Regex pattern to remove URL parameters/UTM

Hi all,

I need some help finding and removing any page path/UTM/querystrings from URLs using a Regex pattern.

For example, if a user visits using https://yourdomain.com/facebookpixelid?appid=test I’d like to remove that dynamic data after https://yourdomain.com including the first ‘/’ so that we just get the root domain with https:// and nothing after that.

Any idea the Regex to do so? @NigelG is this something you know about?

Thanks
Reece

Thanks Nigel, so is it just the ^(?:https?://)?(?:[^@/\n][email protected])?(?:www.)?([^:/?\n]+) in the Regular Expression input that I copy paste into Bubble? This is well beyond my knowledge here…

Yes, that is correct.

Thank you!

Regex Nigel!

I’m trying to do the opposite of this and cannot seem to figure it out.

I’m trying to get everything AFTER http://www. or https://www

I mean, it works on regex101, but its got a non-matching and a matching group, and I’m not sure how to make it work in bubble.

It is returning the whole string in bubble.

(?:^http.*://www.)(.+)

Keep it simple: You desire to remove the protocol identifier, which is everything from the start thru “//”. Find that and replace it:

Yields:

Now it doesn’t matter if the protocol is http://, https://, ftp://, some_other_protocol_nobody_uses://, etc.

Hey all - I wanted the following and @NigelG kindly helped me out in a private message. I wanted to share for all.

Goal = Extract the query string but keep more than just the root domain

Example: https://www.imdb.com/title/tt5491994/?pf_rd_m=A2FGELUUNOQJNL&pf_rd_p=12230b0e-0e00-43ed-9e59-8d5353703cce&pf_rd_r=68MZSCC1NRKFNE55V64M&pf_rd_s=center-1&pf_rd_t=15506&pf_rd_i=toptv&ref_=chttvtp_tt_1

Desired output: https://www.imdb.com/title/tt5491994/

Required regex = ^[^?]+

I realized what I actually needed to do was throw away everything from the “?” on. I managed that with a regex find and replace as follows:

Find: ?(.*)
Replace: [nothing]

https://regex101.com/ has been the tool that has finally enabled me to understand regex and make my own patterns that work for me.

breaking through some search barriers as I type this and having so much fun doing it, that I had to give you an extra nod on here for sharing it.

Hello,

So reading through this thread again I couldn’t figure how to work with a string like SULFW.M.W.HW.01

What I need is the M.W.HW.01 and remove the SULFW.

The number of the characters before the first dot varies.

I tried using the solution from @keith but ^.. (as in ^.// to remove the http// from a url) results in the entire string being removed.

Does anyone have a suggestion?

Solution to this specific question is:

^[^.]*.

I found this thread because I was having an issue that I reached out to Bubble support on. The issue is that I wanted to use a conditional that was “This URL is Website Home URL” for navigation purposes.

This should be relatively straight forward, but Bubble actually is tracking our users through the use of a ‘resume’ parameter which we don’t see in the URL except for a brief moment when the page is being navigated (at least with the go to page action).

What this results in on a home page (index page), the ‘this url’ will look like MyDomain.com

and that of course would not match the ‘website home url’ which is https://www.mydomain.com/

Bubble support told me to use a regex pattern to remove the resume parameter for my conditional to work properly.

Thanks to @GB44 for posting the pattern he used.

This works for me to remove the resume parameter from the URL.
