RegEx In Header



i've a problem with a website.
I cannot modify the html but i can, with regex, make some change to the code.



The CMS take the first line of text and place it automatically in the header of the page in the meta description.



If in the first part of the text there are some link the CMS don't clean the html and place the link in the header breaking the page.



I was working on a regex to intercept the code and remove it.



The example of the code is:


<meta name="description" content="sometext<a href="">anchor text</a> and <a href="https://www.url.com/path1/path2">anchor</a>? a lot of text" />



The links in the text could be 1, 2, 3 or more.



At the moment i've create the:


(?:(<meta name="description" content="|<meta property="og:description" content="|<meta name="twitter:description" content="))(((?:[^<]|[^/>]*)(<(?:[^>=]|='[^']*'|="[^"]*"|=[^'"][^s>]*)*>)))



but i miss somethink.



Can someone help?



Thank you
