Need help with a regex

[Akito01]

Hey guys,

I need help with a regex for a stream, to use in Kodi's Livestreams Pro. I hope I'm in the right place here
I have this URL:

"hls":"https:\/\/live85.vkuserlive.com\/620008\/live\/0\/e0QTF6MUpgOU9vQUlFeU5SVQ\/playlist.m3u8?extra=JX7sYU9eCJn-WNVusVXOXf6U0SEaCVoRDQP6VEuwYq5vKJLWGieaPpywF41uTZd8CyrVJ2UvBWWrrLWJWZ-VYnWs82Kk-XjIYy2GK3fuQyKhGuLuGaZbrhWbw68"

And so far I have this regex:

<item>
<title>streamtest</title>
<link>$doregex[get-final]</link>
<regex>
                <name>get-final</name>
                <expres>$pyFunction:'$doregex[get-m3u8]'.replace('\\/','\/')</expres>
                <page></page>
</regex>
<regex>
				<name>get-m3u8</name>
				<expres>hls":"(.*?)"</express>
				<page>https://vk.com/video_ext.php?oid=447032045&id=456239055&hash=87967896e0c868e4&autoplay=1</page>
</regex>
</item>

However the link won't open and I suspect it's got something to do with replacing the chars \/ for a / that goes wrong.
Can anybody help me out here? Thanks so much already!
