Hi all,

I wonder what is the regular expression for this line. What I try to do
is to remove "(some text here)" from a long string.


Thanks,

Li


string=......(some text here).......

This works.

"......(some text here).......".sub('(some text here)','')

Li,

Well, there are few different ways.

string.sub!(/\(.*?\)/,'')
string.sub!(/\([^)]*\)/,'')

If there's a chance that there will be nested parentheses, you'll need
something more complicated.

It seems like you're often asking regular expression questions. I'd
highly recommend picking up Mastering Regular Expressions by Jeffrey
Friedl. After reading just the first two chapters, you'll be able to
figure stuff like this out very easily. After reading a few more
chapters, you'll know the difference between the two expressions above
and which one you want to use.

HTH,
Chris

Hi Chris,

Thank you very much. I will take a look at "Mastering Regular
Expressions".
