删除标签但在php中的标签之间保留字符串 [英] remove tag but keep string between tag in php

问题描述

我有从其他网站获取内容的文件.它包括很多:

<脚本>[随机] 字符串 2....<脚本>[随机] 字符串 n<script type="text/javascript">必须保留脚本<script type=text/javascript'>必须保留脚本

我想删除 <script> 和 </script> 但使用 PHP 保留它们之间的内容[随机] 字符串 ...".>

注意:str_replace 可以删除它们，但可能会影响其他脚本<script type="text/javascript">必须保留</script> 和 <script type='text/javascript'>必须保留</script>.它将丢失必须保留脚本的关闭标签</script>

感谢您的帮助

//求解:

$content = preg_replace('/(<脚本>[随机] 字符串 2....<脚本>[随机] 字符串 n";$content = str_replace(array("<script>", "</script>"), "", $content);

由于您想摆脱 并同时保留 <脚本>[随机] 字符串 2....<脚本>[随机] 字符串 n<script type='text/javascript'>必须保留脚本<script type='text/javascript'>必须保留脚本";$dom->loadHTML($content);$scripts = $dom->getElementsByTagName('script');foreach ($scripts as $script) {如果 (!$script->hasAttributes()) {回声 $script->nodeValue ."<br>";}}

这将输出:

[随机] 字符串 1
[随机] 字符串 2
[随机] 字符串 n

I have file which get content from my other site. It is clude lot of:

<script>
[random] string 1
</script>

<script>
[random] string 2
</script>
....
<script>
[random] string n
</script>

<script type="text/javascript">
must keeping script
</script>

<script type=text/javascript'>
must keeping script
</script>

I want to REMOVE <script> and </script> but KEEP content between them "[random] string ..." using PHP.

Note: str_replace can remove them but may make hurst other scripts <script type="text/javascript">must keeping</script> and <script type='text/javascript'>must keeping</script>. It will lost close tag </script> of must keeping script

Thanks for helping

//SOLVED with:

$content = preg_replace('/(<script>)(.*?)(<\/script>)/s', '$2', $content);

Anyway, thanks for helping

解决方案

Try this

$content = "
    <script>
    [random] string 1
    </script>

    <script>
    [random] string 2
    </script>
    ....
    <script>
    [random] string n
    </script>    
";

$content = str_replace(array("<script>", "</script>"), "", $content);

EDIT: Since you want to get rid of <script></script> and in the same time keep <script type="text/javascript"></script> and because using regexp to solve this kind of problems is a bad idea then try to use the DOMDocument like this:

$dom = new DOMDocument();

$content = "
    <script>
    [random] string 1
    </script>

    <script>
    [random] string 2
    </script>
    ....
    <script>
    [random] string n
    </script>

    <script type='text/javascript'>
    must keeping script
    </script>

    <script type='text/javascript'>
    must keeping script
    </script>    
";

$dom->loadHTML($content);
$scripts = $dom->getElementsByTagName('script');

foreach ($scripts as $script) {
    if (!$script->hasAttributes()) {
        echo $script->nodeValue . "<br>";
    }
}

This will output:

[random] string 1
[random] string 2
[random] string n
