正则表达式 TYPO3 链接

Question

I need to change all TYPO3 Links into real a-Tags, because I want to use it without TYPO3

Text example #1:

$strText = 'This is a  <strong>full</strong> Text
    <link https://www.example.com/news/test.html#tab3 _blank external-link-new-window "Opens external link in new window">More informations</link><br>
    Some more Text <link http://www.example.com>More informations</link>
    Text end';

I tried the following regex:

$search = '/<link\s(ftp:\/\/|http:\/\/|https:\/\/|\/)([^\s]+)[^>]*>(.+?)<\/link>/si';
$replace = '<a href="\\1\\2" rel="nofollow" target="_blank" class="external">\\3</a>';
$strText = preg_replace($search, $replace, $strText);

It is working perfectly with this text... However it is very buggy, if the order of the links is inverted inside this text

Text example #2 which result in problems:

$strText = 'This is a  <strong>full</strong> Text
        <link http://www.example.com>More informations</link><br>
        Some more Text <link https://www.example.com/news/test.html#tab3 _blank external-link-new-window "Opens external link in new window">More informations</link>
        Text end';

This results in a incorrect link which wraps both links in one.

I don't understand this and can't find a solution.

Answer 1

使用这个模式：

/<link\s(ftp:\/\/|https?:\/\/|\/)([^\s]+)[^>]*>(.+?)<\/link>/ig

Answer 2

Andy's answer was a very good hint, but that regex was not working for links that have no more attributes other than the href eg (<link https://docs.google.com/spreadsheets/d/1example/edit#gid=3333333> )

This worked fine:

<link(\s(ftp:\/\/|https?:\/\/|\/)([^\s>]+))[^>]*>(.+?)<\/link>
