Recovering text between parentheses using regexp
显示 更早的评论
Hi,
I am trying to create a regular expression using which i can recover the string between two parenthesis. I have created the following expression
exp='[^(]+.*[^)]+';
matchStr = regexp(str,exp,'match');
This expression works fine if the string is off any one of the formats mentioned below:
a) str = '(1r)';
b) str = '(0.5;0.5;'rrr')'; etc
but does not work if the string is off the form
str = '(r)'; or str = '(1)';
i.e. it doesn't pick up string which are just off 1 character between the parenthesis. I think i am missing something very basic here. Is it that regex will not work for single characters and will only work for strings?
Thanks in advance,
Regards,
Giri

exp = '[^()]*'; should be it.

doc regexp
[^c1c2c3]: Any character not contained within the brackets.
expr*: 0 or more times consecutively.
