasd</div>

    </pre>
";

当使用strip_tags($content,'')时，预标记内的html也被剥离了。但我不想把里面的 html 预剥离掉

尝试：

echo strip_tags($text, '<pre>');

Try :

echo strip_tags($text, '<pre>');

您可以执行以下操作：

使用 preg_replace 和 'e' 修饰符将 pre 标记的内容替换为一些字符串，如 @@@1@@@、@@@2@@@ 等，同时将此内容存储在某个数组中
运行 strip_tags ()
再次运行带有'e'修饰符的preg_relace，将@@@1@@@等恢复为原始内容。

有点笨拙但应该可以。

好吧！，你只留下一个选择：正则表达式......没有人喜欢它们，但它们确实能完成工作。首先，用一些奇怪的东西替换有问题的文本，如下所示：

preg_replace("#<pre>(.+?)</pre>#", "||k||", $content);

这将有效地将您的内容更改

<pre> blah, blah, bllah....</pre>

为其他内容，然后调用

strip_tags($content);

之后，您可以替换 ||k|| 中的原始值（或您选择的任何内容），然后您'就会得到想要的结果。

Ok!, you leave nothing but one choice: Regular Expressions... Nobody likes 'em, but they sure get the job done. First, replace the problematic text with something weird, like this:

preg_replace("#<pre>(.+?)</pre>#", "||k||", $content);

This will effectively change your

<pre> blah, blah, bllah....</pre>

for something else, and then call

strip_tags($content);

After that, you can just replace the original value in ||k||(or whatever you choose) and you'll get the desired result.

我认为您的内容在 $content 变量中存储得不是很好，

您可以通过将内部双引号转换为单引号来检查一次吗

$content="
    <div id='wrapper'>

    Notes


    </div>


    <pre>
    <div id='loginfos'>asdasd</div>

    </pre>
";


strip_tags($content, '<pre>');

I think your content is not stored very well in the $content variable

could you check once by converting inner double quotes to single quotes

$content="
    <div id='wrapper'>

    Notes


    </div>


    <pre>
    <div id='loginfos'>asdasd</div>

    </pre>
";


strip_tags($content, '<pre>');
