Hi, maybe I'm simply too stupied but I've search and search now for 2 days and didn't came to a conclusion. I have to subsitute the following text in an ascii file: 
my $string = "aDescriptor.Type = {\@see Star.Awt.Win#TOP}";
$string =~ s/
  {\@see\s+((\w+\.)+)(\w+)#(\w+)}/
  <idl package="$1" name="$3" anker="$4" />
  /g;
# desired output would be :
# aDescriptor.Type = <idl package="star.awt." name="Win" anker="TOP"/>

The regular expression is already working but I could not manage to convert the the package to lower case.

In reply to Regexp matched part to lower case by tomson
