Hi all,


I have read that a caret signifies negation . However while doing some work i saw an expression wherein the regular expression was given as
'^[0-9][a-z][A-Z]*_[a-zA-Z]*$'.I cant understand the relevance of ^ in this perspective . Does it mean that the regular expression in the bracket should not be considered . Basically i want to know what does a ^ mean if it is at the first position in the string .

Thanks in advance .

It means that the match has to occur at the start of the string.
