I suspect all of your regular expressions like this:

   /([\d|\.]+)/gi
[download]

Can be simplified to this:

   /([\d\.]+)/
[download]

• In a bracketed character class, '|' is literal - not "or". (The whole class is "or'd".)
• Digits and dots (and pipes) have no case, so you can omit the 'i' modifier.
• You seem to be interested in one match, so you can omit 'g' as well.
