question about :matches_regex

oh

 

got it

 

 

It is not me who use this matches_regex

 

 

Another engineer use this and I need to maintanian this irule ,but confused by ()

 

So you mean we use a capturing group by the expression in () to capture the matched characters

 

 

for example ([0-9]) test321654654

 

 

so 321654654 will be captured to $match

 

 

and if I use () in matches_regex ,because matches_regex doesn't support saving the matches,so it is useless.it will only work like a normal character without ()

 

 

I mean matches_regex will ignore () in my case

 

 

right?
