从文本中删除锚点 [英] Remove anchors from text

问题描述

我需要从某些文本中删除锚标记，并且似乎无法使用正则表达式来实现.
只是锚标记，而不是其内容.
例如，<a href="http://www.google.com/" target="_blank">google</a>将变为google.

I need to remove anchor tags from some text, and can't seem to be able to do it using regex.
Just the anchor tags, not their content.
For instance, <a href="http://www.google.com/" target="_blank">google</a> would become google.

推荐答案

确实，使用正则表达式无法正确完成.

Exactly, it cannot be done properly using a regular expression.

以下是使用DOM的示例:

Here is an example using DOM :

$xml = new DOMDocument(); 
$xml->loadHTML($html); 

$links = $xml->getElementsByTagName('a');

//Loop through each <a> tags and replace them by their text content    
for ($i = $links->length - 1; $i >= 0; $i--) {
    $linkNode = $links->item($i);
    $lnkText = $linkNode->textContent;
    $newTxtNode = $xml->createTextNode($lnkText);
    $linkNode->parentNode->replaceChild($newTxtNode, $linkNode);
}

每当对DOM进行更改时，向后循环很重要.

It's important to loop backward whenever changes will be made to the DOM.
