How can I use a regex to match HTML inline style attributes with "display:none"?

I’m trying to get the tag HTML in a single regex expression when I have a specific style style='display:none' and keep the content inside.

The current regex that I’m using:

(<span\sstyle=[\"\']+display[:=]none[\"\'\;]+>)|(<\/span>)

Result:

I’m getting a close </span> when it’s not supposed in the line 2 and 4. Demo

>Solution :

Try this

(<span\sstyle=[\"\']+display[:=]none[\"\'\;]+>)(?:[\w\s]+)(<\/span>)
