Description:

i have a scalar as follows
$journal = STRUCTURE (LONDON)
when i query this in cgi, it is done so as
STRUCTURE+(LONDON)
this gives the + in the middle to complete the URL.
However in order to query the URL PROPERLY i need for my string to read
$journal = STRUCTURE LONDON
so that the CGI query is STRUCTURE+LONDON.
how can i write a regex that will remove these brackets from the string???
$journal = ~ s/ (help remove brackets) //g;
thanks in advance

or

$journal =~ s/(\)|\()//g;

"s" for replace
"\)" and "\(" for escaping the brackets
"|" for or
and the whole thing in "(..)" because you want to replace it with nothing "//"
"g" finally stands for global -> replacement doesnt stop when you hit the first bracket.
