Hi @shreyasminocha and @ionutvmi, Thank you for this amazing library! I have been trying to generate a regex for the following statements: 1. There is no entry for **min-power-bark** or **max-power-bark** in the text 2. The values for **min-power-bark** is **9** and **max-power-bark** is **127** Expressions I have tried, but I am able to get them to work: ``` 1. VerEx() .beginCapture() .not(min) .or() .not(max) .endCapture(); Regex : /(?:((?!min-power-bark))|(?:(?!max-power-bark)))/gm ``` ``` 2. VerEx() .beginCapture() .then(min-power-bark+ ": ") .beginCapture() .digit() .repeatPrevious(1) .endCapture() Regex: /((?:min-tx-power\: )(\d{1}))/gm ``` Could anyone please help me with this ?
