Pro

1st Alternative(?s)<script\b[^>]*>.*?</script>(*SKIP)(*F)

(?s)applies the following effective flags to the remainder of the pattern: gms

s modifier: single line. Allows a dot to match line terminators

<scriptthe literal text <script (case sensitive)

\ban ASCII word boundary

Negated Character Class[^>]*

*matches any number of characters outside the set below:

>the literal > (62₁₀ / 76₈ / 3E₁₆)

.*?any character, repeated any number of times

</script>the literal text </script> (case sensitive)

(*SKIP)acts like (*PRUNE), but the next unanchored match attempt starts where (*SKIP) was reached instead of at the next subject character

(*F)forces the current match attempt to fail at this position

2nd Alternative\$(\w+)\[(?!\d+])(\w+)]

\$the literal $ (36₁₀ / 44₈ / 24₁₆)

Group 1(\w+)

\w+any word character, repeated at least once

\[the literal [ (91₁₀ / 133₈ / 5B₁₆)

Negative Lookahead(?!\d+])

\d+a digit, repeated at least once

]the literal ] (93₁₀ / 135₈ / 5D₁₆)

Group 2(\w+)

\w+any word character, repeated at least once

]the literal ] (93₁₀ / 135₈ / 5D₁₆)
