$1 ~ $999
Stands for what a certain group captured. If the number is larger than the max group number, DEELX will use less digitals, till the number is smaller than or equal to the max group number.
If the max group number is 20, "$999" means "$9" and common string "99", while "$15" means the 15th group. If you need "$1" and common string "5", you can use $0015 , DEELX at most recognize 3 digitals as number.
Stands for what a named group captured.
Stands for a single dollars ($).
Stands for what the overall expression captured.
The substring before the beginning of what the overall expression captured in the original text.
The substring behind the end of what the overall expression captured in the original text.
