Regex match string conditions -

since i'm not @ regex how can match conditions in string, staticstring_1number:1number:more 1number.

example:

string_3:0:12344555 - match  string_s:0:12344555 - no match  string_3:s:12344555 - no match  string_3:0:123s4555 - no match

thanks.

if understand pattern staticstring_1number:1number:more 1number correctly regex match against such strings following:

'^[a-za-z]+_[0-9]:[0-9]:[0-9]+$'

or if environment support character classes:

'^\w+_\d:\d:\d+$'
