How to extract some value that are whitin html code

thank you for your reply,
Not always the number is with dots, the value is percent value, it could be 60%, or 25% or 14.77% as the above example.
I also tried your code:
regex=(?<=title=[",“])\d+.\d+ | title
in Notepad++ and in this website

in Notepad++ it did find the text “title” twice, in the above url it did not find anything, it gave error, and in Kantu it did not find anything.

I also tried this:
“[0-9][0-9.]*[0-9]”
exactly as it is with quotes, on Notepad++ and in the above url (freeformatter.com) it did return the value 14.77,
but when I tried it on Kantu, it did not find anything.

Edited: this is the part of Kantu macro i used:

“Command”: “sourceExtract”,
“Target”: “[0-9][0-9.]*[0-9]”,
“Value”: “c2”

thanks
