[Help Request] How to get REGEX working properly?

[Xelbayria]

This is from the website Sumatrapdf reader Prerelease the HTML code below

<span id="buildver">15229</span>

I used "Inspector" to look at the HTML code
The REGEX is "regex": "<span id=\"\"buildver\"\">([\\d]+)</span>"

I ran ~/bin/checkver.ps1 to test it and couldn't get it working because of this error:

couldn't match '<span id=""buildver"">([\d]+)</span>' in https://www.sumatrapdfreader.org/prerelease

Changed the REGEX to "regex": "<span id=\"buildver\">([\\d]+)</span>"
Above also got the error:

couldn't match '<span id="buildver">([\d]+)</span>' in https://www.sumatrapdfreader.org/prerelease

I have created different types of REGEXs. I am sure the REGEXs are created correctly and should be working properly. I had no problem with other websites where I want to update software in my own bucket. This one makes no sense as I couldn't figure out why. I appreciate your help with this.

The span you're trying to access is populated by JS when the page loads, so it's not present in the HTML.

Use this instead: https://kjkpubsf.sfo2.digitaloceanspaces.com/software/sumatrapdf/sumatralatest.js

eh? that was a JS? 👀 and thank you. I'll take a look at the link
🤔 how did you get the link from? this is something I would like to learn how to do on my own.

When visiting a web page, you can right-click and go to 'View Page Source', to see what the Regex will see.

In this case the buildver was not present in that source, but there was a link to a JS file at the beginning, which contained the buildver.

dang. I checked "View Page Source" and it seriously doesn't have any numbers. 👀 Now I could see why the REGEXs I created are not working. * scratching my head *
Is there another way?

A quick question, how do I get the scoop status to stop showing the "Manifest removed" message? Because I removed a bucket and add a JSON file into my own bucket. It's alright if you don't know the answer to that question.

Nvm. I tried an inspiration that just came to me and that was the answer to my question.

F12 - Developer Mode.

Check any files that downloaded locally and find the version number (maybe in JSON format). But this is a bit complex...

I don't think so. You will have to use another website.

Alright, Thank you. I understand now why it doesn't work. It's disappointing and have a good day!.
