checkver uses wrong url

[ImMakSpy]

Hello
I'm trying to implement a manifest for my canon ts8300 driver, where checkver is
"checkver": {
"url": "https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html?type=drivers&detailId=tcm:84-1876397&os=Windows%2010%20%2864-bit%29&language=&productTcmUri=tcm:84-1876207/",
"regex": "Dateiversion.*(\d+\.\d+)"
},
There I've the problem that, when I execute the version check (checkver.ps1) I got the following error:

• couldn't match 'Dateiversion.*(\d+.\d+)' in https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html?type=drivers&detailId=tcm:84-1876397&os=Windows%2010%20%2864-bit%29&language=&productTcmUri=tcm:84-1876207/

At first I thought the regex is wrong. But after I've no clue what's wrong in the regex, I found out, that the content is from

• https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html

and not from

• https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html?type=drivers&

detailId=tcm:84-1876397&os=Windows%2010%20%2864-bit%29&language=&productTcmUri=tcm:84-1876207/".

I have the same problem, when I call

• $WebResponse = Invoke-WebRequest "https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html?type=drivers&detailId=tcm:84-1876391&os=Windows%2010%20(64-bit)&productTcmUri=tcm:84-1876207"
• $WebResponse = Invoke-RestMethod -Uri 'https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html?type=drivers&detailId=tcm:84-1876391&os=Windows%2010%20(64-bit)&productTcmUri=tcm:84-1876207' -Method GET
• curl -L "https://www.canon.at/support/consumer/products/printers/pixma/ts-series/pixma-ts8350.html?detailId=tcm%3A84-1876391&os=Windows+10+&type=drivers"

Has anyone an idea, how my problem can be solved?
I hope someone can help me.
I'm thankful for every reply.

The content is loaded via JavaScript, so you need to open the developer tools (press F12) and then you get what you need from the network tab.

https://www.canon.at/supportproduct/tabcontent/?type=drivers&os=Windows%2010%20(64-bit)&productTcmUri=tcm:84-1876207&pageTcmUri=2269755

And here a working regex: https://regex101.com/r/34zu1y/1
Dateiversion:[^\d]+([\d.]+)
Match everything that is not a number [^\d]+ and then match the version including the dot ([\d.]+)
