使用正则表达式从php中的字符串中选择html标签的一部分

Question

I would like to select the string in a div tag in php. I plan to do it with regular expression. But is there a better way?

Like this: Hello there <div>how are you?</div>. Please <div>send my regards</div> to Allan. Hello there <div>how are you?</div>. Please <div>send my regards</div> to Allan.

I would like to retrieve all texts in and together with div tag like:

"<div>how are you?</div>"
"<div>send my regards</div>"

May I know how to do?

I plan to do it with regular expression.

Nope , don't do that. The concrete reason here

But is there a better way?

Yes , use a DOM Parser for this ..

$html='Hello there <div>how are you?</div>. Please <div>send my regards</div> to Allan.';
$dom = new DOMDocument;
$dom->loadHTML($html);
$divText='';
foreach ($dom->getElementsByTagName('div') as $tag) {
      $divText.=$dom->saveHTML($tag);
}
echo $divText;
