Hi there,
I'm quite new to perl, and now having problem with using parentheses
in translation strings. For example, I want to replace the 4 digit
year code 'yyyy' with '(\d\d\d\d)', so it can be used for grouping in
string matching later. I expected the code would be like:
$org_str =~ tr/yyyy/\(\d\d\d\d\)/;
Then the result is '(((('. It seems the parens were not escaped
properly, shouldn't the backslash escape the round brackets? If I
remove the backslashes before brackets, the result is the same. If I
use double backslashes, that is, \\(\d\d\d\d\\), the result is '\\\\'.
Can someone inform the right way to do this? Many thanks in
advance! :-)
